25 years ago the first generation of electronic PREMET® devices was introduced and it started the success story of the PREMET® Diesel Performance Analysers.

Repairs and calibration for the 1st generation have become very difficult or impossible and a design fault on the PCB does not allow a reliable calibration anymore.

Therefore CMT will stop to support these devices with effect from now. We urge every user of these devices to get in touch with us to discuss how to proceed.
