Model 300 Laser dust particle detector


The model 300 air quality detector used to detect the air quality for the 4 particle channels : 0.5um, 1.0um, 2.5um and 10um, with two detection mode: Quality inspection(unit of the ug/m3) and Quantity inspection(unit of the PC/L). Also with the Temperature and Humidity measurement, optional function of the gas concentration detection, it can add 3 sensors for gas detection. It’s with the data logger function to record the historic inspection data.

  • Semiconductor technology of ultra low power 32 bit microprocessor, 24 bit ADC acquisition chip, so with the high accuracy.
  • 3.5 inch IPS industrial grade color screen, displaying each parameter.
  • Channel sizes:0.5um, 1.0um, 2.5um, 10um.
  • Support the Temperature/ Humidity sensor.
  • Different mode adjustable: quantity detecting mode and quality detecting mode.
  • Data logger function, the capacity is 100000 group data.
  • Optional function of micro printer to print the measurement data.
  • With the function of overvoltage protection, overcharge protection, short circuit protection, anti-electrostatic interference, anti-magnetic interference.
  • Chinese/English operation menu.
