RELIABLE, EFFECTIVE
The dPM-RT is the tool that ventilation officers and workshop staff need in order to reliably identify high DPM emitters, and to validate the effectiveness of emissions related maintenance.

ACCURATE MEASUREMENT
The rugged, practical and easily operated DPM analysis instrument was specifically designed for measuring particulate concentrations in the exhaust of mining engines. Using advanced laser light-scattering technology, the dPM-RT can accurately and instantly measure particulate mass concentrations in the exhaust from all engine types.

RAPID RESULTS
The dPM-RT has been pre-programmed to measure particulate mass emissions during a Stall Test or Free Acceleration Test in as little as just one minute. Internal software guides the operator through these standardised DPM test procedures, collects and processes the test data, and automatically produces an overall result immediately once the test is completed.

SIMPLE OPERATION
The instrument is highly automated, with only a single press-button required to initiate and run a test. It is designed for ease of use by maintenance personnel as an everyday workshop tool, after only minimal training, but retains the flexibility to support more complex research or investigative activities. Routine maintenance of the dPM-RT is limited to checking and periodically replacing one disposable filter.

WHY SHOULD I CONDUCT DPM MEASUREMENTS?
Diesel vehicles are one of the major producers of fine particulate pollution, which is linked to the incidence of severe lung and heart disease. The World Health Organisation has declared diesel particulate matter to be a Class 1 carcinogen – the highest risk factor category. In the confines of underground mining, where diesel engines are the dominant source of mobile power, this issue has even greater relevance and importance. Fortunately, good maintenance can greatly reduce particulate emissions – by up to 80% in some cases.
