1.Introduction
Thank you for purchasing this 4 in 1 Particle Counter instrument.This instrument is Particle Counter
with 2.8" color TFT LCD display & a microSD memory card for capturing imags(JPEG) or video
(3GP) for viewing on your PC. Proving fast,easy and accurate readings for particle counter, GAS
(HCHO,CO) detectors(only DT-9881),air temperature & relative humidity,most surface temperature
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 visiable for wet and dry proof.It is a good hand 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 offce to analyze the measured air quality under
the support of software.
