 Features

 

1. Using a mix gas sensor to detect real time air quality.

2. Japanese semiconductor gas sensor with 5~7 years long lifetime.

3. Monitor temperature and relative humidity

4. LCD display air quality as well as temperature and humidity, fan status etc. Makes reading and operating easy and accurate.

5. user-friendly setting buttons and easy to operate.

6. Temperature and humidity compensation makes the IAQ measurement more consistent in different environments with more accuracy reading.
