Air Particle Counter


Air Particle Counter

DT-9881

Particle Counter with unique 2.8”color TFT LCD display and built-in camera for capturing videos and photos that are stored onto internal memory or a micro SD card, for viewing on PC, providing fast, easy and accurate readings for particle counter, Air Temperature, Relative Humidity, Dew Point & Wet Bulb Temperature and , Gas Detection (DT-9881 only). The DT-9880/DT-9881 can measure up to 6 channels of particle sizes Use the included software to generate reports with videos, photos, and data points.  DT-9881 can also detect and measure the concentration of HCHO (Methanal) Gas and CO (Carbon Mono-Oxide) Gas.
