Teledyne Hastings Instruments
The VT-Series Vacuum Gauges by Teledyne Hastings Instruments (THI) have a strong reputation among customers for being stable, accurate and reliable even under the most demanding conditions, with long operating life and low maintenance needs. These units are available with ranges of 0 to 100, 0 to 1,000 mTorr and 0 to 20 Torr and feature self contained gauge circuits (attached to the back of the direct reading meter). They are based on THI’s rugged but sensitive noble metal TC gauge tubes, specifically customized for each range. These tubes can be easily matched and exchanged without needing calibrations, and feature temperature rate and temperature change compensation as well as excellent corrosion resistance.
