Optimize Your Growing Environment
Professional CO2 monitoring that transforms plant productivity
Precision CO2 Monitoring
Dual NDIR sensors deliver laboratory-grade accuracy from 0-5000PPM, ensuring your plants receive optimal carbon dioxide levels for maximum photosynthesis and growth rates.
Intelligent Day/Night Control
Built-in photocell automatically adjusts monitoring based on natural light cycles, optimizing CO2 delivery when plants photosynthesize most actively during daylight hours.
Real-Time Growing Insights
Live digital display shows instant CO2 readings, allowing you to make immediate adjustments and track environmental conditions that directly impact plant health and yield.
Flexible Sensor Placement
4.6-meter remote cable positions the sensor precisely at canopy level where CO2 concentration matters most, while keeping the controller accessible for monitoring and adjustments.
Low-Drift Reliability
Advanced NDIR technology maintains calibration accuracy over time, reducing maintenance needs and ensuring consistent performance season after season in your greenhouse.
Enhanced Plant Performance
Proper CO2 management supports vigorous growth, improved flowering, and higher yields by maintaining the optimal atmospheric conditions plants need to thrive indoors.
From Guessing to Growing
Transform uncertain plant care into precision greenhouse management
BEFORE
Inconsistent Plant Growth
- Guessing at CO2 levels with no real measurement data
- Plants showing slow growth despite proper watering and nutrients
- Wasting money on CO2 generation without knowing effectiveness
AFTER
Optimized Growing Environment
- Precise CO2 monitoring with laboratory-grade NDIR sensor accuracy
- Vigorous plant growth from optimal 800-1200 PPM CO2 levels
- Efficient CO2 usage with day/night automation saving costs
Growers report 25-40% yield increases when maintaining optimal CO2 levels

Everything You Need to Know
Get confident about optimizing your greenhouse CO2 levels
Most greenhouse crops thrive with CO2 levels between 800-1200 PPM during daylight hours. This controller monitors 0-5000 PPM, covering all growing scenarios from ambient (400 PPM) to enhanced CO2 supplementation.
NDIR (Non-Dispersive Infrared) technology provides laboratory-grade accuracy with minimal drift over time. The dual-channel design offers redundancy and enhanced reliability compared to single-sensor systems.
Yes, the controller is designed to integrate with CO2 generation systems and ventilation equipment. Wiring diagrams are included for common greenhouse automation setups.
Plants only use CO2 during photosynthesis (daylight hours). The photocell prevents unnecessary CO2 generation at night, saving costs and preventing CO2 buildup that could harm plants.
Your order includes the main controller unit, dual NDIR sensor with 4.6-meter cable, mounting hardware, and installation guide. Free Shipping on Most Orders Within the Continental U.S. (Excludes AK/HI) within the continental U.S. with delivery in 6-11 business days.
