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 lightscattering technology, the dPM-RT2 can accurately and instantly measure particulate mass concentrations in the exhaust from all engine types.

Rapid Results
The dPM-RT2 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-RT2 is limited to checking and periodically replacing one disposable filter.

Alerts from the International Agency for Research on Cancer (IARC) have focused public awareness of dangers to human health
from the microscopic carbon-based particles emitted in the exhaust of diesel engines. As a Group 1 carcinogen (the most dangerous
category) the IARC (a part of the World Health Organisation) estimates that these particles are responsible for hundreds of
thousands of deaths around the world each year.

Given the dominance of diesel power sources in underground mining, the industry has clear responsibilities to minimise worker exposure
to this most dangerous pollutant. A capability to effectively monitor and control tailpipe particle emissions is a key component of
these responsibilities. Fortunately, good maintenance can greatly
reduce particulate emissions – by up to 80% in some cases.
Traditional methods, such as measurement of smoke opacity, have been shown to be significantly inferior to the laser light scattering technologies employed in the dPMRT2 which detects and measures
concentrations of particulates with a nominal diameter down to less than 100 nm (0.0001mm)
