It is the first combination of these measurements in world. Would be the best instrument for environment protection and energy conservation. The dew-point temperature measurement will be very visible for wet and dry proof. It is a good handy industrial measurement and data analyser. The real scene and time can be displayed on color TFT LCD. Any memory readings can be recorded in Micro SD card. Offline analysis of the measured air quality under the support of software, can be done.
