What is the function of an Electronic Vacuum Gauge or Micron Gauge?

The function of an Electronic Vacuum Gauge, also known as a Micron Gauge, is to provide a precise measurement of the vacuum level in the system, displayed directly in microns. This measurement is crucial during the evacuation process of refrigeration systems, where achieving a high level of vacuum is necessary to ensure that moisture and non-condensables are removed. The ability to monitor the vacuum level in microns allows technicians to determine the effectiveness of the evacuation and ensures that the system is ready for refrigerant charge.

While temperature measurement, controlling refrigerant flow, and detecting leaks are important aspects of refrigeration system maintenance and troubleshooting, these tasks fall outside the purview of what an Electronic Vacuum Gauge is designed to do. Temperature levels are typically monitored using thermometers or temperature probes, refrigerant flow control is handled by metering devices, and leak detection usually involves specialized equipment or methods such as electronic leak detectors or soap bubble tests. Thus, focusing on vacuum measurements is the primary and defining function of a Micron Gauge.
