Did you ever wish you had electronic scales that didn't have to be calibrated...
weren't sensitive to static electricity or small wind currents...
were as repeatable and more accurate than a balance beam...
and didn't break the bank?
Boy I sure have. But looking at the "real" analytical scales and their prices brought me back to earth. Sure, you can buy an analytical balance that does all that for an arm and a leg. But a guy can dream, right?
Well, my THIRD electronic balance crapped out on me at a critical time. I was working on a load that didn't need super precision so I used the electronic scale to set up my powder measure. But something wasn't right so I double checked on the balance beam and got a 2 grain difference. So I recalibrated the electronic scale and still got a 2 grain difference.
My first reaction was "Well that's it, no more electronic scales! I'm done with them!"
But then I got to thinking, what if there was an analytical scale that didn't break the bank that I could use? And by an analytical scale, I mean one that uses electromagnetic force restoration instead of a strain gauge. The strain gauge is what makes less expensive scales so sensitive to static, temperature, etc. The electromagnetic force restoration scale simply uses an electromagnet to support the weight, and when the weight is supported, it uses the current required to calculate the weight.
I found one scale by Ohaus that seemed to fit the bill but there were two problems: 1) it didn't weigh in grains and 2) the reviews were not so great.
Then I found what one of those "too good to be true" things...an analytical scale that used magnetic force restoration that didn't break the bank...AND...the reviews were really good.
It arrived TODAY.
First thing I did was make a space for it and set it up. Each of the four legs is adjustable and it has a level built in, so I got it leveled up, powered it up, and put the 100g check weight on it:
So far so good...no calibration, no warmup just plug it in, turn it on and go.
So next I tared it with the scale pan and threw a charge and weighed it:
Then I weighed it on the balance beam
And for good measure, I emptied the pan and put it back on the scale
Price? $178 with free shipping. Takes a week and a half for shipping.
