From the online product manual:
The Hastings Instrument’s Digital VT, is a digital readout version of the successful VT-Series “Hastings Gauge” which has generated loyal customers for over 50 years. A reputation has been built on exceptional stability, accuracy, and reliability under the most demanding conditions. A precision A/D converter, with a microprocessor is used to measure the gauge tube’s signal output; it converts the measurement to a pressure reading using the gauge tube’s well defined output/pressure function, and then display the result. The DV-4 range is 0-20 Torr. All VTSeries Vacuum Gauges feature long life and minimal maintenance. These instruments utilize Hastings rugged noble metal TC gauge tubes that are designed specifically for each range. Tubes are matched and interchangeable without calibration adjustments. They are compensated for temperature, rate of temperature change and are corrosion resistant.
