Product Details
Laser Particle Counting Sensor KGD - PM - 204
Product Introduction
The KGD - PM - 204 laser particle counting sensor is based on the
principle of laser scattering. It adopts an industrial-grade linear
laser with a long lifespan and high temperature resistance, as well
as an automotive-grade large-flow turbine fan, ensuring that the
sensor can stably, reliably and accurately output the numbers of
particles (pcs/L) with sizes of 0.3μm, 0.5μm, 1.0μm, 2.5μm, 5.0μm
and 10μm. The sensor uses RS485 communication, which supports
long-distance transmission.
Product Features
- Can output the numbers of particles with sizes of 0.3μm, 0.5μm,
1.0μm, 2.5μm, 5.0μm and 10μm.
- Meets the calibration standard specifications of the JJF 1190 -
2008 for dust particle counters.
- Concave surface light-gathering design, with high signal collection
efficiency.
- RS485 communication mode, supporting long-distance communication.
- Design of voltage-stabilizing circuit and EMC compatibility.
- Industrial-grade laser with high reliability.
- Design of wide voltage power supply.
- Constant current sampling, with high stability.
