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 JSR150 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-150 comes with easy to follow calibration instructions. You'll just need to pick up a 100 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 Technolgy 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-150 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 JSR150 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.

Great Little Scale
Great little scale, does everything that I wanted. Worked fine right out of the box. The website was also excellent is helping me select the right scale for my needs. Highly recommend both the scale and Old Will Knott!

Uses standard batteries
This scale uses standard AA batteries, unlike some other scales that use expensive round "coin" batteries. It's so handy to have around the house, we just purchased three more!

The price point on this scale makes it a great deal. Compact, calibrated, ready for use, and accurate. I have recommended this scale to friends.

Perfect portable scale
Good portable scale, with flat surface that makes it easy to measure items that could hang over the edge.

Q: Hi, I am making a cream and my kitchen scale would not register 0.15 grams of the product. Will this scale go that low? Thanks, Deb

Asked by:  (Submit an answer)

A: Hi there Deb,
No, the JSR-150 only goes down one decimal place past zero. (0.1 grams) I would recommend the Triton T2 200. That has a resolution of 0.01 grams, enabling it to weigh the 0.15 gram weight value you're looking for. Here's a link: http://www.oldwillknottscales.com/my-weigh-triton-t2-200.html
Take care,
