Product Details

It Has WeighMeter™ Technology! If you put too much weight, (more than the capacity of the scale) on any scale it can cause permanent damage. Unfortunately, most scales warn you of an overload after it's too late. Luckily this Jennings scale comes with WeighMeter Technology to tell you when you're coming close to the maximum capacity. This will save you from overloading your scale and damaging it beyond repair.

The Protective Cover Does Double Duty! This scale's unique hinged removable protective cover is great for keeping your scale safe when you aren't using it...and it doubles as a nice expansion tray, increasing the area you have to weigh your stuff on. Since it has edges, you can weigh all kinds of things that might normally roll right off the platform.

Tare Feature The tare button on the front of this digital jewelry 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 you want to use the cover as an expansion tray to weigh your things, or if you want to get separate weights of multiple items.

It Remembers The Last Unit You 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 JSR100 turns on displaying the unit of measurement you were using when you turned it off.

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

Stainless Steel Platform This digital pocket scale has a stainless steel weighing platform to make cleanup a breeze. The edge of the platform has a small lip clear around the perimeter of the scale, which helps keep items you're weighing from rolling off the platform. We have a bunch of customers who weigh beads and other small objects, and they just love this feature.

Bright Backlit Display This digital mini scale has a fancy red, backlit display to help you see your weight readings, even in dim lighting.

Easy Calibration This scale comes factory calibrated and ready to use. Just in case you need to calibrate it, the JSR-100 comes with easy to follow calibration instructions. You'll just need to pick up a 100 gram calibration weight to get the job done.

Man, This Thing Is Small! You won't have to worry about this little digi scale taking up space. It's just under five inches long, and less than an inch thick! You can take this scale pretty much anywhere you want...stick it in a pack, purse, or in your shirt pocket.

Auto-Off Feature If you 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 JSR100 will automatically turn off after a few moments of inactivity, saving battery power and money.

2 YEAR MANUFACTURER'S WARRANTY! If you have a problem with this scale, just send it to Jennings' warranty center in Phoenix, Arizona. They'll fix or replace your scale and send it on its way back to you within a week of receiving it. You should expect your replacement to arrive in about two to three weeks from the day you send the original off. Keep in mind that sometimes Jennings runs out of stock, which can cause a delay in the warranty replacement process.

2 decimal places is great
review-star review-star review-star review-star review-star
Will be using this scale to weigh cappuchino and hot chocolate powders for calibrating a dispenser. Having the 2 decimal places will provide more than enough accuracy. Only knock that I have with this scale is that it self shuts off very quickly and I need to restart it and tare it between every batch. (Need to run 3 different batch sizes for each machine being calibrated.)

So far ... so good.
Purchased based on word-of-mouth recommendation.
Undocumented auto-tare feature is handy.

I use this scale for measuring powder and shot. It easily switches between grains and ounces and has the capacity and calibration to handle both. Product is great, was exactly as advertised, and arrived early. Obviously, I haven't need any customer support, but something tells me if I did, it would be there.
