Overview
Portable vacuum instruments for service checks, process records and pump-down investigations. Select an integrated sensor or an external sensor where the measuring point is difficult to reach.
Selection and installation
Choose the pressure range first, then the logging and connection requirements. The newer platform offers internal or external sensing; its exact range depends on the sensor, so specify that combination with the enquiry. Send the sampling interval and length of the recording required.
Questions about this instrument
Can a logger help investigate a leak?
Pressure-rise records can support investigation, but rising pressure can also come from outgassing or vapour. Interpret the trend in the context of the process and isolation procedure.
Can I request calibration with my gauge?
Yes. Tell us the operating range, required test points and certificate requirement. We will confirm the calibration option for the selected instrument before quoting. Discuss vacuum gauge calibration.
Which related instruments should I consider?
Compare Pirani vacuum transducers and vacuum gauge controllers. Check the pressure reference, measurement range and output rather than selecting by connection alone.
Where could this instrument be useful in a vacuum system?
Pressure records can be useful when checking a rotary vane vacuum installation or investigating a laboratory freeze-drying system. Choose a sensor suited to the actual pressure and vapour conditions; logging a trend does not by itself establish the cause of a pressure rise.
Specify your requirement
Send the pressure range and reference (absolute or relative), process gas, connection, quantity and required delivery date. Include the existing model or a photograph for replacement enquiries.

Choose a portable meter
For rough-vacuum checks, compare the Leybold PV201 and Thyracont VD810. To follow a pump-down below 1 mbar, see the Leybold TM201 and Thyracont VD850. Each range offers a Bluetooth version.
For a pressure gauge with mobile logging and a specified vacuum or compound range, see the SMBDPG Bluetooth gauge.
