Get diesel emissions test readings quickly with the Hofmann DSS 10, which can develop with you to become a diagnostic information centre for the modern garage.

The wireless DSS 10 provides fast and accurate testing of diesel emissions for test procedures.

It preserves battery power thanks to an automatic standby mode which is activated if the unit is left out of the charger and is not in use.

When the unit is put back on the charging station the wireless smoke meter is constantly warmed up and instantly ready for use.
