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

In a refrigerant system, a pressure gauge is used to measure the pressure reference. This instrument provides critical information about the operating conditions of the system, allowing technicians to assess whether the refrigerant is at the appropriate pressure for efficient cooling and system performance. Pressure gauges are specifically designed to read the pressure of the refrigerant, which is essential for diagnosing system issues, managing refrigerant levels, and ensuring the system functions safely and effectively.

In comparison to other tools, a thermometer measures temperature rather than pressure, a manometer specifically measures the pressure of fluids, and an indicator card is used for different types of recording but does not directly measure pressure in the context of refrigerant systems.
