Overview
Compact dial gauges for equipment panels and installations with limited space. These dry-case instruments provide a simple local vacuum indication without an electrical supply.
Selection and installation
Send the available panel space and a photograph of the existing connection. Check readability as well as physical fit, especially when the gauge is positioned behind a guard.
Questions about this instrument
Can you match an existing panel gauge?
Send the dial diameter, pressure scale, mounting arrangement and thread. Matching the thread size alone does not establish a suitable replacement.
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.
