Streulichtpartikelzähler KS-20F

KS-20F Particle counter with light blocking detector

The KS-20F scattered-light particle counter can count and size-classify particles from 0.02 µm. This highly developed device is specially designed for measurements in aggressive chemicals such as hydrofluoric acid and offers excellent performance thanks to its advanced calibration concept and optical system technology. Sophisticated calibration concepts round off the system's high performance.

  • Detects particles to 0.02 µm
  • Compatible with Hydrofluoric acid
  • With abundant options, it can be used for both in-line and off-line measurement
