Product description:
[High performance Gas Sensor]
While using the dual-channel NDIR?Air Sensor?by this?indoor air quality tester, it can monitor the temperature, CO2, and Relative Humidity on 3.5 inch TFT display screen.
NDIR?Gas?Sensor is a high-precision,fast measurement response sensor with long-term stability and long battery life, which can make our carbon dioxide detector operate efficiently.
?
NDIR dual-channel sensor VS chemical sensor😕 
1.? 1 second VS. 3 minutes, NDIR dual-channel sensor can achieve fast and accurate response
2? ?Stable accuracy VS continuous decline, NDIR dual-channel sensor relies on analyzing the wavelength of different air components to measure, test The sensor is not damaged.
The chemical sensor is based on the chemical reaction of different air components for measurement. Each measurement will damage the sensor, so the measurement accuracy continues to decline
3? ?15years VS 1-3years, the service life of chemical sensors is generally only 1-3 years,
while NDIR The dual-channel sensor has a service life of 15 years and is generally used in laboratory analytical instruments.
[Accuracy and Multi-Scene use]
This Air Quality Meter is able to offer the accurate information about air quality in indoor places such as family, offices and greenhouse.
By delivering different text colors about CO2, this kind of home air quality monitor can display the hazard level by green(Mild), yellow(moderate) and red(Severe).
[Fully automatic function]
According to the temperature unit in environment, this air monitor can automatically adjust the brightness of the backlight.
It?can continuously measure carbon dioxide ,temperature and relative humidity, which are all automatic calibrated.
[Wide measuring range]
By using our indoor CO2 detector, you can easily test carbon dioxide content in air, 45-120 Fahrenheit and Relative humidity between 1-99%.
At the same time, trend image can be seen through this air quality monitor.
[Clear Display, Safety and Easy to Operate] ?
With the easy-operated 3.5 inch large-size color TFT capacitive touch screen,
Our best air quality monitor can display the seven days data of CO2, temperature and relative humidity on the home screen.
Carbon dioxide alarm reminder can point out the high level of CO2.
Moreover, our best indoor air quality monitor?with password protection can make you set a screen lock to unlock the device.
Every time you operate, you will be asked to enter a PIN code to unlock the device.
The harm of carbon dioxide:
- Natural environment
The greenhouse effect refers to the fact that solar waves enter the ground through the atmosphere, and the long-wave radiation emitted by the ground is absorbed by carbon dioxide and other substances in the atmosphere, leading to climate warming.
The continuous intensification of the greenhouse effect has led to global warming and has produced a series of unpredictable global climate problems.
The surface temperature continues to rise, glaciers melt and sea levels rise.
The high temperature has also aggravated the spread of the dengue fever virus, causing numerous forest fires.
- Human health
When the concentration of carbon dioxide in the air is higher than 2%, it will damage the respiratory organs of the human body and cause symptoms of poisoning.
Mild discomfort such as headache and muscle weakness may occur, and severe discomfort may cause breathing difficulties, coma, and even death.
