Review on VIVOHOME 220LB HVAC Electronic Digital Refrigerant Charging Weight Scale – High Precision with Protective Case by Tyrell Hudson

Much more accurate than the replacement CPS. I compared both a used battery in an old one and a fresh one in a new one. 10% lower CPS when using tare values on an empty recovery tank. VIVO straight into the money. Batteries changed and weighed again. Both readings now match exactly. Very upset that I have continued to use a buggy CPS all these years. It is important to regularly check the accuracy of the scale. Lesson learned.
