What does an HVAC technician use to measure temperature and pressure?

A manifold gauge set is specifically designed for HVAC systems to measure both temperature and pressure within refrigeration systems. This tool typically consists of two pressure gauges, one for measuring high-side pressure and another for low-side pressure, along with hoses for connecting to the system. Additionally, manifold gauge sets can often be equipped with thermometer probes or temperature readings that allow technicians to measure the temperature of the refrigerant and the air temperature in the system. This combination of pressure and temperature measurements is crucial for diagnosing issues, charging systems, and ensuring proper system performance.

While a digital thermometer is effective for measuring temperature alone, and a pressure gauge can measure just pressure, they do not provide the comprehensive assessment needed for HVAC systems that a manifold gauge set does. A thermal imaging camera provides useful visual information about temperature variations but does not directly measure pressure, making it less relevant for this specific task. Thus, the manifold gauge set is the most appropriate tool for the dual function of measuring temperature and pressure in HVAC applications.
