ECS-3LB Electronic Counting Scale offers 3.3 lb weighing capacity and increments in 0.0001 lb intervals and in the second weigh mode, 1.5 kg weighing capacity and 0.00005 kg graduations. This counting scale is powered by AC adapter or the internal rechargeable battery and features a 13.25" x 9" weighing platform. The rechargeable battery is factory installed and included with the counting scale and offers more than 25 hours of battery life when fully charged.

This counting scale is an excellent choice for weighing small parts in the range of 0.25 grams or more. We understand many people don't have a scale to weigh their part so to give you an idea what 0.25 gram would be simply take a paperclips off your desk and straighten the wire out and then break the wire into two equal pieces. Well half a standard paperclip weighs about 0.25 grams. If your part is a lot heavier than 0.25 grams then be sure to see the other 5 models of the ECS Counting Scales here.

When you talk to every "so called scale expert" many don't have a clue about the proper selection of which counting scale model best meets your needs. Many like to exaggerate on the counting scale's ability to count parts and will attempt to impress you with buzz words like 'internal counts a.k.a. counting resolution" and enhance APW Software that is suppose to solve all the problems in the world.

The first thing you need to understand is all manufacturer state specifications in "best case scenarios" like every part you are attempting to count is uniform in weight, which isn't reality. If you are counting paper the paper can hold moisture, if you are printing on the paper one sheet can have more ink applied than the next piece of paper. Fabricated metal and plastic items can always have burrs or residual lubricant used in the manufacturing process. It is always best to use a larger sample size like 20 or 25 parts verses 5 or 10 pieces to better adjust for variations in the parts you are counting.

Our successful selling of counting scale has always been "if the counting scale can't sense the sample weight then it can't count it" so look at the smallest graduation the counting scale increment and multiple this number by 4 or 5 for extra security and your count should be good. So the ECS-3LB increments in 0.00005 kg (equivalent to 0.05g). We like the metric system so 0.05g x 5 yields 0.25 grams. So if your part weighs greater than 0.25 grams (that's about the weight of half a standard paper clip) then the ECS-3LB will do the job, but you'll also have to remember this scale only has a weighing capacity or 1.5kg or 3.3 pounds. If you are counting lots of parts this counting scale has an accumulator function.

Be sure to scroll completely down this web page since we have an ton of information to help you better understand how a counting scale works. You'll learn how if you don't have parts that weigh all the same you'll never be able to count them correctly. You'll learn about average piece weight and more. Please, first read everything on this web page to get a understanding of a counting scale and if you have questions give us a call and we'll help you out.

Versatile ECS Counting Scales are used for weighing applications involving piece counting, inventory control, or straight weighing. This is a generic brand direct from Asia, but this is where 99% of the electronic counting scales are made now a days. Asia has advanced dramatically over the years in technology and quality. We decided to market this generic brand since we believe the motto "if you can't tell the difference why pay the difference". Again, if you are confused and not sure give us a call and a product specialist you can "count on" will give you a hand in getting the best counting scale for your application and money.

Large removable stainless steel weigh pan for easy clean up.  The scale design incorporates a 4 post platform for better weighing results especially with corner weighing.  Many other brands are designed with only a single post in the center resulting in greater eccentric weighing errors.  You can determine how much the eccentricity of the load will affect the weighing results on the scale by weighing the same weight at the corners of the weighing platform.  The 4 post design has a greater manufacturing cost and this is why many of the major brands of scale manufacturers cut corners to maximize their profits while diminishing your accurate weighing results.

The ECS Series Counting Scales includes a choice of 6 different models to meet almost any parts counting application.  These economically priced digital counting scales allow you to purchase your own counting scale for practically the same amount your local scale company or equipment rental company would charge for a 2 week rental.  Purchasing your own counting scale eliminates the chances of being told "all of our rentals are out, try us back next week".

Applicable applications for the ECS Series include:
  • Electronic parts like 1/2 watt resistors use the ECS-3LB
  • Contract manufacturers for kiting up small hardware like a 3/8" nuts or 1/4" bolts select the ECS-7LB
  • Copy centers or print shops can count business card ECS-16LB
  • Copy centers or print shops can count standard 8 1/2 x 11 sheet paper or business cards with the ECS-33LB
  • Media fulfillment centers counting CD Roms or media packs choose the ECS-66LB
  • Plumbing contracting counting out 1/2" copper fitting for the job maximize their profits with the ECS-110LB
  • Determining the length of cable, hose, chain & rope. One might ask how could a counting scale determine the length? Measure out 25 feet of cable > enter a part count of 25 pieces > and now your counting scale will determine the feet of cable on the scale. The ECS-110LB works great for counting 14/3 romex cable typically used to wire homes.
  • Metal fabricator to count heavy parts weighing 1/4 of a pound or greater.  We really don't recommend the ECS-110LB since although you can count parts and have up to 110 pounds on the counting scale the weighing pan is only 13.25 x 9 inches.  So really unless you are counting parts that are extremely heavy like lead weights for a scuba driver's weight belt then we would say this model is impractical.

No matter what counting scale you purchase one thing is imperative - the item you are counting must be uniform in weight.  In order for counting scales to count the scale must be able to determine the average piece weight (APW).  It is the responsibility of the operator to tell the scale how many pieces of the same item are on the weighing platform in the beginning for the counting scale to compute the APW.

