DESIGN FEATURES
The Model HPM 4/6 is a compact, handheld, digital display, battery operated control unit. When combined with the Hastings Instruments rugged thermopile sensors it becomes a vacuum instrument designed for portability and ease of use in applications where AC power is not readily available.

The lightweight control unit operates with a standard 9 volt battery, and is available for display in units of Torr or mbar. Additionally, it can be calibrated to an individual sensor or set for average sensor output to work with many different sensors of the same type. It is switchable to offer display for both the DV-6 (0.001 to 1 Torr) and the DV-4 (0.01 to 20 Torr) sensors without re-calibrating. These sensors are rugged, noble metal sensors which are resistant to corrosion and
can be ordered with a variety of system connections to meet your system’s requirements such as VCR®, KF 16, KF 25, Glass, MiniConflat™, etc.

The instrument is packaged in a handy, lightweight, rugged carrying case and comes complete with one 9 VDC battery.
