• Monitor and control CO2 values in closed spaces of residential/commercial buildings and greenhouses
• CO2 range: 0 to 5000ppm, accuracy: ±50ppm or 5% of reading
• Accurate and low drift NDIR (Non-Dispersive Infrared) waveguide technology sensor
• Displays CO2 chart with adjustable time scale (week/day/hour/min/auto)
• Automatic Min/Max recall on the display

The Triplett GSM500 is a carbon dioxide monitor/controller that helps to monitor and regulate CO2 values in enclosed spaces, providing different modes for plant and human environments. Connect it to a CO2 generator for greenhouse use or control a ventilation fan for residential or commercial spaces. The included remote sensor with a 14.8-ft cable utilizes NDIR waveguide technology for precise and reliable readings.

The GSM500 offers a dynamic CO2 chart with adjustable time scales and auto Min/Max recall. Customize the preset CO2 zone and center values based on your needs. Built-in day/night auto-detection in plant mode overrides CO2 control.

An AC power cord with a controller piggyback plug, mounting screws, and tape for mounting the sensor probe are included.
