Traceable Calibration

All our calibration transfer standards, calibrators, equipment and standards have traceable UKAS current  certificates and are maintained within an environment that maintains the highest accuracy.
Our traceable certificates are available to view if required.

When we quote calibration uncertainty for our equipment it is based on the 1 year figures. Our +/- calibration uncertainty is printed on the table of results issued with every instrument.

Our working environment is maintained at a temperature of 20°C ± 2°C, Humidity RH 40 - 70%. to maintain the highest accuracy from our equipment.

All customer test results are recorded automatically by our calibration software. We use Transmilles Pro Cal software to automatically control our calibration equipment, record readings and provide a comprehensive set of calibration procedures. This helps to reduce any errors in the calibration process.

All customer calibration results are stored for a minimum period of 3 years or 1 year after the next cal due date.

We maintain our UKAS traceable standards are calibrated at regular intervals by a UKAS Laboratory. We then keep all our calibration equipment within a controlled temperature environment to maintain the highest traceability accuracy throughout our range of measurements. Lab temperature and humidity are constantly monitored and logged by a data logger. 


We publish our calibration uncertainties on all our calibration documentation sent to our customers. They are also published on our website for reference purposes.

Electrical Test Equipment

We have invested in state of the art calibration equipment to maintain accuracy and  serviceability. All our calibration equipment has a current UKAS  certificate traceable back to national standards.

Multifunction Testers, Pat Testers, Insulation, Continuity and Earth Testers.          




We calibrate Fluke, Megger instruments and Kewtech range of Multifunction Testers  as well as stand alone insulation, earth loop impeadance and earth ground testers.
We can also calibrate a wide range of PAT testers.


 Fluke 1652C, 1653B, 1654B  

Older models of this range of testers are still supported by us for calibration.  

RF Frequency Source and Reading

We have a  traceable RF frequency capability of up to 1GHz source and 3 GHz reading.

Calibration Procedures

We have a large library of written calibration procedures as part of our Quality Control system, these procedures are used in conjunction with manufacturers specifications and service manuals to carry out the calibration process. Procedures are also held on our calibration software to determine equipment pass and fail limits during test.

Control Documentation

With each instrument calibrated we provide to the customer the following documentation:
  • Certificate of Calibration
  • Engineers Report
  • Calibration Readings +/- Uncertainty values
The documentation above will be delivered with the test equipment including a delivery note.

Instruments will be labelled with a calibration sticker that has the calibration date, due date, equipment serial number and a certificate reference number that links everything together. Tamper proof seals are also used to give an indication of un-authorize tamper.



We use ProCal calibration software to ensure all our procedures and history is stored in a reliable and efficient way.

Safety Checks

We will carry out a visual inspection of all equipment prior to calibration, any defects found will be reported to the customer for further action.
All mains sourced equipment will be subject to a PAT test before leaving our premises to ensure the equipment is safe to use.
