A manifold gauge set is specifically designed to measure the pressure in HVAC (heating, ventilation, and air conditioning) systems. This tool consists of gauges that display both high and low pressure readings, allowing technicians to assess the functioning of refrigerants in cooling systems and troubleshoot issues related to pressure imbalances.

Understanding these pressure readings is crucial for diagnosing system performance and ensuring optimal operation. While temperature can be indirectly assessed through the behavior of refrigerants, it is not the primary function of a manifold gauge set. Humidity and volume measurements are not directly related to the capabilities of this instrument. The focus of a manifold gauge set on pressure measurement makes it an essential tool for maintenance technicians in determining the efficiency and safety of HVAC systems.
