EN 837-1
Bourdon-tube pressure gauges: dimensions, accuracy classes, testing and safety requirements.
Standards we build to
Tell us the standard and accuracy class your project specifies, and we will build to it.
EN 837-3
Diaphragm and capsule pressure gauges, including low-pressure ranges.
IS 3624
Indian Standard for Bourdon tube pressure and vacuum gauges, when your specification calls for BIS requirements.
ASME B40.100
Pressure gauges and gauge attachments, for projects specified to American standards.
ISO 9001
Certified quality management system covering design, production, calibration and dispatch.
ISO 14001 and ISO 45001
Certified environmental and occupational health and safety management.
Our quality process
Each gauge goes through the same checks, from raw material to dispatch.
Incoming material inspection
Wetted-part materials are checked against their material test certificates before use.
In-process checks
Sensing elements, movements and connections are checked at each stage of assembly.
Calibration
Every gauge is calibrated against a traceable reference standard at several points of the scale.
Pressure and leak testing
Gauges and seals are pressure-tested to confirm there are no leaks.
Final inspection
Dial, pointer, window, markings and dimensions are checked against the order.
Documents and dispatch
Your gauges are packed and sent with the agreed certificates and reports.
Calibration traceability
We calibrate every gauge against reference standards, such as dead weight testers and master gauges. These reference standards are themselves calibrated at regular intervals by an accredited laboratory, so every reading is traceable to national standards.
The calibration certificate records the reference standard used, its certificate number and validity, the test conditions, and the readings at each test point on increasing and decreasing pressure.
Documents with your order
- Calibration certificate, with readings at several points of the scale
- Test report
- Material test certificate (MTC) for wetted parts
- Certificate of conformity to EN 837, ASME B40.100 or IS 3624
- Third-party or customer inspection, when your project requires it