This is accomplished by hand counting out a sample lot of 10, 25, 50, 100 pieces, placing them on the platform and then pressing the Sample/Unit Key on the ECS Counting Scale.  One of the beauties of this counting scales is you can set any sample size.  You're not restricted to a factory setting sample size of 5, 10, 25 pieces like comparable models on the market.  If you want to use a sample size of 57 pieces, and then you count out 57 pieces, place them on the platform, enter 57 using the 1-9 keypad and then press the Sample/Unit Key.  Your counting scale is now programmed to count away.  Place a hand full of additional parts on the platform and the scale will display the piece count.  It's easy, simple and fast saving your company hours over manual hand counting.

The ECS Series also allows you to manually enter the unit piece weight if you already know the APW.  Simply enter the unit weigh using the 1-9 keypad and then press the "Unit Weight" key to store the unit weight.  This can be a huge time saving feature over competitor's models.

An example would be if you were a storekeeper for a plumbing contractor.  Your job is to kit up fittings and other hardware for jobs limiting issuing any extra supplies.  In all likelihood any extras would simply disappear and the plumber on the job site would end up taking these parts home for those midnight jobs after work and on the weekends.  If you know a 1/2" right copper elbow weight 18.1 grams versus a copper 1/2" T fitting weighs 27.4g or a 1/2 copper end cap weighs 7.1g you simply enter the value in and count away.  Time is money and the ECS Series will pay for itself in labor cost savings in weeks or even days depending upon your usage.

Counting scales look at the weight on the weighing platform and divide the weight by the number of pieces to compute the APW.  It's truly a simple process.  You're just basically training the counting scale that 1 widget that weighs say 25.4g is equal to 1 piece.

Another issue to successful implement with any counting scale is you must have pieces (widgets) that have a consistent weight.  No counting scale will ever work if there is a significant variation in the weight of the widgets.  How much error will be dependent on how much the weight of individual pieces varies?  The larger the initial sample (say 100 pieces versus 10 pieces) the better results the counting scale can provide since it averages out any variations.

Let's take a look at how inconsistent weights can affect the counting scale.  In the example below we weighed out each washer on a lab balance to show the effects that weight variations have on any counting scale.

Piece weight needs to be consistent
= 1.0g = 1.0g
= 1.0g = 1.0g
= 1.0g = 1.0g
= 1.0g = 1.0g
= 1.0g = 1.0g
        10g total weight           
=   -------------------------------
1g sample unit piece weight

= 10 pieces (no error)
If the 10 pieces are inconsistent
= 1.0g = 1.4g
= 1.1g = 1.3g
= 1.2g = 1.3g
= 1.1g = 0.9g
= 1.3g = 1.4g
        12g total weight           
=   -------------------------------
1g sample unit piece weight

= 12 pieces (2 piece error)
High resolution counting scales have been in the market for over 25 years.  Half million internal resolution counting scales use to sell for $2500-3500 each.  Today, you can get as good, if not, a better scale for about 10% of this price.

The ECS counting scales are competitively priced and are built with the highest quality components.  Here are the reason why your next purchase of a counting scale should be the ECS.

  • Platform size: 13.5 inch x 10 inch – lots of space to work with and to count.  Competition offers a lot smaller in physical size.
  • Platform: heavy gauge stainless steel platter.  Competition uses thin stainless cover that sits on a plastic platter.
  • Sub-platter design.  The sub-platter is made from a die cast heavy duty and stiff aluminum die cast which is mounted right on the load cell.  The bottom of the load cell is also mounted to a stiff aluminum die cast.  Steel footings are then mounted right on the bottom die cast structure.  Competition uses pressed steel sheet.  They are cheaper and steel bends and will affect the scale accuracy.  Many of them have the load cells mounted on a steel plate that sits on the scale bottom housing.  Plastic footings are screwed into the plastic casing.  This is a bad design because plastic flexes and produces counting errors.  Your expensive component weight is only transferred to a heavy gage stainless steel, supported by stiff die cast aluminum sub-platter that is mounted right on the sensor.  The bottom of the sensor sits on another aluminum sub-platter, and the weight of the component and the scales are transferred through steel footing to the top of your work bench.  No costs are reduced in this construction.
  • Sensor: The ECS counting scale uses the most expensive and the most reputable German HBM load cells.  The heart of weighing is the load cell, the counting accuracy is only as good as the sensor used.  Competition may provide unknown brand sensors that cost less than ¼ as much.  Cheap sensors have poor performance, giving you a “curvy” shape in counting accuracy instead of a straight hard linear resolution.
  • A/D processor or analog to digital processor.  ECS Counting Scales uses the fastest US-made A/D processor.  You get over 1.3 million internal resolution and less than 1 second display update time.  The internal resolution is like a magnifying glass, a high internal resolution will help the scale see the additional one unit more or less that you have on the scale.  It is also very important in capturing minute changes in weight or counts, many lower cost products will only use the software to lock the display, and when you put 1 small piece on the scale, it will not be able to detect the weight change.  This is VERY BAD because if small amount of products are placed slowly or taken out slowly from the scale, it will not capture the change and just assume the previous weight or count.
  • The fast update is also important which is similar to running your Window XP on an Intel 286 processor.  If you have all the time in the world, it is ok to buy from the competition, if not, this is the fastest you can buy.
  • Large back light displays that is easy to read, accumulation functions, 9 memories, easy operations and a one year warranty are some of the other areas that put this as the best value counting scale in the world today.  Match this with something costing 2 or 3 or even 4 times more.  Stretch your hard earn dollar and buy smart.
