Product Introduction

XHPM2100typeThe automatic monitoring instrument for ambient air particulate matter uses the principle of light scattering to automatically measure the mass concentration of particulate matter in the air (e.gTSP、PM₁₀、PM_2.5、PM₁）This is a simple method for determining concentration, and the unit of particle concentration ismg/m³perhapsµg/m³It uses a laser light source emitted by a laser diode, and the focused beam followsxThe direction passes through a three-dimensional detection cavity. At the intersection of the three-dimensional detection cavity, the tested sample iszDirectional import and interaction with the laser beam to scatter some of the light. The unscattered light is absorbed when projected onto the blackbody in its original direction,The scattered light in the y-direction is detected by a sensitive detector, and the measured scattered light intensity is used to calculate the content of particulate matter in the ambient air.
