TrolMaster Digital CO₂ PPM Controller (BETA-8)

Accurate, Efficient CO₂ Control with Advanced NDIR Technology

The TrolMaster BETA-8 Digital CO₂ PPM Controller delivers precise and reliable CO₂ management in an easy-to-use, affordable package—making it a top choice for growers who demand consistent CO₂ enrichment to maximize plant growth and yield. Equipped with a high-accuracy NDIR (Nondispersive Infrared) CO₂ sensor and a 16 ft remote sensor cable, the BETA-8 allows for ideal placement at canopy level to ensure accurate monitoring inside any grow room, greenhouse, or grow tent.

To improve efficiency, the BETA-8 features a built-in photocell that automatically activates CO₂ delivery only during daylight hours, preventing waste and ensuring your plants receive enriched CO₂ precisely when they need it for photosynthesis. Adjustable deadband settings, min-max recall, and intelligent fuzzy-logic control further enhance accuracy—especially when using compressed CO₂ systems—by preventing overshooting and delivering smooth, stable dosing.

Easy to calibrate and built for long-term reliability, the BETA-8 provides professional-grade CO₂ control that supports stronger growth, faster development, and higher yields.
