Back

23 lb 6 oz.

Front

What does a graduated cylinder charging device do?

Back

Measures refrigerant by volume for precise refrigerant charging, has a compensation dial for adjusting to the temperature of the refrigerant, and often has a heater to keep the refrigerant temperature from dropping when refrigerant is released into the system.
