Particle Sensor KS-42BF

A wide measurement range of particle from 0.2 µm to 2.0 µm. Measurements can be made using only small amounts of samples due to high counting efficiency



Measuring Instruments > Particle Counting Systems > Liquid Particle Counter
Semiconductor > Particle Counter Semiconductor > Liquid Particle Counter Semiconductor


Minimum particle size of 0.2 µm, sample flow rate of 10 mL/min
Particle size range (5 channels, factory default setting)
≥ 0.2 µm, ≥ 0.3µm, ≥ 0.5µm, ≥ 1.0µm, ≥ 2.0µm
Leakage detector built-in Outputs alarm when internal leak detected
A sapphire flow cell is used in KS-42BF
Channel size change possible within range of sensor(using KE-40B1)
