About us

AutoCal+ combined more than 50 years of experience and expertise

The AutoCal+ calibration software was developed by Tradinco Instruments. Tradinco Instruments was founded 50 years ago in Berkel en Rodenrijs. We started as a small-scale specialist, in 50 years we have grown into a global player. With an RvA accredited calibration lab, a clean room, our own calibration software and an extensive product range, it is fair to state we are real problem solvers. With customer wishes as our starting point, Tradinco Instruments always goes that extra mile. The AutoCal+ calibration software has been specifically developed as brand-independent calibration software. That makes AutoCal+ unique. The wishes and needs of the customer and the technical possibilities are what drives us in the development of AutoCal+.
