Temtop PM-900M Laser Particle Sensor is equipped with a laser-based particle sensor that works on the principle of light scattering method to detect, count particles and also calculates PM1.0, PM2.5, PM10 concentration in a given environment. This Temtop laser particle sensor features an imported processing chip and photosensitive element. The Signals are collected and processed by the microprocessor chip and then output in digital format. PM-900M Laser sensor is ideal to detect the concentration of different particles precisely in real-time.
