At present, air quality sensor indoor the commonly used environmental air quality testing instruments include carbon dioxide concentration detectors. PM2.5 and PM5 particle detector, sulfur dioxide detector, etc. In addition, there are many general analytical instruments that are also used for air quality testing. For example, infrared spectroscopy can be used to detect the concentration of ozone in the air.
In general, it is an instrument used for indoor air quality testing. It is more inclined to the comprehensiveness of functions, and it is usually possible to detect multiple air quality parameters at the same time. And compared to equipment used outdoors. Indoor air quality testing instruments will pay more attention to some common indoor air pollutants. Such as formaldehyde, TVOC. In addition, for most families who have an indoor air detector. Fresh air installations are also the focus of procurement. Therefore, many indoor air detectors will be used in conjunction with fresh air devices. Judge the indoor air through the instrument. Then determine the operating mode of the fresh air system and remind users to open windows for ventilation.
air quality sensor indoor
But whether it is indoor or outdoor. The key to the quality of air quality testing equipment lies in the accuracy of the testing results of the equipment. And this. To a large extent, it is determined by the quality of the gas sensor in the air quality detection instrument and the design structure of the instrument. Generally speaking, a sensor corresponds to the detection of a gas. For example, most indoor multi-parameter air detectors. Inside will be equipped with formaldehyde sensor, PM2.5 sensor. TVOC sensor, temperature and humidity sensor. However, the sensors may affect each other. Therefore, only each sensor can guarantee the accuracy of the detection result. And the structural design can ensure that the air sample does not interfere with each other under the premise of contacting each sensor. In order to ensure the test results of the instrument.
Then how do consumers choose air quality testing equipment correctly? According to the editor, you should determine your purpose before buying. For commercial use or for home use, the next step is to determine whether you need such an instrument. For most families, the indoor space is moderate. The north-south ventilates, and it is not a new house. And the surrounding air environment is pretty good. So as long as the regular indoor ventilation can be ensured, the indoor air quality can be guaranteed. There is no need to spend extra money on unused equipment. And if you are sure you want to buy it. You need to know the basic parameters of the product and the relevant certificate of conformity from the manufacturer. Ensure that the operation of the instrument is based on the indoor air quality parameters and inspection methods specified in the “Indoor Air Quality Standards” and the error is within the acceptable range.
