CEM DT-9881M Air Particle Counter + Gas Detector provides fast,easy and accurate readings for particle count, It can measure Suspended Particle Concentration, GAS Formaldehyde (HCHO) & Carbon Monoxide (CO) detectection, air temperature & relative humidity &,most surface temperature measurements.
The CEM DT-9881M Air Particle Counter has many functions. With it is possible to determine the number of particles in the size of 0.3, 2.5 and 10 µm. In addition to measuring the particles, the fine dust it can also measure the PM 2.5 and PM 10 mass concentration. The mass concentration of the fine dust determines the weight of the particles in one cubic metre.
In addition the CEM DT-9881M can also determine the formaldehyde content in ppm. During this HCHO measurement, the temperature, the ambient humidity and the dew point are determined and displayed by it. As a further important feature it can all store data and it is therefore possible to evaluate all measured values after a measurement.
It is the ideal instrument for environmental safety and energy saving surveys.
