DMS500 Mk2 | Particulate Analyzer

The DMS500 has established itself since 2002 as the particle measurement instrument of choice for engine research, development and calibration, with hundreds of customers worldwide including OEMs, Tier 1s and Universities. Successive generations of the DMS500 have offered improved capabilities and made the DMS500 the most dependable instrument in its class.

Flexible measurements – fit for future development

The DMS500 represents a "turn-key" system. The fully integrated dilution and sample conditioning system allows measurment from from the exhaust port, pre- or post- after-treatment, in the CVS tunnel and even from ambient.

10Hz data and a T10-90% response time of just 300ms even with a 7 metre sample line allow the DMS500 to offers valuable insights into engine operation, even during highly transient cycles such as RDE, NRTC and FTP75.

Particle Mass (PM) for gravimetric regulations and for engine out model development (e.g. DPF/GPF load models).

Particle Number (PN) with a fully characterised thermodilution system including a Catalytic Stripper to remove volatile particles when required. Flexible software allows measurements with a 23nm roll off (Euro 6) or the possible future 10nm roll off (possible Euro 7).

Particle Size distributions (5nm -2500nm) for maximum understanding of combustion behaviour, particle formation and evolution, and the effects of engine controls on PN and PM.

Sub-zero testing capabilities for current and future cycles. The DMS500 can easily make measurements while sampling from ambient temperatures below 0°C.

Developed for daily use – reliable results

Backed by over 15 years of continuous development, the DMS500 is straightforward to operate even for inexperienced users.

Dependable error detection and optional test cell integration allow the DMS500 to be seamlessly added as part of general test cell equipment.

Traceable calibration certificates and automated checks guarantee accurate and repeatable results.
