APG200 High Performance Compact Pirani Gauge

Edwards new APG200 series high performance compact Pirani Gauge is the perfect vacuum measurement solution across a spectrum of applications due to its compact size, LED light ring, integrated set points and flexibility of connections/outputs.

Low Cost Thermocouple Gauge Controller

Mass-Vac, Inc. offers a compact, low cost wide range thermocouple vacuum gauge controller that uses a highly visible LED display. (760 to .001 torr range.) This unit is packaged in an attractive and rugged case. It comes with power cord, cable and 531 type tube. Plugs directly into 115 V AC.

Model 200 uses a sophisticated, microprocessor-based circuit to measure from atmosphere to hard vacuum using a rugged, inexpensive, thermocouple vacuum gauge tube.
