The 800 Series Thermocouple Vacuum Gauge Controls are used for repeatable, stable pressure measurement in the 10 -3 Torr to 2 Torr range. These controls are fully temperature compensated by use of a thermistor placed in the gauge cable socket. The thermal response of the thermistor is equal to, but in the opposite direction from the thermocouple characteristics, thereby compensating for ambient temperature changes.
The 801 Control is compact and lightweight, with three mounting studs to facilitate panel mounting in a minimum of space. The 802A is mounted in a portable enclosure. The 801 and 802A have easy-to-read meter scales, recorder output, and include a 10 ft. gauge cable and one 531 thermocouple gauge tube. It also includes a 6-ft. power cord. All necessary cables are included.
