Teledyne Hastings Instruments DB-16D Vacuum Gauge

The Teledyne Hastings DB-16D Vacuum Gauge Reference Tube is a NIST-traceable calibration reference used to verify and calibrate thermocouple vacuum gauge controllers and meters in rough vacuum systems. It is designed to work with the DV-4 Series Thermocouple Gauge Tube and supports a 20 Torr measurement range compatible with DV-4 instrumentation. This genuine Teledyne Hastings Instruments reference tube is compatible with HPM-4/5/6, VT Series, CVT Series, DVT, DCVT, and DAVC controllers, and it serves in calibration, controller verification, and preventive maintenance across HVAC and refrigeration evacuation systems, laboratory vacuum equipment, semiconductor manufacturing, industrial process vacuum systems, and research environments. Common replacements include the DB-18, DB-20, and DB-33 reference tubes.
