Pressure and HVAC instrument calibration

Pressure indicators, digital manifolds and refrigerant leak detectors.

Pressure and refrigeration instruments for HVAC and building services engineers, calibrated so system readings and leak checks can be trusted.

All calibration is traceable to national standards and carried out under our ISO 9001 quality management system.

Instruments we calibrate

  • Pressure indicator <300 mbar (air)
  • Pressure indicator up to 20 bar (air)
  • Digital pressure manifold
  • Refrigerant leak detector

Why pressure and HVAC instruments need calibrating

HVAC, refrigeration and gas engineers make safety and efficiency decisions from pressure readings. Tightness tests, system pressure checks and refrigerant charging all depend on the manometer or digital manifold reading correctly. An inaccurate leak detector can miss a refrigerant leak, which is both an environmental and a compliance problem.

How often should pressure instruments be calibrated?

Annual calibration is the standard expectation for pressure indicators, digital manifolds and refrigerant leak detectors. F-gas leak-checking guidance expects electronic leak detection equipment to be checked at least every 12 months. Recalibrate sooner if an instrument has been over-pressurised, dropped or repaired.

What you get back

  • A calibration certificate with the make, model and serial number
  • Pressure readings at points across the range compared with reference values, or a leak detector sensitivity check
  • A statement of traceability to national standards
  • The calibration date and recommended due date

All calibration is carried out under our ISO 9001 quality management system. UKAS-accredited calibration can be arranged on request through our UKAS-accredited partner laboratory.

Common questions

Do you calibrate low-pressure manometers used for gas tightness testing?

Yes. We calibrate pressure indicators below 300 mbar as well as higher-range gauges up to 20 bar.

Can you calibrate digital refrigeration manifolds?

Yes. Digital pressure manifolds are one of the most common instruments we see from HVAC engineers.

How do I get my instrument to you?

Drop it at a Calibration Point partner branch and we'll collect it. Find a partner branch. Most instruments are back within 3 to 5 working days.
