What tool is typically used to measure refrigerant pressure in a system?

The manifold gauge set is typically used to measure refrigerant pressure in a refrigeration system. It consists of two pressure gauges—one for measuring the low side pressure and another for the high side pressure. The gauges display the pressure of the refrigerant in pounds per square inch (psi), which is essential for diagnosing system performance, checking for proper charge levels, and identifying any potential issues that may arise.

Using a manifold gauge set allows technicians to safely and accurately monitor the pressures within the refrigerant system, thereby enabling effective troubleshooting and maintenance. Other tools like digital thermometers can measure temperature but do not provide information about the pressure of the refrigerant. Measuring tape is used for measuring physical dimensions and is not applicable in this context, while a pressure cooker gauge is designed for steam pressure and not suitable for refrigeration applications.
