- 0 to −1 bar gauge
- Dial diameter
- 40, 50, 63 or 80 mm
Liquid-filled Vacuum Gauges
A glycerine-filled dial gauge for vacuum installations where vibration makes an unfilled pointer difficult to read. Several dial sizes allow the gauge to be matched to the available space.

Overview
A glycerine-filled dial gauge for vacuum installations where vibration makes an unfilled pointer difficult to read. Several dial sizes allow the gauge to be matched to the available space.
Selection and installation
Tell us about vibration, the process gas and the installation temperature. Confirm the accuracy of the chosen size rather than applying the best range-wide figure to every instrument.
Questions about this instrument
What does the liquid filling do?
It damps pointer movement and helps make the indication easier to read. It does not turn a relative-pressure gauge into a high-vacuum instrument.
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 industrial dial gauges and 0–25 mbar absolute capsule gauge. Check the pressure reference, measurement range and output rather than selecting by connection alone.
Where could this instrument be useful in a vacuum system?
Consider the required local vacuum indication when specifying the INDUSVAC centralised vacuum system or a SIRELLA dry-claw pump installation. Select the measuring range and pressure reference for the process, then confirm the connection and all wetted-material requirements. These links help plan an installation; they do not establish a direct-fit replacement.
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.
