Handheld, battery-powered HPM 4/5/6 vacuum gauge for compatible Teledyne Hastings DV-4, DV-5 and DV-6 thermocouple gauge tubes. Selectable Torr, mbar and Pa units, detachable cable and rugged carrying case support field checks of cryogenic vacuum insulation and other rough-vacuum systems. The gauge tube and fitting must be selected separately for the required range.
Description
Teledyne Hastings HPM 4/5/6 Portable Vacuum Gauge
The HPM 4/5/6 is a handheld, battery-operated digital vacuum gauge for Teledyne Hastings DV-4, DV-5 and DV-6 thermocouple gauge-tube families. Common applications include cryogenic-tank vacuum insulation, refrigeration and HVAC service, transformer filling and maintenance, particle accelerators and laboratory vacuum systems.

The graphical display shows pressure and battery status. The instrument stores the last-used range and unit and uses a detachable gauge-tube cable. A protective cover and carrying case are included in the described configuration.
DV-series thermocouple tubes are calibrated for nitrogen or air; other gases require the manufacturer's correction data. Confirm the tube family, fitting, cable, pressure range, gas and included accessories before ordering. Gauge-tube temperature and overpressure limits depend on the exact tube variant.
