The CO2 controller (CO2 concentration monitor, CO2 gas detector) is a specialized device designed to monitor and regulate CO2 levels in greenhouses, offices, farms, mushroom cultivation facilities, and other environments where precise air quality management is essential.

Maintaining optimal CO2 concentration helps plants perform photosynthesis more efficiently, increases crop yield, shortens growth cycles, and improves both agricultural product quality and overall air quality in living, working, and production environments.

Compact, Accurate, and Versatile

The CO2 concentration controller is compact in design yet powerful in performance. It continuously measures and controls CO2 levels in enclosed spaces such as offices, meeting rooms, classrooms, homes, and greenhouses-anywhere air quality must remain stable to protect health and enhance ventilation efficiency. With fast response and high-accuracy readings, the CO₂ monitor enables users to keep CO2 within safe and optimal ranges at all times.

Automatic Alarm & Ventilation Control

The device is equipped with a relay output for alarms and control signals, enabling automatic activation of ventilation fans, air conditioning systems, exhaust units, or fresh-air valves.

When CO2 exceeds the set threshold, the relay is triggered to activate connected equipment and quickly reduce CO2 to safe levels.

Adjustable relay sensitivity minimizes unnecessary switching when the CO₂ level fluctuates near the setpoint, ensuring stable operation and extended equipment lifespan.

High-Precision CO2 Sensor

Measuring Range: 0–5,000 ppm or 0–10,000 ppm (two options)
Resolution: ±10 ppm
Accuracy: ±50 ppm ±2% of reading (whichever is greater)
These specifications allow the device to detect even small CO₂ changes in the environment, making it highly suitable for applications with strict air quality requirements.
Durable and User-Friendly Design
Panel-mounted for easy integration into central control systems
Clear digital display with easy-to-use control buttons
Removable filter for periodic cleaning, ensuring long-term accuracy and extended sensor life
