Portable vacuum gauge by Teledyne Hastings: reliable in challenging conditions

The Teledyne Hastings HPM 4/5/6 portable digital vacuum gauge

Teledyne Hastings products are available from Durham Instruments, such as the HPM 4/5/6 portable digital vacuum gauge. Based on the popular Hastings Gauges that the manufacturer has offered for nearly 60 years, this handheld, battery-operated tool is compatible with three very common Teledyne Hastings gauge-tube families: the DV-4, DV-5, and DV-6. This device has earned a solid reputation for unmatched stability, accuracy, and dependability in challenging work conditions.

Bright, easy-to-read graphic display

This portable gauge works for numerous applications, including cryogenics and vacuum installation, refrigeration and HVAC, power/transformer filling and maintenance, and particle accelerators. Durham Instruments deems it suitable for general manufacturing, aerospace, automation, food processing, forestry, the medical field, the military, mining, packaging, power generation, alternative energy, and transportation.

Notable features include a precision A/D converter and a microprocessor to measure the thermocouple vacuum gauge tube’s signal output. The microprocessor converts the measurement into a pressure reading with the gauge tube’s well-defined output/pressure relationship. A bright, easy-to-read display presents the resulting information. Other important features of the HPM 4/5/6:

• Torr/mbar/Pascal display units
• Battery-status indicator
• Rugged carrying case
• Detachable cable
• Protective covering
• Compatibility with calibration reference tubes

The DV-4, DV-5, and DV-6 use Teledyne Hastings’ rugged, sensitive, corrosion-resistant, noble metal thermocouples, which are designed for each range. These tubes are also matched and interchangeable without calibration adjustments and compensated for temperature and rate of temperature change.

This instrument uses a nine-VDC alkaline battery and can function in temperatures from -18 to 5 degrees Celsius with the supplied battery, or from -20 to 60 degrees Celsius with an alternate lithium battery. The HPM 4/5/6 offers significant advantages for users, such as long battery life, proven dependability, easy installation, and low cost. Teledyne Hastings constructs its solutions with a level of integrity not found in most competitors’ gauges. The unit has a reputation for excellence with its thorough design, intelligent construction, and proprietary manufacturing techniques – and stringent quality assurance keeps these devices effective.
