Product Details
  • Man, This Thing Is Tiny!

    You won't have to worry about this 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 ya want...stick it in a pack, purse, or in your shirt pocket.

  • Bright Backlit Display

    The JSR50 has a fancy red, backlit display to help ya see your weight readings, even in dim lighting.

  • Easy Calibration

    This pocket scale comes factory calibrated and ready to use. Just in case ya need to calibrate it, the JSR-50 comes with easy to follow calibration instructions. You'll just need to pick up a 50 gram calibration weight to get the job done.

  • Does This Thing Count?

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

  • It Has WeighMeter™ Technology!

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

  • The Protective Cover Does Double Duty!

    This tiny scale's hard protective cover is great for keeping your scale safe when ya aren't using it...and it doubles as a nice weighing tray. Since it has edges, you can weigh all kinds of things that would normally fall right off the platform.

  • Tare Feature

    The tare button on the front of the JSR pocket 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 the cover as a tray to weigh your things, or if ya want to get separate weights of multiple items.

  • Kill Those Vibrations With VibraKill®

    Did ya know that vibrations can cause a scale's reading to bounce around from one weight to another? Included with this mini scale is a VibraKill® Pad to keep vibrations, (caused by everyday items like, your fridge, nearby music, your washing machine, etc...) from messing up your weighing.

  • 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 JScale JSR-50 turns on displaying the unit of measurement you were using when ya turned it off.

  • Energy Saving Auto-Off

    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 JSR50 will automatically turn off after a few moments of inactivity, saving battery power and money.


    If ya 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 ya 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.

Almost perfect
My own particular use for this scale is weighing coffee beans for espresso, usually 17 grams. This scale is almost perfect. It's small, so it doesn't take up too much precious counter spac. It's reasonably priced and plenty accurate enough for my needs; I can measure to the point where the last coffee bean makes a measurable difference. It's important to keep as many variables as possible constant when making espresso and the amount of coffee used is one of them. My old scale purported to measure to .1 gram, but I could drop several coffee beans on the scale before it gave a different readout. I like that the cover on this scale can be removed if I choose. The only thing that bugs me is that the feet under the scale are inset more than the on/off button which is located at the outside right edge of the top. As a result, when you push that button to turn the scale on, the scale tips down on the right and lifts up on the left -- it annoys me every time. But this scale has so many positive attributes that I am going to buy a second one for another location.

JScale JSR-50 Precision and Accuracy
I purchased this scale for weighing gun powder. I checked the accuracy and precision of this scale by taking 10 measurements of two accurately measured weights; 2.4970g and 5.0135g. The JScale measured 2.51g and 5.03g respectively with 0.0% variation. I also checked 10 measurements with a 20g weight. The JScale measured 20.00g with a 0.02% variation. These numbers indicate that this is a very accurate and precise instrument. This scale is a good value and I would definitely purchase another one or recommend it to a friend.
