From

0

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.
