Manifold gauge sets, sometimes called HVAC gauges or refrigeration gauges, diagnose and repair refrigerators or cooling systems. They measure both low- and high-refrigerant pressure with either digital or mechanical gauges to troubleshoot issues such as leaks or to help when evacuating and recharging a system.
Manifold gauges are used to monitor heating or cooling systems, specifically the pressure of refrigerants. These tools are used to control the flow of pressure or gas.
