Teledyne Hastings Instruments (THI) VT-Series Vacuum Gauges are the original models that have generated repeat customers for over 60 years.
Their reputation is built upon exceptional stability, accuracy, and reliability under the most demanding conditions. VT-Series Vacuum Gauges are available in three standard 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. 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. Tubes are matched and interchangeable without calibration adjustments. They are compensated for temperature and rate of temperature change and are corrosion-resistant.
THI Vacuum Controllers, CVT series are fully automatic, continuous-reading instruments for unlimited vacuum applications. These controllers operate in the same standard ranges as the VT meters with the addition of double user selectable control limits. The control points are durable 5 amp single pole double throw relays which can be configured normally open or normally closed.
THI offers a complete line of system attachments that permits easy maintenance for contaminated operations. Gauge tubes are offered with various system fittings to match almost any system requirement.
