MODEL 5412


The advanced condensation particle counter

The GRIMM 5412 is the advanced compact and rugged instrument of the Grimm CPC line with integrated sample pump and an aerosol sample flow rate of 0.6 L/min. The new detection head enables single particle counting up to 100 000 particles /cm³ with improved detection efficiency (D50 = 4nm) and response time (t10-t90 < 3 s). The photometric mode allows for the detection of high concentrations up to 107 particles/cm³. As all GRIMM CPC models, the 5412 features the well-established condensate removal and anti-spill saturator design with an integrated saturator shutter, enabling the transport of the CPC without removing or drying the saturator.
