The Engine Exhaust Condensation Particle Counters (EECPC) have a 12-year proven track record for reliability and accurately measuring concentrations to meet the standards of the GRPE Particle Measurement Program (PMP), including Euro 6 Regulations 83 and 49, as well as upcoming Euro 7 regulations.
The EECPCs 3790A and 3790A-10 are fully compliant for light-duty and heavy-duty vehicle certification in accordance with all Euro 6 Regulations 83 and 49 requirements. Built upon the proven rugged, reliable, and highly repeatable performance of the TSI® 2nd gerneration CPC technology, the EECPCs incorporate a wide assortment of design improvements and features such as anti-spill, anti-flooding design, adjustable internal calibration factor, removable saturator for ease of maintenance, built-in microprocessor with USB, RS- 232 and Ethernet communication interfaces, touchpanel membrane keys and a display for setting-up instrument operating parameters, viewing particle number concentration and count data, interrogating instrument status, and data storage capabilities.
