Congrats. I got free electronic scale last year. Bought some glass front reach in fridges from a guy on eBay and he threw in the scale. It has problems and i seem to be the only person on the farm who can operate it but it does work and can be certified by the county.

And still I use the non electronic scales far more often as they are just as accurate. For market I have used an old fashioned hanging scale. until last year it had not been certified but it was sealed by the county weights and measures guy when he visited the farmers market. I had been told for years that non electronic scales could not be certified but was told by the W&M guy that is not true-as long as the scale is made for commercial use (i.e. no baby scales or postage scales) it can be certified and sealed as long as it is weighing accurately (or can be fixed to do so)
