A micron gauge measures the amount of air or ânoncondensablesâ and moisture in a system.

The deeper the vacuum, the lower the amount of air and moisture in any given system.
Vacuum Gauges \ Micron Gauges. Principal of Electronic Vacuum Measurement. As atmosphere is removed during evacuation the ability to transfer heat by conduction to surrounding air becomes weaker and weaker. Therefore vacuum is easily and accurately read with thermocouple gauges with a preheated sensing element.
