Product Details

Bright Backlit Display This digital scale has a fancy blue, 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 555 comes with easy to follow calibration instructions. You'll just need to pick up a 300 gram calibration weight to get the job done.

The Protective Cover Does Double Duty! This tiny scale's hard 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 would normally fall 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.

Man, This Thing Is Tiny! You won't have to worry about this scale taking up space. It's just over three 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.

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 ProScale 555 turns on displaying the unit of measurement you were using when you turned it off.

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

90 DAY MANUFACTURER'S WARRANTY! If you have a problem with this scale, just send it to ProScale's 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 ProScale runs out of stock, which can cause a delay in the warranty replacement process.

Looks and operates exactly as expected based on the pictures and description. I was happy to buy from Old Will Knott Scales instead of worrying about whether I was getting a counterfeit item from Amazon (a growing problem there) and the price was the same (even if it wasn't, getting a deal on a counterfeit is not any kind of deal)

We are using this scale in engineering lab kits for our undergraduate teaching program. Many of our students are remote, so this was an affordable and accurate option for various hands-on components to the curriculum.

I bought this to measure resin and it is perfect! I dont need a big one as i don't really do big projects, so i liked that i could that the size of this was great for my little cups. And since the fraction of grams matters a lot when measuring small projects this was able to just what I needed.

Just what I needed, l make herbal teas and sometimes the recipe calls for just 1/4 an ounce and there is no way to measure it on a bigger scale. Very nice scale! It arrived quickly too. Thanks!

Great pocket scale. I now have two of them. I keep one in the car and one in my jacket. I use it to count grams and oz. Very accurate for food counting, like measuring 1 oz of french fries and other items where guessing is your only other option.

Good little scale for the price. Disappointed in the auto shut off feature. I wish there were a switch to turn it off and on when needed.

I purchased Proscale 555 to have a portable device that fits in my pocket. I weigh my food portions everywhere; that is how I lost 175 pounds (without surgery) and kept it off. The scale is accurate, and the display is visible withthe lid used s a tray for the food. Thank you. Highlyrecommend for traveling, and the scale slips in a pocket so the batteries are not effected by cold weather. Economical, too.

We purchased this scale the week before our first big trip. My son is almost 2 years old with PKU so everything has to be weighed and measured. This scale was perfect and so accurate! It fits discretely in my diaper bag so now it goes with us where ever we do! Old Will Knott shipped the scale out so quickly, I was so relieved to have it in plenty of time for our trip!

I got the scale to weigh food - am on a diet and don't trust my "judgement"..ha! The 555 is not laboratory grade but for the $$ a darn nice little scale and accurate too! I am an engineer and a stickler for accuracy and have tried to fool the 555 into a false reading and so far it has passed all of my tests. Will definitely come back to Old Will for future needs.
