We offer accredited calibration for temperature, humidity, negative and positive pressure and differential pressure. The calibration services cover instruments and sensors of all makes.

Most calibrations are done in our own fully equipped laboratory in Gothenburg. The lab is staffed by skilled and experienced calibration engineers. If you can’t be without your measuring equipment or if it might be difficult to dismantle, we can calibrate the equipment on site instead.

In addition to our accredited calibrations, we also perform accurate calibrations for quantities such as air velocity, air flow, different gases and so on. And together with lab partners like Testo Industrial Services, we can offer ISO calibration and accredited calibration on over 100 measurement quantities.

We have made it easy for you to keep track of your calibrations. Just scan the QR code that we put on your instrument after we have calibrated it and you will see your proof/certificate on your phone.
