Service & Calibration

Survey Equipment Calibration


As a manufacturer-approved distributor for a range of brands, we can provide full instrument calibration, including EDM total station servicing and repairs.

The servicing workshops calibrate both customers own equipment whilst ensuring our hire fleet is of the very best standard and accuracy. The workshops use specialist collimation rigs that are regularly calibrated to industry standards.

Product maintenance is crucial for your equipment to continue working effectively over time. Accurate instruments are key tools on construction sites and there are different options available for scheduled maintenance to keep your survey equipment in the best shape.

Our fully equipped workshops allow us to provide fast turnaround support for your equipment right across the UK. We specialise in calibration and repair of survey equipment including total stations, laser levels, rotating lasers and machine control (GNSS).
