Vacuum Measurement (VT/CVT and DVT/DCVT)

The Digital VT/CVT Vacuum Gauge Meters are available for three of THI’s most popular gauge tube families: DV-4, DV-5, and DV-6. These tubes utilize THI’s rugged but sensitive noble metal thermocouples 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. The microprocessor converts the measurement to a pressure reading by employing the gauge tube’s well-defined output/pressure relationship. The result is displayed using a bright 3-digit green LED display
