This 7530 wall-mount CO2 Controller comes with an external CO2 sensing probe that will help in measuring CO2 levels in closed spaces. You can use it for CO2 monitoring in indoor air quality and greenhouse CO2 measurements. It can also use and operate in other workspaces like offices, hospitals, schools, stations, residential, commercial buildings, or home usage. You can also use it in controlling another connected instrument such as a 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.
