DC and LF electrical measurements

The majority of industrial processes and instruments rely on electrical measurements

We ensure that electric industry, electrical equipment manufacturers and utility providers have correct electrical measurements to underpin their industry. We maintain the standards, and also make our capability available to industry, NMIs and customers. We sell both the equipment and services that we also use ourselves, so you can be assured they are the best.

We provide traceability to primary standards, and are impartial and independent. We work with national laboratories and NMIs to develop their own standards and calibration services.

We calibrate electrical test equipment for electrical utilities so that they know that it is operating correctly, and ultimately that consumers can trust their bills are correct because their meters have been correctly calibrated.

Electronics and instrument manufacturers from all industries use us for standards tests, but also for specialist advice on the tests and uncertainties required. By providing the data and analysis, not just the result, we enable you to understand exactly how your equipment is performing. We are responsive and understand the need for commercial focus and excellent customer service.
