GRIMM - Model 5430 and 5431 -High Accuracy Stationary Particle Counter
The GRIMM 5430 is a high accuracy stationary particle counter for automotive emission measurements with improved response time (t10-t90 < 3 s) and an aerosol flow rate of 0.6 L/min. The instrument complies to the GPRE particle measurement program (PMP) for Euro 5 and 6 regulation 83. The new detection head enables single particle counting up to 50 000 particles /cm³ with a coincidence correction
