The EPB-303 is a low cost milligram scale and a great alternative model if you are trying to replace either the Acculab VIC-303 or Sartorius AY303.. This digital scale offers 300 grams weighing capacity and the display resolution increments in 0.001 gram divisions. You have the choice of 13 additional weigh modes and changing the weighing mode couldn't be easier - just press the "UNIT" keypad. Other scale manufacturers make you enter cryptic codes like "6.1.2" for pennyweight by pressing multiple keypads in a specific sequence. Enter the wrong number or don't follow the pressing of the buttons in the right sequence order and who knows what mode your digital scale will be weighing in. Not with the EPB-303 - just press the "UNIT' keypad and you can change the weigh unit from Grams to Ounces to Pennyweight to Carat to Grains with a press of the keypad. It's simple and easy.

EPB303 milligram scale can be operate on either AC Adapter which is included or 6 AA batteries that are not included. This is another nice design since many competitor brands don't operate on standard off the shelf AA alkaline batteries that are available also everywhere. Some manufacturers design their digital scale with either special proprietary design rechargeable batteries that you can only buy from them at an inflated price or they use a sealed lead acid battery with the battery terminals hard soldered. So when the lead acid battery loses its ability to hold a charge if you don't have a soldering iron and know how to solder then your scale it inoperable. All these issues are eliminated with the EPB303 since it uses off the shelf regular AA batteries. If you are always near a power receptacle just run the digital scale on the AC Adapter.

Calibration is easy with the EPB303 and the 200 gram steel calibration weight that is chrome plated is included. The weight has no class tolerance nor certificate, but since it is made of steel we would say it is probably Class 6 tolerance. The weight is made in China and it isn't like the high quality Troemner Class 1 calibration weight we sell which are made of stainless steel. For the price you are paying for the EPB-303 it is amazing any weight comes with the scale.

A nice feature of the EPB-303 is the milligram scale has a 3 door draftshield that is made of glass. Many similar milligram scales in this price range typically have a plastic draftshield. The problem with plastic is it is more prone to creating a static electricity issue resulting in erratic weighing results. Plus the EPB303 has 3 sliding doors (right, left & top) allowing you easy access to the weighing pan.

Additional, selling points are four(4) adjustable feet to level your scale with the sprint leveling bubble indicator located next to the ON/OFF keypad. Some other brands in this price range have no leveling bubble and no adjustable level or maybe only 2 front adjustable feet so you better always have a table that is perfectly level. Whenever weighing the digital scale must be level to give accurate weighing results.

This affordable milligram scale incorporates a strain gauge loadcell which allow the price to be so low compared the electromagnetic force restoration like the A&D FX-300i or Sartorius Entris323-1S. Although the scale increments in 0.001 gram graduation for strain gauge scale you need to look at the linearity(aka accuracy) in the specification table. The EBP303 linearity is stated at ± 5d. "d" states for division(what the display increments in). So the EPB303 increments in 0.001 gram divisions so you could expect the milligram scale to be accurate to ± 0.005 grams. To get this performance you need to have the scale level using the 4 adjustable feet, calibrate the scale and have the scale should be plugged in for at least 30 minutes - ALL strain gauge scales have warm up times otherwise you will really see the scale drift a lot. We really don't recommend buying a strain gauge milligram scale because even if you set up the scale correctly and do everything right a strain gauge loadcell performs poorly when weight is added or removed slowly from the weighing platform (weight loss/gain over time). They should never be used for ammo reloading or pharmacy compounding where weight is slowly being added to the weighing platform. Be sure to review this youtube video for a better understanding - "Magnetic force restoration (MFR) balance verses strain gauge digital scale".

Some people might say why are you selling something you don't recommend buying and it is simple - people want a cheap answer and they don't care what you have to say and they are not going to spend $700, $1000 or more for a real MFR milligram balance. The scale manufacturers have listened to the marketplace and the EPB-303 isn't the only strain gauge milligram scale. We also offer the Acculab VIC-303, Sartorius AY303, MyWeigh Gempro250, Adam PGL303 and there are many others. Sartorius which owned Acculab discontinued the Vicon and AY milligram scale probably from so many complaints about the strain gauge drifting especially for gun and ammo reloaders We just want you to be aware what you are buying and our web site has plenty of information detailing the product and numerous youtube videos. Again some people are not going to spend the money for MFR balance and if all you have is under $320 the EPB-303 is an affordable milligram scale that offers a real glass draftshield. Many other milligram scales have a plastic draftshield that is a lot cheap and contribute to more static electricity issues.

The EPB303 has a 3.85" inch diameter weighing platform. The balance features a 3 door glass draftshield that is NOT removable. Bright backlit display makes viewing fast & easy in any lighting. You can program the backlit to always be ON, always OFF, or when a weight is applied to the weighing platform the backlit automatically turns ON. The EPB-303 is backed with a 2 year limited manufacturer warranty against defects.

If the EPB-303 isn't exactly what you need for your weighing applications then be sure to see the additional models in the EPB Series HERE.

The video above highlights the general features of the EBP203 milligram scale. We walk you step by step how the calibrate the scale. Learn how you can change the weigh mode from grams to pennyweight and how the scale will power up in the last weigh mode used. The features highlighted in this video are similar for the EPB103 and EP303 except the weighing capacity is 100 grams and 300 grams respectively. This is an affordable milligram scale ideal for the science classroom or hobbyist weighing small samples. In grains mode the scale increments in 0.02 gains and would NOT be sensitive enough to weigh to the kernel for those benchrest shooters you need to buy an analytical balance that weighs to 0.0001 grams or 0.002 grains.
 
 
Gun and ammo reloaders really need to watch the video above. See the Sartorius Entris64-1S in action and where professional shooters all over the world are learning to forget those low cost strain gauge scales that don’t work (see this video to see the difference). See how the RCBS10-10 beam scale can not even sense the weight of a kernel of powder. Watch the Omega Powder Trickler drop one kernel at a time. A kernel of Hogdgon H4350 powder weighs between 0.020 - 0.030 grains and the Sartorius Entris64-1S increments in 0.002gn. If you are tired of all the headaches using digital scales in the past it is time for you to buy a real balance that can weigh correctly.
 
Be sure to review this youtube video for a better understanding the performance you get from strain gauge digital scale verses magnetic force restoration (MFR) balance. If you are weighing static objects a strain gauge loadcell might work good enough for your weighing task, but if you are weight loss or gain over time you really need to find money money and buy a magnetic force restoration milligram balance.
