Product Details

Stackable For Compact Storage You can stack up to three of the Newton balances for neat, compact storage...perfect for schools and other places tight on space.

Programmable Auto-Off Feature If you've ever had your scale turn off on ya in the middle of important measurements, you'll realize what a blessing this feature is. You can program the Newton balances to turn off automatically, or to stay on until you turn them off yourself.

Programmable Backlight You can even program the backlight for the EJ300. If ya work in dim environments, you can set the backlight to always on, or to turn on when ya press a button or change the weight on the scale. If ya don't really need a backlight, just set it to off. No unnecessary power use here.

Tare Feature The tare button on the front of this digital scale can be pressed to "zero out" the weight on the scale. You can then add more weight, and the display will only show the weight of the item you're adding. This sure is useful when ya want to use a separate weighing container or get the weights of separate items.

Stainless Steel Platform This compact digital scale has a durable stainless steel weighing platform to make cleanup a breeze. Unlike gold or silver, stainless steel doesn't scratch easily and keeps its shine without rusting or tarnishing. This scale's platform is perfect for weighing smaller items. Use it as a jewelry scale for weighing small gems and jewelry pieces, or as a counting scale for pharmaceutical measurements... the uses are endless!

Easy Calibration You'll have no problem at all calibrating this portable balance. You'll just need to pick up a 300 gram calibration weight to get the job done.

Does This Thing Count? You bet it does! All ya need to do is weigh a sample amount of pieces, so the EJ300 can know how much each piece weighs, then start counting. You'll be finished in no time.

Easy To Clean, Sealed Keypad You won't have to worry about dust and dirt getting stuck under and around this scale's buttons...The A&D Newton has an easy to clean membrane keypad with accurately labeled keys for easy weighing.

Liquid Level Indicator This very handy feature helps you quickly and easily get your scale nice and level. A level scale is important for getting the most accurate weight readings.

Checkweighing Feature Make sure ya get your weights just right with this portable balance's checkweighing feature. When ya weigh in this mode, you can set weight limits for the stuff you're weighing. So, if your sample weight is too low, too high, or just right...the Newton will sure let ya know.

Percent Weighing This feature will let ya compare the weights of your samples against a predetermined reference weight. This can be helpful in weight checking, compounding, formulating and more.

5 YEAR MANUFACTURER'S WARRANTY! This compact balance is covered with a 5 year warranty from A&D Weighing against defects in material and workmanship.

Product Questions

Number of questions: 2
What's the real difference in accuracy between this scale and the 120,123? does it use the same or similar internals?

Can you install a USB interface ex EJ-02 and include the needed usb cable? I am not sure what cable it needs. I just want to be able to plug it in to a pc and have the weight enter into excel when I hit print. Thanks

You can order the optional interface at the same time you order the scale. If you would like the interface installed prior to shipping, you'll need to specify that when you place your order. The cables are sold separately.
