CPSCC220EW Compute-A-Charge 220lb/100kg Semi-Programmable Compact Refrigerant Scale, Bluetooth

This is exactly what I needed. I work with small refrigeration systems and over or underfill just a wee bit can be an issue. My old scale went in 10g steps. Being able to measure in 2g steps is a real blessing. Linking the scale to the wireless valve makes it even more effective in obtaining an exact fill.

The screen will freeze for up to 30 seconds if you operate the scale near a modulating single phase head pressure controller!

I found it to be a good scale

CPS is a great scale Bluetooth works great to
