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! Not only does the hinged protective cover keep this scale's weighing sensors safe while it's not in use, but also slides off to be used as a weighing tray.

Tare Feature The tare button on the front of this small 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 JSR ECO 400 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.

Bright Backlit Display The JSR-ECO pocket scale has a bright, red backlight that you can turn on and off with the press of a button.

Easy Calibration This pocket scale comes factory calibrated and ready to use. Just in case you need to calibrate it, the JSRECO-400 comes with easy to follow calibration instructions. You'll just need to pick up two calibration weights to get the job done.

This Thing Is Small! You won't have to worry about this little digi scale taking up space. THe JSR-ECO has a small, lightweight design making it perfect for taking it where you need it.

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 JSR400 will automatically turn off after a few moments of inactivity.

2 YEAR MANUFACTURER'S WARRANTY! If you have a problem with this pocket 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.
