Overview

A device integrates the measurement functions of three detectors: particulate matter, gas, and ultraviolet ionization (PID), reducing the need for equipment to be carried to the work site. It is designed with a compact and user-friendly 90 degree light scattering laser photometer, and a patented particle size cutting device for real-time measurement of particulate matter; Built in sampling pump with measurement trend curve display function for weight method sampling without external installation of cyclone separator, easy to read large screen
