The vacuum gauge combines a piezoresistive sensor for high-pressure measurements with a heat conducting Pirani sensor for low-pressure measurements. This dual-sensor approach makes the TM 201 suitable for a wider range of vacuum applications. It can measure both absolute pressure and relative pressure (-1060 to 340 mbar), thus supporting leak detection and pressure monitoring. The integrated data logger records measurements with a time stamp. Stored data can be easily transferred via USB-C or Bluetooth® LE and analysed with the optional VacuGraph™ software.
