When repairing and refilling an air conditioning system, getting the exact amount of coolant in the system right is essential if you want it to work properly. This is where A/C charging scales come into their own. These handy tools work in conjunction with your AC coolant recycling equipment to refill the AC system properly and get it completely correct.
The more accuracy that you can work with when adding the coolant to an AC system, the better it will work, and the less likely it is for anything to go seriously wrong with it in the near future. A/C charging scales are designed to provide a pre determined amount of coolant such as Freon into the system in order to get the system filled up as efficiently as possible.
An A/C charging scale is a tool that is designed to help you to get the right amount of coolant prepared for loading the AC. In general, an air conditioning system will be rated to contain a specific amount of refrigerant in order to work correctly. This is done by weight rather than volume, as this can vary greatly dependent on temperature.
When the refrigerant has been purified correctly, it can be weighed using an A/C charging scale to gauge...
