With over 100 years of calibrating test equipment between us, the Labcal Team has the knowledge and experience to calibrate just about anything.


We have extensive experience in providing professional calibration services to businesses across a wide range of industries including: pharmaceutical, meteorological, utilities, electronic, oil , gas and defence companies to name but a few.


Labcal offers calibration over a wide range of parameters that are accredited to UKAS standards and to ISO 17025, which covers the general requirements for competence of calibration laboratories.


We offer impartial calibration and accreditation so suppliers can be assured they have the highest quality control for gas flow, liquid flow, pressure, air velocity, humidity and temperature parameters.


Labcal’s accreditation can be found on the UKAS website. Our Laboratory number is 0625, see our schedule here.

Accreditation by UKAS means that Labcal’s calibration laboratory, together with their certification procedures, have been assessed against internationally recognised standards to demonstrate their competence, impartiality and performance capability.

Labcal is accredited by UKAS to the ISO/IEC 17025: 2017 standard. ISO 17025 is applicable to all organisations performing calibrations. This includes laboratories where calibration forms part of inspection and product certification. It is particularly useful in developing management systems for quality, administrative and technical operations. Laboratory customers, regulatory authorities and accreditation bodies may also use ISO17025 to confirm the competence of laboratories.
