Product Details
28.3L Particle Counter KGD - OPC - 201
Product Introduction
The online particle counter KGD - OPC - 201 adopts the principle of
optical scattering. It can accurately detect and calculate the
number of suspended particulate matter with different particle
sizes in the air per unit volume. It has a built - in dust source
intelligent recognition module unique to KACISE Optoelectronic, and
a high - flow gas sampling rate of 28.3L/min. It can simultaneously
output the particle numbers of five channels: 0.3μm, 0.5μm, 1.0μm,
5.0μm, and 10μm (the default unit is pcs/28.3L, and it can be
switched to pcs/m³). The indication error meets the requirements of
the JJF - 1190 standard.
Product Features
- Built - in ultrasonic gas flow sensor for constant - current
sampling.
- Long - life, high - power linear laser for efficient particle
recognition.
- Low - noise turbine fan for sampling, with good stability in
continuous monitoring.
- Open communication protocol, facilitating customer integration.
