Product Details
Laser Particle Counting Sensor KGD - PM - 203
Product Introduction
The KGD - PM - 203 laser particle counting sensor is based on the
principle of optical scattering. It can accurately detect and
calculate the number of suspended particles with different particle
sizes in the air per unit volume. It can simultaneously output the
particle numbers (pcs/L) of six channels: 0.3μm, 0.5μm, 1.0μm,
2.5μm, 5.0μm, and 10μm, and its counting efficiency meets the
calibration standard specifications of the JJF 1190 - 2008 for dust
particle counters.
Product Features
- Outputs the numbers of particles with sizes of 0.3μm, 0.5μm, 1.0μm,
2.5μm, 5.0μm, and 10μm.
- Constant current sampling, with high stability in long-term
operation.
- Constant-power linear laser for accurate identification.
- Meets the calibration standard specifications of the JJF 1190 -
2008 for dust particle counters.
