Vak-Check Vacuum Gauges
For proper evacuation and dehydration of refrigeration and air
conditioning systems, an electronic vacuum gauge is an indispensable
companion to a vacuum pump. Significant dehydration does not occur
until a vacuum of 1000 microns or greater has been achieved. Use
of an electronic vacuum gauge is the only way to determine when
dehydration is occurring and when it is complete.
Thermal Engineering Vak-Checks are precision thermistor vacuum
gauges designed especially for refrigeration and air conditioning
service. They automatically compensate for changes in ambient
temperature and permit continuous monitoring during evacuation.
These instruments are compact, lightweight , easy to use and read
directly in microns on a large easy-to-read meter.
