A precision A/D converter along with the microprocessor

measures the thermocouple vacuum gauge tube's signal output,

converts the measurement to a pressure reading employing

the gauge tube's well-defined output/pressure function,

and transmits the result.

These instruments are packaged in a small extruded aluminum

case with controls and D-connector mounted on the top cover.

The Digital AVC Vacuum Gauge Meter is available for two of

THI's most popular gauge tube families: the DV-6 and the DV-4.

The DV-6 range is 1-999 mTorr. The DV-4 range is 0.02-20 Torr.

These tubes utilize THI's rugged but sensitive noble metal

thermocouples that are designed specifically for each range.

Tubes are matched and are interchangeable without calibration

adjustments. They are compensated for temperature and rate

of temperature change and are corrosion resistant.
