Review on Efficient Robinair TIF9010A Electronic Charging/Recover Scale for Slimline Refrigerant Management by Viswanath Lopez

I'm a refrigeration engineer and I use them to hell. They sit on a shelf in vans bouncing around all day and still do an excellent job when needed, which is 1-3 times a day for me. I've dropped it, stepped on it and dropped ladders and such on it, accidentally of course ;-) Solid, durable and accurate. We have many of them in the company and often compare them with each other. BTW Mine was delivered earlier than expected
