Handheld Portable Vacuum Gauge (HPM 4/5/6)

The HPM 4/5/6 features a precision A/D converter along with a microprocessor to measure the thermocouple vacuum gauge tube’s signal output. 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, easy-to-read graphical display. Tubes are matched and interchangeable without calibration adjustments.
