Product Details

Auto-Off Feature If 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 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 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.

It Remembers The Last Unit Ya Used If 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 Ruby JR-300 turns on displaying the unit of measurement you were using when ya turned it off.

Easy Calibration This compact jewelry scale comes factory calibrated and ready to use. Just in case ya need to calibrate it, the Ruby 300 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.
