Imperial 4501 Thermal Thermistor Vacuum Gauge

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 only occurs once a vacuum of 1000 microns or greater has been achieved. Electronic vacuum gauges are the only way to determine when dehydration is happening and when it is complete.

Imperial-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.

• Atmosphere to 10 microns
• Ambient temperature compensated
• Accuracy: 200-1000 microns: ±5%
• Comes complete with a Model 4510 Sensor
