Particle Counter with TFT color LCD display

9850M/9851M are Particle Counter with 2.8” color TFT LCD display & a microSD memory card , providing fast, easy and accurate readings for particle counter, HCHO 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.
