Particulate spectrometer with fast response is for engine calibration and optimization.
- Solid particle counter for compliance with EU regulation
- Particle Mass weighing for compliance with 40CFR 1065
It seems that the particulate matter from vehicle exhaust emissions are one of the environment issue, so that it is especially required to measure the particle size less than 2.5um. Sokken provide a series of particulate instruments such as differential mobility particulate sizer and solid particle counter for compliance with European regulation.
Particulate spectrometer with fast response is for engine calibration and optimization.
The particulate matters(PMs) contained in vehicle exhaust emissions is known as one of the toxic chemical substances for human health and is restricted by the exhaust emissions regulations in adding to hydrocarbon(HC), carbon monoxide(CO) and nitrogen oxides(NOx) components.
The ultra fine PMs (< 0.1um in daiameter) from diesel vehicles seems especially to be affected to the human health and the emissions regulations have recently been strengthened in many countries, as a result that the number concentration and total mass PMs in exhaust emissions have greatly been reduced so that applying the conventional filter paper method for weighing the mass particle matters will be expected to close its limitations.
By this reason, a new method to count the particle number concentration was being studied globally around Europe in adding to the conventional filter paper method and it will be expected to introduce in September 2011 for Euro 5b.
Therefore, an instrument is required to measure particle numbers in diesel exhaust emissions - known as PN.
A new instrument for counting the particle numbers in diesel exhaust emissions is regulated by PMP standard (Particle Measurement Program) in EU and the system should be configured fully compliant with this standard.
