Product Details

Does This Thing Count? You bet it does! All ya need to do is weigh a sample amount of pieces, so the scale can know how much each piece weighs, then start counting. This is great if you're using the SPJ-303 as a jewelry scale for weighing your precious gems and jewels, you'll be finished counting in no time.

Adjustable Feet To get the most accurate weight readings from this bench scale, it's best to keep it nice and level when weighing. This Ohaus jewelry scale has adjustable feet that twist in and out, so the SPJ 303 can be level wherever you decide to use it.

Easy Calibration This jewelry scale comes factory calibrated and ready to use. Just in case ya need to calibrate it, the SPJ comes with easy to follow calibration instructions. You'll just need to pick up a 30 gram calibration weight to get the job done.

Easy Calibration When you're weighing with high precision scales like this one, even the tiniest breeze can interfere with weight readings. This Ohaus scale comes with a bubble like windscreen to keep out those pesky drafts.

Stainless Steel Platform The SPJ 303 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.

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 items you're adding. This sure is useful when ya want to use an expansion scoop to weigh your things, or if ya want to get separate weights of multiple items.

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