CF-9A Portable Air Quality Monitor For AQI, PM2.5, PM10, CO2, Temp and Humidity,With Buzzer Alarm
Monitoring Carbon Dioxide by 9A Indoor Air Quality Monitor
This indoor air detector, equipped with the latest Non-dispersive Infrared (NDIR), can respond quickly and monitor the carbon dioxide concentration in indoor air. In addition to the NDIR chip, this indoor air detector also has a PM2.5PM10 chip. It can detect particles in the air with a diameter of 2.5μm and 10μm. In addition, this indoor air detector can also calculate the Air quality index （AQI）value based on the relevant data of indoor air quality.The AQI range is 0-500, when the AQI value over 100, we need to pay attention to the indoor air quality, open the windows for ventilation or turn on the air purifier.
What We Measure: PM 10 & Humidity
Using a nationwide network of monitoring sites, EPA has developed ambient air quality trends for particle pollution, also called Particulate Matter (PM). PM10 describes inhalable particles, with diameters that are generally 10 micrometers and smaller. Under the Clean Air Act, EPA sets and reviews national air quality standards for PM. Air quality monitors measure concentrations of PM throughout the country. EPA, state, tribal and local agencies use that data to ensure that PM in the air is at levels that protect public health and the environment. ——EPA（the United States Environmental Protection Agency）
The warmer summer months can naturally lead to more humid conditions inside our homes. We need to pay attention to mold. To achieve maximum productivity, it is important to keep an eye on the temperature and humidity inside your home. The EPA has several recommendations for reducing humidity, including venting appliances and investing in a dehumidifier.
