The LS-H-801 Dust Particle Counter is our newly developed generation of touch screen portable dust particle counter. It features a sampling gas volume of 2.83L/min ±5% (equivalent to 0.1 CFM). The instrument is equipped with a 4.3-inch color touch screen, has an elegant appearance, and is made of full ABS material with a high-grade black spray paint finish. It uses a gas pump for continuous, stable operation with ultra-low noise and energy-saving environmental protection. It is equipped with an imported digital flow sensor for dynamic and precise control of the sampling flow. Power can be supplied via AC or the built-in high-capacity lithium-ion battery, making it convenient for mobile detection in places without access to AC power.
