Calibration Laboratory.

At our Birmingham based Calibration Laboratory, our team of experienced calibration technicians perform comprehensive calibration services on a variety of metrology equipment including torque, pressure, electrical and temperature devices and mass weights, all using state-of-the-art calibration equipment.

Calibration laboratory for mass weights.

Our mass calibration laboratory is accredited by UKAS to ISO/IEC 17025:2017 to calibrate mass weights.

Our highly trained calibration technicians can calibrate F1 and F2 mass weights from 1mg to 20kg, and M1 mass weights from 1mg to 25kg, using state-of-the-art mass comparators. Our mass weight calibration service also covers the reporting of convention mass, expanded uncertainty and traceability in accordance with ISO/IEC 17025:2017 requirements.

Our mass calibration laboratory will provide you with a UKAS calibration certificate, traceable to national and international standards, which shows the results from your mass weight calibration, including any uncertainties and other information required by the standard ISO/IEC 17025:2017.

If your mass weights are out of tolerance, our calibration technicians can make weight adjustments on-site at our calibration laboratory.

Calibration laboratory for force proving devices, load cells and other force measuring devices.

Our force calibration laboratory is accredited by UKAS to ISO/IEC 17025:2017 to carry out calibrations in both tension and compression of force proving devices, load cells and other force measuring devices in the ranges of 2.2N to 356N, 0.04kN to 11kN and 5.5kN to 500kN using three highly accurate deadweight machines.

Force calibrations can be performed in accordance to BS EN ISO 376:2011 and ASTM E74-18 as well as to customer-specific calibration requirements.

All our force calibrations are carried out using the 1:1 deadweight method, without the use of levers or other force magnification devices. This provides the most accurate method of force calibration and is traceable to national and international calibration standards.

With nearly 50 years of experience in the calibration of force proving devices, load cells and other force measuring devices we are able to apply a world-class level of expertise to the calibration of a wide variety of devices, including highly specialised and unique equipment.

In addition to the laboratory’s force calibration capabilities, we are able to offer accredited testing of loadcells up to 50 tonne capacity to OIML R60 Edition 2000 (E). We have full climatic chamber facilities covering the -10ᵒC to +40ᵒC temperature range, and the associated humidity-cycling facilities.

Calibration laboratory for electrical measurement equipment.

Regular calibrations of electrical testing equipment ensure that the device is performing properly and conforming to manufacturer’s specifications.

Our calibration team can carry out calibrations on a range of electrical testing equipment, including multimeters (up to 5.5 digits), process calibrators, insulation testers, clamp meters, panel meters, voltage indicators and proving units.

All calibrations take place at our calibration laboratory in Birmingham, using market leading Fluke 5520A multi-function calibrators.

Calibration laboratory for pressure equipment.

Our calibration laboratory is able to carry out pressure gauge calibrations to both EN 837-1:1998 and EN 837-3:1998 standards.

Our calibration team use the latest pneumatic and hydraulic pressure testing equipment to provide extremely accurate calibration results for vacuum gauges, pressure gauges, digital pressure indicators, pressure manometers, pressure transducers, pressure sensors, and pressure transmitters.

Calibrations take place using multiple pressure test pumps (both pneumatic and hydraulic), along with highly accurate digital reference gauges (with an accuracy of up to 0.02% of the measurement range).

Pneumatic pressure testing is carried out up to a maximum of 2,900psi (200 bar). All tests over that range take place using hydraulic testing equipment which is carried out up to a maximum of 60,000psi (4,200 bar).

The pressure equipment listed above can also be calibrated through atmospheric pressure testing. Due to the accuracy of the test equipment, this type of calibration provides very small uncertainties on all measurements.

Calibration laboratory for temperature equipment.

We offer calibrations on a range of temperature measuring equipment, including thermometers, thermocouples and temperature instruments. All temperature equipment calibrations carried out in our calibration laboratory are performed using state-of-the-art metrology wells and highly accurate reference probes.

Our team are able to calibrate a range of temperature probes, including thermistors, base metal and noble metal thermocouples, and 2,3 and 4 wire PRTs. Using the metrology well calibration method, probes can be calibrated over a temperature range of -45ᵒC to +660ᵒC.

Our calibration laboratory is also equipped to calibrate a range of temperature equipment using an electrical simulation process, including, digital thermometers, temperature controllers (with both calibration and digital read outs), and temperature indicators.

The calibration of all temperature measuring equipment is traceable to national standards.

Calibration laboratory for torque equipment.

Our calibration laboratory can offer calibrations of torque equipment to both the EN ISO 6789:2003 (withdrawn) and the new EN ISO 6789:2017 standards. We calibrate all brands of torque wrench, up to 2500 N.m.
