Product Details

Dual Readings See your weights in grams and any of three other units at once. This pocket scale displays grams at the top and cycles through pennyweights, carats and grains at the bottom. You can also select which secondary mode you want to view using the mode key.

Bright Backlit Display This digital scale has a fancy blue, backlit display to help ya see your weight readings, even in dim lighting.

Does This Thing Count? You bet it does! All ya 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.

Easy Calibration This scale comes factory calibrated and ready to use. Just in case ya need to calibrate it, the Simplex 300 comes with easy to follow calibration instructions. You'll just need to pick up a 300 gram calibration weight to get the job done.

Stainless Steel Platform This mini scale has a durable stainless steel weighing platform to make cleanup a breeze. Unlike gold or silver, stainless steel doesn't scratch easily, and it keeps its shine without rusting or tarnishing.

The Hinged Protective Cover Does Double Duty! This pocket scale's sliding hinged protective cover is great for keeping your scale safe when ya aren't using it...and it doubles as a nice expansion tray, increasing the area ya 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 ya want to use the cover as an expansion tray to weigh your things, or if ya want to get separate weights of multiple items.

Man, This Thing Is Small! You won't have to worry about this scale taking up space. It's just under 5 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.

Auto-Off Feature 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 Simplex 300 will automatically turn off after a few moments of inactivity, saving battery power and money.

2 YEAR MANUFACTURER'S WARRANTY! If ya 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 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 ProScale runs out of stock, which can cause a delay in the warranty replacement process.

Proscale Simplex 300
Bought this to weight coffee shots and it works very well for this purpose. Tares quickly and seems very consistent. Its small and unobtrusive on the kitchen counter, which is great for my needs but may be an issue if someone wants to weight larger objects. Would easily fit in a shirt pocket if one wanted to take it with them. Appears to a very good value for the price and I would purchase again.

Simplex 300 scale
My Middle school and High school science classes LOVE these scales. Labs that took 2 or 3 days to complete with triple beam get done in 1 day. I can get a quick lab in because because we are not spending time sliding counter weights. Plus they are easy to store. And here is a joke I use ..."remember students these balances are TARE-able.....as you can use the TARE function"...that gets groans every time.

Not usefull... at all.
I bought this scale thinking it would actually work. It doesn't... When I turn it on with the platform empty, it reads 0, however as I weight things, I notice the empty weight creep up over time, after weighing 3-4 items, the scale read 3.4g when empty, and when I added a dime to it, the weight was 3.4g over what it should have been... Also the refresh rate of the display is about once a second, so don't expect any fast measurements out of it, and the weight tends to vary by .2-.3g while the item is being weighed. I've used 2 other centigram scales, and a .1 milligram scale, this is by far the worst I've ever seen, the .1 milligram Ohaus analytical balance without the windscreens provided more stable measurements that this. Definitely go with an Ohaus or Jennings instead of this, the J-Scale is even smaller too.

We know you have a choice when you buy scales online. Just know that when you buy digital scales from Old Will, it's always a "Worry Free Deal".
