How Does a Refrigerant Scale Work?

A scale works by weighing the amount of refrigerant that is released into a system.

All HVAC equipment will have a rated amount in pounds how much refrigerant it can hold.

This amount needs to be exact for the equipment to operate correctly.

Weighing a tank and watching a scale will give the exact amount of refrigerant that has gone into an HVAC system.

This is done by setting a tank on the scale, attaching it to a manifold gauge set and letting refrigerant into the system.

If you are an HVAC tech looking for a good basic and accurate digital refrigerant scale for charging and recovery, there are many available.

With the many available, be sure to shop around for one that fits you.

If you are a professional HVAC tech finding a unit that is durable and lasts a long time with accurate readings will be best.

If you are a DIY homeowner or part-time tech, a budget unit may be a better option and cost less.

    I had a fieldpiece scale years ago. I threw it off of a 50 story building. NO JOKE. Every time I need to weigh in a lot of refrigerant the scale will power off on its own. Then my refrigerant continues to charge into the ac system while my scale is turned off. So I have to stand there and stare at the scale. An ex coworker has a fieldpiece scale and he said he has the same problem. Oh yea also in the middle of charging the wireless remote looses connection with the scale. Sometimes to re-sync the scale was a pain. Not to mention it forgets where it left off. Did fieldpiece correct these issues?
