Your service package for warranty services without time limit

After 12 months of manufacturer's warranty does not have to be the end...

To ensure a maximum availability of your products, we are offering you a service package, that includes a guarantee non-stop - the METRA-Check service contract. This provides you calculable annual operation costs, permanent product quality as well as an increasing life of your product. You

r tested device is always up to date and meets the requirements regarding DIN EN ISO 9000 and DGUV regulation 3 (if necessary).


The METRA-Check service contract starts with the end of the guarantee period. At this stage, the annual fee which depends on the device type will be due.

We guarantee price stability of 2 years for the annual fee.

  • DGUV regulation no. 3 security check (without protocol)
  • Update of device-firmware (if necessary)
  • Repair (if necessary)
  • Excecuting a calibration incl. creation of a certificate
