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.

The Model 200 and all other wide-range thermocouple gauges rely on convection (a form of thermal conduction) to achieve their wide range with a thermal sensor. As such, they are sensitive to the gas species.The Model 200 is powered by 115 Volts AC.

Vacuum Rubber Tubing

Pure red gum rubber tubing with cloth impression finish.

The tubing to be used in a vacuum system should be chosen with great care.

This tubing is of high grade, pure gum red rubber, especially selected for its very low vapor pressure, uniformity of wall thickness and excellent sealing properties. It is flexible, yet the extra heavy wall is rigid enough to avoid collapsing under vacuum.

Inside diameters range from 3/16″ to 1 5/8″.

Appropriate size tubing clamps are also available.

Cost savings are offered for 10 foot lengths and up.
