LEICI AT-21 Formaldehyde Detector Simultaneously Measuring temperature, Humidity, formaldehyde
LEICI AT-21 Formaldehyde Detector built-in temperature and Humidity Sensors, AT-21 formaldehyde content Detector (formaldehyde gas Tester) can monitor formaldehyde concentration, Humidity, temperature three values, small size.
LeiCiIntroduction
The formaldehyde Detector is a special instrument for detecting the concentration of formaldehyde in the environment. It can measure the temperature and humidity in the environment at the same time.Leci AT-21 formaldehyde Detector is a formaldehyde detection instrument that uses imported high-performance electrochemical sensors and built-in temperature and humidity sensors. It can monitor the formaldehyde concentration, temperature and humidity in the air in real time, and understand the health status of the environment. . AT-21 formaldehyde Detector is suitable for testing in offices, residential places, cars, furniture and other environments.
Power on/off method
1. Start-up method: Press and hold the switch key of the AT-21 formaldehyde Detector until the Detector is turned on. It will first display all 0s. After about 15 seconds, the environmental data monitored by the sensor will be displayed.
2. Shutdown method: Press and hold the switch key of the AT-21 formaldehyde Detector until the screen display of the formaldehyde Detector disappears and the monitor shuts down.
Display content
The real-time formaldehyde concentration and temperature and humidity values ââcan be easily read in the formaldehyde concentration, temperature, and humidity display areas of the AT-21 formaldehyde Detector display screen . The outer display area of ââthe display screen is a power display, which can display the battery power status in real time.
Influencing factors
The ON/OFF key of the AT-21 formaldehyde Detector is affected by small organic molecules such as alcohols, aldehydes, ketones, and phenols, such as methanol, ethanol, acetone, phenol, etc. Therefore, the influence of these factors should be confirmed or avoided during the measurement process.
