Process and instrumentation calibration

Process meters, loop calibrators, data loggers and power analysers.

Instruments for 4–20mA loops, process control and power quality work, calibrated to keep your plant measurements consistent.

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

Instruments we calibrate

  • Process meter
  • Loop calibrator
  • 3-phase logger
  • Electrical data logger
  • Power analyser
  • Tinytag Ultra 2 data logger

Why process instruments need calibrating

Loop calibrators and process meters are the reference tools engineers use to check transmitters, controllers and 4-20mA loops across a plant. If the reference is wrong, every instrument checked with it inherits the error. Data loggers and power analysers produce records that are used for compliance, energy reports and fault investigations, so their accuracy needs to be demonstrable.

How often should process instruments be calibrated?

Annual calibration is typical. Where an instrument is critical to product quality or safety, or is used heavily, some sites calibrate every six months. Your own quality system or customer requirements may set the interval.

What you get back

  • A calibration certificate with the make, model and serial number
  • Results for the functions and ranges checked, compared with reference values
  • A statement of traceability to national standards
  • The calibration date and recommended due date

All work is carried out under our ISO 9001 quality management system. If an audit or contract calls for UKAS-accredited calibration, we can arrange it through our UKAS-accredited partner laboratory.

Common questions

Will your certificates satisfy an ISO 9001 audit?

ISO 9001 requires measuring equipment to be calibrated or verified against standards traceable to national or international standards. Our certificates state that traceability.

Do you calibrate data loggers such as Tinytag?

Yes, including Tinytag Ultra 2 loggers, electrical data loggers and three-phase loggers.

How quickly will I get it back?

Usually within 3 to 5 working days. Drop it at a Calibration Point partner branch or contact us about collection.
