Particle Sensor KS-42AF

A highly reliable particle sensor that can measure 0.1 µm particles. Measurements can be made using only small amounts of samples due to high counting efficiency.

Semiconductor > Particle Counter Semiconductor > Liquid Particle Counter Semiconductor


Minimum particle size of 0.1 µm,sample flow rate of 10 mL/min
Particle size range (5 channels, factory default setting) ≥0.1µm,≥0.15µm,≥0.2µm,≥0.3µm,≥0.5µm
Leakage detector built-in. Outputs alarm when internal leak detected
A sapphire flow cell is used in KS-42AF
Channel size change possible within range of sensor (using KE-40B1)
