How to Buy a HVAC Refrigerant Scale

By | August 27, 2014

A Refrigerant Scale allows a HVAC technician to measure the amount of refrigerant that is going into a unit accurately by weight.

A scale is used by setting a refrigerant tank on top of it and by weight tell how much refrigerant is in a tank. Some scales are setup so a tank can hang from it rather sit on top of it.

Most refrigerant scales are digital and will measure the progress as the refrigerant leaves the tank and goes into a unit. This gives a technician the information needed to accurately fill a unit and to charge the customer.

Electronic programmable scales can be programmed for the amount of refrigerant a system needs and will automatically turn off when it reaches the set point.

When buying a scale look for sturdiness of the case since it will have to handle some abuse and ideally it will be used for years. Also although more of a personal option buy a scale were the tank sits on top of it rather than hangs, often there will be nothing to hang it from when in the field.
