DMM, Dekati® Mass Monitor, is a real-time instrument for diesel and gasoline vehicle PM (Particulate Matter) emission measurements. Used either with a tailpipe sampling system or existing CVS tunnel it provides second-by-second information about vehicle PM mass and number emission.
Despite the discussed number-based measurement standards the mass emission is still the basis of all regulatory measurements. Conventional PM measurements are based on particulate mass measurement with a gravimetric filter, resulting only in a total, cumulative mass emission. Real-time data from DMM provides second-by-second information about particle total mass during accelerations, decelerations and different speed points immediately during the measurement. In addition to particle mass concentration, DMM also provides information on particle number concentration.
Since the instrument is intended for daily routine usage special attention has been paid for usability issues. Ease of use, reliability and integration to test cell information and data logging systems have not compromised the accuracy and sensitivity of this system. DMM is developed so that the detection limit is as low as 1 µg/m3, time response 2-3 seconds and repeatability is better than with gravimetric measurement.
