Handheld battery operated digital vacuum gauge. Mbar and Torr reading

The HPM 4/5/6 is a handheld, battery-operated digital vacuum gauge, featuring a precision A/D converter and microprocessor, it measures the output of the thermocouple vacuum gauge tube and converts it to a pressure reading based on the well-defined output/pressure relationship, displayed on a easy-to-read graphical display.

Compatible with three popular gauge tube families DV4, DV-5, and DV-6, these tubes, equipped with noble metal thermocouples, are temperature-compensated, corrosion-resistant, and interchangeable without calibration adjustments.
