This 7530 wallmount CO2 Controller comes with an external CO2 sensing probe that will help in measuring CO2 level in closed spaces. You can use it for CO2 monitor in indoor air quality and green house CO2 measurement. Can also use and operate in other work space like office, hospital, school, station, residential, commercial building or home usage. You can also use it in controlling other connected instrument such as CO2 generator or ventilation fan easily by two modes (the plant OR human mode) to override the controlling in low or high CO2 concentration.

7530 offers you a simple and affordable way to control and monitor CO2 levels in a Greenhouse, residential, hydroponics, mushroom farm, commercial building and so on.
