Teledyne Hastings DV-4D Vacuum Gauge

The Teledyne Hastings DV-4D Vacuum Gauge delivers precise rough vacuum measurements from 0.01 to 20 Torr using thermocouple sensing, making it well-suited for monitoring low-vacuum conditions in HVAC and refrigeration service equipment, laboratory vacuum systems, semiconductor processing equipment, transformer oil processing, and other industrial vacuum applications. This genuine Teledyne Hastings vacuum gauge tube features a 1/8 in. male NPT process connection, uses nitrogen or air as calibration gas (conversion factors available for other gases), and is compatible with controllers including HPM-4, HPM-5, HPM-6, VT Series, DVT, DCVT, DAVC, and CVT Series, as well as the DB-16D reference tube. Common replacements include the DV-4R and DV-4D-KF-16 and DV-4D-KF-25.
