Displayed weight and automatic valve control are different capabilities. Check every scale-only and valve-inclusive package separately.
HOW TO CHOOSE
What matters for the work
Match capacity and resolution
Consider the complete cylinder weight, the required charge measurement and the published resolution.
Choose a reliable viewing arrangement
Decide between a corded handheld, wireless display and app integration according to actual access on the job.
Confirm automation components
A connected scale alone is not an automatic charging kit. Compatible valves, receiving devices and instructions are additional requirements.

SR47 Wireless Refrigerant Scale
Best for: Technicians who want tank-weight measurements within a compatible connected workflow.
SR47 connects refrigerant weight with the Fieldpiece measurement workflow. Select it for that organization of readings, while keeping cylinder limits and charging decisions separate from the display.
Job Link weight monitoring: Refrigerant weighing. A scale does not by itself provide an automatic charging valve or prevent cylinder overfill. Compare this configuration with the alternatives below and price the accessories needed for your actual jobs.

SRS1 is the simpler weighing alternative when remote viewing is unnecessary. Required cylinder weight and measurement resolution decide whether that simpler arrangement is sufficient.
Simpler local weighing: 110 lb. Its 110 lb capacity must cover the actual cylinder and contents. Compare this configuration with the alternatives below and price the accessories needed for your actual jobs.

CC220 Compute-a-Charge Scale
Best for: Technicians preferring a platform with a physically connected handheld display.
CC220 is a straightforward weighing alternative without relying on a phone. Its physical display connection can be useful when dependable local viewing matters more than integrating an app.
Corded display alternative: 220 lb / 100 kg. CC220 is not the programmable solenoid-control configuration. Compare this configuration with the alternatives below and price the accessories needed for your actual jobs.
