Portable Digital 6-Channel Air Dust Particle Counter Temperature/Humidity Tester

• New

• Description:
  DT-9880 / DT-9881 are Particle Counter with 2.8'' color TFT LCD display & a microSD memory card for capturing images(JPEG) or video(3GP) for viewing on your PC,  providing fast, easy and accurate readings for particle counter, GAS(HCHO,CO) detectors, air temperature & relative humidity measurements. It is the first combination of these measurements in global, would be  the best instrument for environment protection and  energy save. The dewpoint temperature measurement will be very visible for wet and dry proof. It is a good hand  for industrial measurements and data analyzing, the real scene and time can be displayed on color TFT LCD. Any memory readings can be recorded in SD card. The user can  be back in office to analyze the measured air quality under the support of software.
