Overview
Vacuum dial gauges with a stainless steel case and 316L stainless steel process connection. Dry and filled configurations cover a broad choice of dial sizes and installation requirements.
Selection and installation
State the gas composition, process temperature and cleaning regime. Stainless steel is a material choice, not a guarantee of compatibility with every chemical. Alternative case, contact and certification options should be specified with the enquiry.
Questions about this instrument
Is a stainless steel gauge suitable for corrosive gases?
Compatibility depends on all wetted materials and the actual gas, concentration and temperature. Give Girovac those details before selecting the configuration.
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 analogue vacuum transducers 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.
