Teledyne Hastings, manufacturer of the original DV-4 and DV-6 thermocouple gauge tubes, produces vacuum measurement equipment with exceptional stability, accuracy and reliability under the most demanding of conditions. These vacuum sensors are calibrated for nitrogen or air, but conversion factors for other gases are available from the factory.
