Heavy-Duty Portable Emissions Measurement Systems
The SEMTECH® DS+ heavy-duty portable emissions measurement system (PEMS) is designed to meet worldwide regulatory standards for heavy-duty vehicles and off-road equipment. Modules are designed to work with each other with minimal connections.
Gaseous / Exhaust Flow
The SEMTECH® DS+ base system contains a sample conditioning unit and measures exhaust flow, CO, CO2, NO, and NO2. Additional modules mate directly via electrical and pneumatic connections, minimizing lines, pneumatics and cables.
The SEMTECH® CPN measures the solid particle number concentrations of engine exhaust particles and is fully compliant with both the current and developing worldwide regulations for particle number measurements. Incorporating a volatile particle removal and a proprietary condensation particle counter.
The SEMTECH® PM2 is a second generation on-board Particulate Matter (PM) measurement device that combines real-time and cumulative PM mass measurements, using both an ion mobility technique and a gravimetric method in a single module.
Measure Total Hydrocarbons (THC) in real-time with the SEMTECH® Flame Ionization Detector (FID), which works as a stand-alone device or as an add on to either the SEMTECH® LDV or the SEMTECH® DS+. A Dual FID configuration is also available that measure THC and methane.
