Standards we build to

Tell us the standard and accuracy class your project specifies, and we will build to it.

EN 837-1

Bourdon-tube pressure gauges: dimensions, accuracy classes, testing and safety requirements.

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.

  1. Incoming material inspection

    Wetted-part materials are checked against their material test certificates before use.

  2. In-process checks

    Sensing elements, movements and connections are checked at each stage of assembly.

  3. Calibration

    Every gauge is calibrated against a traceable reference standard at several points of the scale.

  4. Pressure and leak testing

    Gauges and seals are pressure-tested to confirm there are no leaks.

  5. Final inspection

    Dial, pointer, window, markings and dimensions are checked against the order.

  6. 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

Tell us which documents you need when you enquire, so they are included in the quote.
