801 | F2739301 Varian Thermocouple Gauge Control

The Varian 801 Thermocouple gauge Control is a compact, self-contained instrument designed primarily for panel mounting. It is supplied with a 6’ line cord and a 10’ thermocouple gauge cable. The instrument is line voltage-regulated, and a temperature-thermocouple gauge socket. The indicator dial, which covers the pressure range from 1to 200 milliTorr (1 milliTorr is 1/1000 of 1 mm of mercury, or 1/1000 of Torr), is calibrated for a Varian 531 thermocouple gauge in dry air. The mechanical zero adjustment is located on the cover (Figures 1a and 1d). The meter voltage (0 to 11. mV) is available attwo solder terminals at the rear for operating remote indicators whose input resistance should be 200 Ohms or more.
