Ohaus Pioneer PA163 milligram balance from Ohaus Corp. offering 0.001 gram readability. The Ohaus PA163 scale weighs up to 160 grams, features a draftshield, and applications include weighing, parts counting, percent weighing, density determination and dynamic weighing applications. Ideal for basic weighing, the Ohaus Pioneer digital scale is designed with the economy in mind. Ohaus understands not everyone is looking for a fancy touch screen display and other bells and whistles, but instead an affordable balance for basic weighing.

The new Pioneer PA163 Plus replaces the discontinued Ohaus PA153. The Pioneer Plus offers new features like a backlight display and density determination function. An optional density kit is available or use the built-in weigh below hook allowing you to suspend an item below the balance to calculate specific gravity.

All Pioneer Plus Milligram Balances are constructed with a metal base, ABS top housing, stainless steel pan, glass draftshield with sliding top door, up-front level indicator security bracket, calibration lock, user selectable communication and printing settings, auto standby, mechanical and software overload protection and replaceable in-use cover.

Pioneer Plus Balances models use a magnetic force restoration weigh sensor, not a cheap strain gauge that is prone to drifting with the numbers on the display moving even though you added nothing to the weighing platform. We get so many calls from end users saying they purchased some no name brand made and they hate their balance since it is a strain gauge. If you don't understand then watch this video HERE demonstrating a magnetic force restoration balance verses strain gauge scale.

Choose from 6 different milligram balance models in the Pioneer series with either a capacity of 160 grams or 520 grams. You can review the complete line of Ohaus Pioneer milligram balances HERE.

Ohaus Pioneer milligram scale was designed for basic routine weighing in a variety of laboratory, industrial and education applications. With the right combination of performance and features, the Ohaus Pioneer offers uncomplicated performance for all your basic weighing needs.

Standard Features Include:

  • Easy to Clean Draftshield – Pioneer’s draftshield is designed with all glass panels, including three sliding doors. All panels are easy to remove and replace, and together with a stainless steel bottom, make it fast and easy to clean
  • Upfront Level Indicator – Pioneer has been designed with an up-front level indicator, so that users can quickly ensure the balance is level prior to use
  • Selectable Environmental Settings – Three filter modes and adjustable zero tracking adjust balance sensitivity to environmental disturbances, or application requirements
When the Ohaus PA163 balance is first installed, or is moved to another location, the milligram balance must be calibrated to ensure accurate weighing results. The Ohaus PA163 requires the purchase of a optional external 100 gram calibration weight to perform calibration. We always recommend that you purchase the calibration weight when you purchase the milligram balance. You can learn more about calibration weights, class weights and the tolerances at

Is the Ohaus PA163 too expensive for your budget??? We also offer the AND Weighing AND FX120i (120 g x 0.001 g), AND FX200i (220 g x 0.001 g)or AND FX300i (320 g x 0.001 g) all priced substantially less than the Ohaus PA163.

Many people call us looking for the absolute best value Precision Weighing Balances can offer in a milligram balance and the answer again and again is the A&D FXi milligrams balances. We believe the value is unmatchable in the AND Weighing FX200i since you get lightening fast weighing results, 220 grams weighing capacity with 1 milligram readability and topped off with a 5 year limited manufacturer warranty at a low price.

Looking for a balance that comes standard with a USB interface? Be sure to see the new Sartorius Practum 213-1S and Quintix 213-1S milligram balance. The Sartorius features a touch screen user interface for easy balance configuration. Don't want to spend the money for the fancy touchscreen or USB interface but still want the Sartorius brand? Then be sure to see the Entris323-1S. We have used all of the major brand laboratory balances and without a question Sartorius builds the best performing lab balance for speed and accuracy.

US government customers call us saying the must comply with the Buy American Act clause the only similar balance we offer to the PA163 that is made in America would be the Scientech ZSP150. FAR Part 25.003 requirements state that domestic end products are preferred over foreign end products, and the Ohaus Pioneer is not made in the USA.

We understand purchasing an milligram balance is a major capital expense and if you have any questions give us a call and one of our weighing experts can discuss your weighing application and get you the most affordable balance for your weighing needs.

