The Leybold THERMOVAC TM201 is a handheld vacuum gauge with a graphic display and built-in data logging. Use it to record pump-down behaviour or check pressure during service and commissioning.
Select the right measuring range
The TM201 follows a pump-down into fine vacuum. Tell us the gas being measured, since the Pirani part of the instrument responds differently to different gases.
Specify the package
Choose standard or Bluetooth communication, then tell us whether you need a case, charger, connection fittings or calibration documentation. We will itemise the supplied equipment.
Compare portable vacuum meters or discuss calibration.
