KS-42D Particle counter with light blocking detector
The KS-42D particle counter with light block detector enables the counting and size classification of particles from 2 μm in water and pure chemistry. It is also a high-end liquid particle counter which is equally suitable for ultrapure chemistry and ultrapure water.
Sophisticated calibration concepts document the extremely high counting efficiency of the system.
- Smallest channel 2 μm
- Suitable for the most aggressive chemistry; Also hydrofluoric acid
- Max 10 particle channels in the range between 2 and 100 μm
- Suitable for continuous online operation
- Suitable for batch operation
