The Teledyne Hastings Instruments’ HPM 4/5/6 is a hand-held, battery-operated digital

vacuum gauge based on the highly successful VT/CVT-Series of “Hastings Gauges”

which have generated loyal customers for over 50 years. A reputation has been built on

exceptional stability, accuracy, and reliability under the most demanding conditions.

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.

The HPM 4/5/6 is compatible with 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


The qualities that divide a mediocre vacuum gauge from an exceptional one are often

not readily visible. The integrity with which our products are built is something you’ll experience

in use, and appreciate time and again.

Teledyne Hastings Instrument’s thorough design, intelligent construction and proprietary

manufacturing techniques are the foundation of our reputation for excellence. Stringent

quality controls ensure we remain true to that reputation. Our customers know that we

are the vacuum product manufacturer that they can trust today, and in the future. It’s an

accomplishment that we are proud to own.