Ohaus Pioneer laboratory balance weight display
The new Ohaus Pioneer Pro Series features a red overlay keypad display and bright backlit LCD display provides ample lighting, making the display very easy-to-view in laboratories with dim lighting. The predecessor model, Ohaus PA153, had a blue overlay and no backlight display. The spirit bubble is located to the right of the weighing display so you can verify at a quick glance that your balance is level for optimum accuracy. The Ohaus Pioneer Pro Series now features the "Density Determination" weigh function. These great new upgrades we believe will increase the demand even more for this basic entry level milligram balance.
Lab balance with optional scale printer
On the rear of the balance you'll find a built-in RS232 allows connection to an Ohaus SF40A impact printer or a computer. Sends Balance ID plus spaces for recording User ID, Project ID, time and date.

Integral security bracket allows you to secure your balance to a workstation to prevent unwarranted movement or theft

The 2 adjustable rear leveling feet level indicator helps to ensure that the Ohaus balance is level.
Weigh below hook for specific gravity
The Pioneer Pro balance is now equipped with a weigh below hook for weighing below the balance. Before turning the balance over, remove the pan and draft shield elements to prevent damage. The black removable protective cover is the weigh below underhook opening. To use this feature, remove power from the balance, then remove the protective cover for the weigh below opening. The balance can be supported using lab jacks or any other convenient method. Ensure the balance is level and secure. Power on the balance, then use a string or wire to attach items to be weighed. Below weighing is used for weighing magnetic materials, large samples that won't fix on the weighing platform or extremely hot or cold sample that would effect the balance's electronics if placed directly on the weighing platform due to thermal heat/cold transfer. Additional applications would be specific gravity determination.
Ohaus digital scale usb drive for storing weighing data
An OPTIONAL PAD7 Auxiliary Display Kit for Pioneer is available. This secondary display can be useful in science and chemistry classroom setting allowing students to see the weight display without being direct over the balance looking at the display. This second display plugs into the RS-232 port on the rear of the balance.

Are you going to be performing density determination of samples? You'll need to purchase the OPTIONAL Ohaus Density Determination Kit. See how to install and use the Ohaus Density Determination Kit. This YouTube video shows the density kit with the Ohaus Explorer but it is somewhat similar to the Pioneer. You'll see exactly what comes with the kit.

Sartorius Secura Laboratory Balance offer advanced weighing features compliant with the USP minimum sample weight requirements. The balance's display indicates when the minimum sample weight is below the required minimum weight limit.

Secura guarantees high reliability and security in regulated areas for the most common weighing ranges. Quintix is convenience in operation, calibration and data transfer. Even Practum features weighing technology at the highest quality level.
Before you make your final decision be sure to see the Sartorius Entris323-1S, 423-1S or 623-1S milligram balances. The Entris is made in Germany and production will soon be moved to Sartorius' manufacturing facility in Colorado. Watch the video above on the Sartorius Entris Milligram Balance and how easy calibration is when you purchase the optional calibration mass. The Sartorius Entris 3 decimal place balances offer a circular draftshield that you load from the top. See the quick settling time as we place calibration weights on the weighing platform.
The A&D FX200i is an amazing milligram balance that is back with a much longer warranty than the Ohaus PA163. 5 years verses Ohaus is only 2 years. Plus the A&D offers a smaller footprint saving you valuable lab space. In addition, if you are weighing in a hostile environment that is extremely dusty or wet AND Weighing is one of the few balance manufacturers in the world that offers an IP65 rated dust and water resistent milligram balance. See the A&D FX200iWP washdown scale or A&D FZ200iWP Internal Calibration Scale.
If you are a jeweler or pawnshop buying and selling gold, platinum, palladium or rhodium the PA163 is NOT legal for trade and you will run into a lot of trouble with weights and measures and possibly hefty fines. Don't take chances of being in violation. Instead purchase the A&D FX200iN legal for trade balance with 220 grams weighing capacity that displays to 0.001 grams division and the verification scale division of 0.01 grams. The FX200iN would also comply with pharmacies requiring a Class "A" prescription scale to maintain their pharmacy license when the requirements are a weighing device with a minimum tolerance of 0.1 grains or 6 milligrams.
