Their reputation is built upon exceptional stability, accuracy, and reliability under the most demanding conditions. VT-Series Vacuum Gauges are available in two standard ranges: 0-1000 mTorr and 0-20 Torr. A self-contained gauge circuit is attached to the rear of the direct reading meter. All VT-Series Vacuum Gauges feature long life and minimal maintenance. These instruments utilize THI’s rugged but sensitive noble metal Thermocouple gauge tubes that are designed specifically for each range. T ubes are matched and interchangeable without calibration adjustments. They are compensated for temperature and rate of temperature change and are corrosion-resistant. TELEDYNE HASTINGS INSTRUMENTS
