Product Details

Auto-Off FeatureIf ya have ever had the batteries in something run out because you forgot to turn it off, you'll realize what a blessing this feature is. The JR300 diamond and carat scale will automatically turn off after a few moments of inactivity.

Tare FeatureThe 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 get the weights of separate items.

Stainless Steel PlatformThis 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.

It Remembers The Last Unit Ya UsedIf your application needs weights in the same unit of measurement, (like ounces for instance), it can be a real pain if your scale always turns on ready to weigh in grams. It's a good thing the JR-300 Ruby turns on displaying the unit of measurement you were using when ya turned it off.

Easy CalibrationThis compact jewelry scale comes factory calibrated and ready to use. Just in case ya need to calibrate it, the JR300 Ruby comes with easy to follow calibration instructions. You'll just need to pick up a 200 gram calibration weight to get the job done.

1 YEAR MANUFACTURER'S WARRANTY!When ya get this digital scale, ya need to go over to the Ohaus website and register it to receive a one year warranty.
