Product Details

Rubberized Finish Jennings gave this precision scale a rubberized coating for an extra secure grip to help prevent accidental drops.

Does This Thing Count? You bet it does! All ya need to do is weigh a sample amount of pieces, so the TB500 can know how much each piece weighs, then start counting. You'll be finished in no time.

Bright Backlit Display The TB-500 has a fancy blue, backlit display to help ya see your weight readings, even in dim lighting.

Liquid Level Indicator & Adjustable Feet To get the most accurate weight readings from this precision scale, Jennings designed the TB500 with a liquid level indicator and adjustable feet for adjusting the balance.

Easy Calibration This portable scale comes factory calibrated and ready to use. Just in case ya need to calibrate it, the TB500 comes with easy to follow calibration instructions. You'll just need to pick up a 500 gram calibration weight to get the job done.

Removable Stainless Steel Platform The TB500 has a durable stainless steel weighing platform that lifts right off to make cleanup a breeze. Stainless steel is great because it doesn't scratch easily and keeps its shine without rusting or tarnishing.

Tare Feature The tare button on the front of the TB500 precision 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 a container to weigh your things, or if ya want to get separate weights of multiple items.

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 TB 500 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 TB-500 will automatically turn off after about two minutes of inactivity, saving battery power and money.

20 YEAR MANUFACTURER'S WARRANTY! 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.

In my business, correct weight of the products we sell is essential to maintaining a positive profit margin. The JScale TB500 gives me the confidence to know that our clients will have a positive buying experience every time they do business with us. I've used literally hundreds of digital scales over the past 25yrs. This particular model is the second best I've ever used, and the best value for the money it costs. I highly recommend this to anyone looking for a top-shelf digital scale.

well made scale
Had mine for a couple years now, still works fine. I have a china made scale from ebay that does not detect minute amounts very well. Jennings is very accurate, detects small amounts with smooth fluid accuracy. Worth it.

Great Scale
I bought this to replace two Tree (LM) scales I had purchased from another supplier, which weren't of great quality and performance was very poor. This Jennings scale is SO much better! The size is compact, it was packaged well, has a quality rubberized finish, I didn't have to calibrate it and batteries are included! I've used it three times and so far it works perfectly. I love the built in bubble mechanism that helps level the unit for accurate readings.

My only critique is that the legs on the scale are a little short. I ended up having to place a folded cloth underneath the back legs and it worked perfectly. Also want to mention I got great customer service when contacting Old Will Knott Scales for recommendations for a new scale. I can tell they care about their customers and providing quality products are priority and it's greatly appreciated!

Works great!
I bought this scale for perfume making. I measure very small quantities when creating new scents, and this allows me the needed precision – down to the drop! My only critique would be I wish the capacity was greater so I could use it when I measure larger batches of product of 5lbs, but I have a different scale for that. It arrived quickly and I appreciate the friendly tone in the customer service.

This is the perfect scale for my little archaeology lab, affordable yet highly functional and easy to use. And Old Will Knott made it easy to pick out and buy the right scale for my needs.

Everything is Great
I purchased this scale for making ejuice, I am very well pleased with the product. Due to my own error when ordering, shipping was delayed for a day. When I called customer service, they were friendly, & promptly corrected the issue. Shipping was fast after that !! I will order from Old Will Knotts again in the future.

Nice Scale
The Jennings TB500 is a nice little scale. It is good looking and dependable. The front cover is having some problems with not sticking properly to the scale but it doesn't effect the performance of the scale.

We were hand counting thousands of bottles by hand!
Life is good!!! We are no longer counting our e-liquid bottles by hand, now we are counting hundreds at a time! This scale is just the best, and it paid for itself the first day of use!!! Easy to setup and operate. Adjustable feet, built in level, batteries already installed plus a power adapter too! We will buy a second unit very soon! Buy One TODAY if you are looking for a great scale!
