From portable to Wi-Fi monitoring
Our range include CO2 monitors, particulate matter sensors, and multi-parameter devices that can measure various air quality indicators such as PM2.5, CO2, formaldehyde, total volatile organic compounds (TVOCs), temperature, and relative humidity. There are portable CO2 monitors with data logging capabilities, and Wi-Fi connected air quality monitors like the Davis AirLink that can measure PM1, PM2.5, and PM10.
The HOBO MX1102A CO2 logger measures carbon dioxide, temperature, and relative humidity with Bluetooth connectivity for easy data offload to mobile devices. For more comprehensive IAQ monitoring, the HOBO MX1104 and MX1105 loggers can connect to a variety of external sensors to measure CO2, VOCs, particulate matter, and other parameters.
