FIRST weigh in scales
 

Does anyone know the brand and model number of the exact scales the inspectors use at FIRST events?

I assume they are a standard off the shelf brand pallet/floor scale by some company but I have never really payed enough attention during inspection. I am looking for a floor/pallet type scale but don't need a huge one with a capacity of 5000 or 10,000 lbs. and would prefer one of about the size used in FIRST inspections with a capacity between 800-1000 lbs and the best accuracy possible. In other words I would rather have a 2' x 2' 1000 lb capacity scale with a 0.1 lb accuracy than a 4' x 4' 10,000lb capacity scale with 1.0+ lb accuracy. My brief internet searches have turned up a lot of the later but few of the former and then I was thinking of the FIRST scales and wonder if they wouldn't be just about right. Any inspectors out there know the brand/model of scales FIRST uses?

Thanks.

I think this picture I took is from a FIRST competition....

($600 for 1000 lb x .1 lb)

Perfect! Thanks! That led me to here: http://www.arlynscales.com/Platform-...form-scale.htm which is just what I am looking for and at a price that beats most other places I have seen.

This is the info I got from the Lead Inspector at GLR...

Team 228 had two scales donated to us in 2004 from BMS; one was a 150 lb scale and the other was a 400 lb scale. The 150 lb has higher precision, but we normally use the 400 lb since we've found that a lot of students like to stand on them to see how much they weigh. :rolleyes:

I've found the same models on McMaster: 17295T31 and 17295T39.

They are a lot cheaper than the other models, if you don't mind the +/- 0.2 or +/-0.5 lb increments respectively.

Speaking of FIRST scales. Our team we about 118lbs in Manchester. At Chesapeake we added about 2-3 pounds of upgrades and fixes. We were wondering how close it was going to be, but to our amazement, when we put the robot on the scale, it weighed a tiny bit less. Anybody have any idea how this could happen?

Different scales, different floors... It's been said that with several scales, a slightly heavier team would be directed to the "lightest"... Before calibration measures were taken, that is.
