Servicing & Calibration

All of our products are designed to be accurate and durable. Used correctly, each instrument is capable of providing many years of service. However, as with all scientific instruments, they should be treated carefully and serviced periodically.

'The apparatus shall be calibrated after manufacture and recalibrated at least annually and when verification demonstrates non-conformity.'

BS EN 13036-4:2011 (Method for measurement of slip/skid resistance of a surface: The pendulum test)

We recommend servicing your equipment on a yearly basis. Failure to do so may impact the validity of your results and the lifespan of your instrument. We offer a fast turnaround, ensuring minimal disruption and downtime. Continue reading to find out more.

We offer a comprehensive repair, calibration and certification service. This can be tailored to your individual requirements, but a typical service would consist of the following:

  • A thorough inspection of your instrument to ensure that it is free from damage and/or contamination. Any repairs/new parts that may be required will be identified at this stage.
  • Communication with the client to explain the nature and cost of the service. We will always request your authorisation before proceeding with repairs.
  • A pre-certification check to ensure that your instrument is calibrated correctly and meets the required standards.
  • Certification of your instrument:
    1. Portable Skid Resistance Testers are certified by the British Standards Institute (BSI) in accordance with BS 812-114: 1989, BS 7976-3: 2002 and BS EN 13036-4: 2011.
    2. All other instruments are certified internally. A UKAS-traceable calibration certificate is then issued.
  • The safe return of the instrument to your premises.


Should your instrument become damaged for any reason, please contact us for advice. We offer an in-house repair service.
