AM7p HCHO Detector Air Quality Detect Machine Home Circumstance Tester ( Item#: E9752 )

These devices are mostly used in home air circumstance testing, which based on modular design theory. Provides up to 7 daily air quality data references. The built-in rangy temperature reading calibration technology allows the user to manually adjust the reading values within the range of -10 to 35 Celsius degrees. The Auto Sense technology built-in the V-4 formaldehyde amp module suppresses long-term using drift of the formaldehyde sensor and provides 4 seconds faster response data. Fully open design makes the internal airflow exchange smooth, and temperature, humidity detection sensitive, which is more accurate by comparing  other competing products using built-in probe and compensation method to calculate temperature. You can have a try.

Features:
Miniaturized 7 in 1 home air quality integrated detecting solution, help detect PM2.5, PM10, HCHO, TVOC, CO2, TEMPERATURE, Relative Humidity.
Modular unit design, hot swappable sensor components, easier to maintain.
Provides up to 7 daily air quality data references.
The formaldehyde detection sensor uses a brand new V-4 amp module to provide <150uV low-temperature drift performance.
Formaldehyde detect sensor provides least significant bit resolution as low as 0.004mg/m3.
The new rangy temperature calibration technology allows device adjusting could be done under outdoor environments even at -10 °C.
Rapid data output capability, all reading data can be recorded every 4 seconds in extended TF card.
Fully open design makes the internal airflow exchange smooth, and temperature, humidity detection sensitive, which is more accurate by comparing  other competing products using built-in probe and compensation method to calculate temperature.
The whole device is equipped with 18650 lithium battery, easy to replace and purchase, standard version can provide 6 hours of battery life.
AIR MASTER devices can guarantee stable long-term test of 7*24 hours by connecting with micro-USB port.
Non consumable materials, 3 to 5 years of average sensor life.
