Low Vacuum Capsule Gauges
Capsule dial gauges for measuring modest vacuum relative to atmosphere in dry air and gas systems. The finer negative-pressure scale helps where a standard −1 bar dial is too broad.

Overview
Capsule dial gauges for measuring modest vacuum relative to atmosphere in dry air and gas systems. The finer negative-pressure scale helps where a standard −1 bar dial is too broad.
Selection and installation
Use this family for dry gases and specify the normal operating depression. Ask about alternative scales, 316 stainless steel wetted parts or IP65 options if the installation needs them.
Questions about this instrument
Is this the same as a 0–25 mbar absolute capsule gauge?
No. This range reads negative pressure relative to the surroundings. An absolute capsule gauge measures residual pressure against an evacuated reference.
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 0–25 mbar absolute capsule gauge and industrial dial gauges. 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.
