Review on 🧊 Kozyvacu 220 lbs Digital Electronic Refrigerant Charging Weight Scales - Ideal for HVAC/Auto AC Refrigerant Recovery Processing with LCD Display, Backlighting, Free 9V Battery, and Portable Carrying Case by Jessie Ritchie

So close to being great. However, the auto shut off is killing me. Mine is inconsistent. It happened within 8 minutes, more than 10 minutes, usually within 15 minutes. When this happens it really slows down while I'm actively measuring the refrigerant. I could see if there was nothing wrong with the readings. But while he measures the weight? nope The last read reminder doesn't work either. When you put these two things together, charging a depleted system becomes a problem. Most notably, I parked between two heat exchangers and didn't hear the scale turn off. However, the scales are small. Great case. Lots of cord. Just.that is the auto power off feature.
