- Accurate and low drift NDIR (non-dispersive infrared) waveguide technology
- Displays CO2 chart with adjustable time scale (week/day/hour/min/auto)
- Automatic Min/Max recall on the displayed chart
- Preset CO2 zone and center values for human or plant mode
- Programmable CO2 zone value and center value to control output power on/off

Manage your indoor COâ‚‚ levels with the GSM500 Carbon Dioxide Monitor/Controller. This versatile device helps to monitor and regulate COâ‚‚ values in enclosed spaces, providing different modes for plant and human environments. Connect it to a COâ‚‚ generator for greenhouse use, or control a ventilation fan for residential/commercial spaces. The included remote sensor with a 14.8ft (4.5m) cable utilizes NDIR waveguide technology for precise and reliable readings. The unit also offers a dynamic COâ‚‚ chart with adjustable time scales and auto Min/Max recall. Customize preset COâ‚‚ zone and center values based on your requirements, with built-in day/night auto detection in plant mode for overriding COâ‚‚ control. The package includes an AC power cord, mounting screws, and tape for mounting the sensor probe. Backed by a 1-year warranty for peace of mind.
