TG301C is a wide range combination gauge that a Pirani filament and a temperature sensor integrated in a B-A gauge sensor. TG301C can operate and measure from atmospheric pressure to Ultrahigh vacuum (UHV) pressure continuously. The Pirani filament is made of anti-corrosion material and the grid and the collector of B-A sensor can be operated in “Tough mode”™ in the low pressure range. This features ensure the measurement with the high sensitivity and the accuracy maintained in contaminated environments.
