In order to achieve better purification effect and improve air quality, more and more enterprises and institutions, especially restaurants, hotels, clubs and other service-oriented organizations, choose to install indoor air quality detector while paying attention to indoor environment quality. Because compared with the previous detection of professional testing institutions, the indoor air quality detector can achieve long-term online monitoring, but also real-time display of data for indoor environment purification has played a good role in evaluation and warning. So how much is the price of indoor air quality detector?
How much is the indoor air quality detector?
LUFTMY PM2.5 detector is a special instrument used to measure the value of PM2.5 in the air. It is suitable for the measurement of public place environment, atmospheric environment and indoor air, and can also be used for the evaluation and analysis of purification efficiency of air purifier.
Indoor air quality detector is usually used to detect indoor air quality, and the types of detection instruments are different according to the different requirements of installation site and detection items. Our common test items, such as: temperature, humidity, PM2.5, PM10, formaldehyde, TVOC, carbon dioxide, etc. In some special places, noise, light and oxygen are also used. Because of the different test items, the different sensor elements in the equipment are defined, and the natural price of the test instrument with more sensors is higher. Therefore, when purchasing indoor environmental monitoring instruments, we must pay attention to detection items and monitoring accuracy, which is the key to determine the price of indoor air quality detector.

In addition, the detection requirements are also reflected in the form of data. Some users need long-term monitoring and analysis equipment when they purchase, but they often unconsciously see the handheld air detector. In fact, there are two different forms of indoor air quality detector. One is a simple hand-held detector, which is similar to the spring scale. When it is opened, the detection value can be seen, but the value can not be derived, only simple estimation can be made.The market supervision bureau has calibrated and tested the hand-held detectors on the market, and the result is that more than 80% of the hand-held detectors can not meet the requirements of accurate measurement.
The other is the indoor environment online monitoring system, which is more complex than the hand-held detector. It is established in the networking mode, and transmits the detection data to various screens and operating systems such as computers and mobile phones. Through the long-term fixed-point detection of a certain area, it can accurately count the indoor environment in the current area, and can also use tables, charts and other forms to transfer the historical data The result can be used to monitor the source of indoor environmental pollution and improve the environment.The essence of hand-held detector and indoor environment online monitoring system is to detect indoor environment, but the actual application scenarios and processes are far from each other, and the purchase price is directly proportional to practical functions.
High precision laser PM2.5 sensor LD11 is a high precision particle concentration sensor based on laser Mie scattering theory. It can continuously collect and calculate the number of suspended particles with different particle sizes in the air per unit volume, i.e. particle concentration distribution, and then convert it into mass concentration, and output it in the form of general digital interface.Laser digital PM2.5 sensor LD11 has the characteristics of small volume, high precision, strong anti-interference ability, low power consumption, long service life, short response time of zero error alarm rate, etc. This high-precision laser PM2.5 sensor can be embedded in various instruments related to the concentration of suspended particles in the air, such as air detector or environmental improvement equipment, to provide timely and accurate concentration data.
