Total pressure displayed directly at the process chamber
The battery-powered handheld measurement units make it easy to display and save pressure values. They are available in two versions. The TPG 201 works on the heat conduction principle (Pirani). The TPG 202 has an additional piezo-resistive pressure sensor for gas-type independent measurement in the upper pressure range. Depending on the device, the handheld units cover a pressure range from 1,200 hPa to 5 · 10-4 hPa.
