Mass and mechanical measurement

We give industry access to unparalleled equipment and consultancy in mass, force, pressure and density measurement

Our team of experts help a range of businesses and organisations to measure and control mass, force and pressure

Whether it's doctors analysing the flow of blood leaving a patient's heart or a manufacturer investigating the performance of their gas turbines and aerospace engines, we give organisations confidence in their readings, large or small.

We provide a wide-ranging UKAS-accredited force calibration service, using the UK's national force standard machines. This offers our customers direct traceability to national standards.

We develop innovative solutions for accurately measuring mass, force and pressure in our state-of-the-art labs. We are also on hand to help our clients to achieve accurate measurements on-site.
