Their réputation is built upon exceptional stability, accuracy, and reliability under the most demanding conditions. VT-Series Vacuum Gauges are available in three stand- ard ranges: 0-100 mTorr, 0-1000 mTorr, and 0-20 Torr. A self-contained gauge circuit is attached to the rear of the direct reading meter. Ail VT-Series Vacuum Gauges feature long life and minimal maintenance. These instruments utilize THI's rugged but sensitive noble métal Thermocouple gauge tubes that are designed specifically for each range. Tubes are matched and interchangeable without calibration adjustments. They are compensated for temperature and rate of temperature change and are corrosion-résistant. Vacuum Controllers THI Vacuum Controllers, CVT sériés are fully automatic, continuous-reading instruments for unlimited vacuum appli- cations. These controllers operate in the sa me standard ranges as the VT meters with the addition of double user selectable control limits.
