Digital THERMOVAC Sensor TM 101

The digital compact THERMOVAC TM 101 combines high-quality sensor technology with modern process technology in a handy design. The THERMOVAC TM 101 can operate optionally as a datalogger saving the pressure data during the measurement. Of course a subsequent simple transfer to a PC is possible via a USB. The fully electronic THERMOVAC TM 101 is capable of measuring pressures within the pressure range of 1200 to 5 x 10-4 mbar (900 to 3.75 x 10-4 Torr) (7 decades). By combining a piezo-resistive pressure sensor for the upper and a Pirani sensor for the lower pressure range, the measurements made by the THERMOVAC TM 101 are independent of the type of gas above pressures of 15 mbar (11.25 Torr). Especially noteworthy is the exceptionally long battery life.
