The MCO Home air quality monitor can detect CO2 levels in the air in real-time and trigger alarms. It features integrated sensors for volatile organic compounds (VOC), temperature, and humidity. The air quality monitor can directly control other devices, such as fans, through its outputs. The MCOEMH9-CO2 is known for its high reliability and practicality, and it can also be connected to other devices via Z-Wave technology. Please note that the MH9-CO2-230V has different dimensions than the MH9-CO2-12V. The back panel of the MH9-CO2-230V does not fit into a standard flush-mounted box. The dimensions of the back panel are 58 x 48 x 27 mm. It reliably and accurately monitors CO2 concentration in the air. Modern glass touch surface. Power supply: 230 V AC.
