German Leybold Vacuum Gauge

THERMOVAC TM 101 handheld vacuum gauge with a measurement range of 1200-5•10
-4 mbar. Piezo/Pirani composite vacuum gauge with temperature compensation, suitable for flange mounting. If using the appropriate battery,
TM101 can also operate in a vacuum environment and continuously display pressure over the entire measurement range.
This product features data memory capabilities, allowing for the storage of up to 2,000 measurement data points. Data recorded can be transferred via USB interface.
Transferred to the computer, it also enables real-time data transmission to the computer.
