  • Description



Poly Run Digital Vacuum gauge combined thermocouple sensor technology with advanced electronics for precise readings and repeatability not found with thermistor sensors or analog meters. The result accurate readings from atmosphere to 1 micron without recalibration on job after job.

Thermocouple technology has long been proven in laboratory and precision industrial instrumentation for sensing the deep vacuum range. The thermocouple sensors are factory calibrated and exhibit few of the electronic variances of thermistor sensors tound in many other electronic gauges.
