Based in North Wales, we provide calibration services for electrical measurement instruments across the UK and Ireland. Our calibration technicians have years of calibration experience, ready to meet your requirements.
We provide three different types of calibration services, Basic Calibration, Express Calibration and On-Site Calibration. Is your instrument(s) due its annual calibration? We are here to help!
What is Calibration?
Instrument calibration is one of the primary processes used to maintain instrument to a standard of known accuracy. Calibration is the process of configuring an instrument to provide a result for a sample within an acceptable range. Eliminating or limiting factors that cause inaccurate measurements is a fundamental aspect of instrumentation design.
Traceability of calibration
To provide confidence in the legitimacy of the calibration results they must be traceable. This means that the results on the instrument calibration certificate need to be traceable to the standard used, and the results on the certificate for the standard are in turn traceable to the standard used for its calibration, and so on back to standards held by a national laboratory (National Physical Laboratory – NPL in the UK). Furthermore, each set of results in this unbroken chain should be accompanied by a quantified statement of the uncertainty of measurement.
Uncertainty of measurement
There will always be an element of uncertainty about any measurement no matter how carefully the measurement is made. If the measurements are carried out as part of a calibration, then the uncertainty should be reported on the resulting certificate. You can think of the uncertainty as the accuracy with which a measurement has been made.
Do my instruments need calibrating?
Not necessarily, but if your test equipment isn’t measuring accurately then you won’t receive correct measurement readings. Calibrations can be costly and that is one of the main factors when it comes to deciding not to calibrate your instrument(s). However there can be even bigger costs when it comes to using an un-calibrated instrument such as product re-calls, how does the cost of a product recall stack up against the cost of calibrating an instrument(s).
