TrolMaster BETA-8 Digital CO₂ PPM Controller – Precision CO₂ Management for Optimal Plant Growth

The TrolMaster BETA-8 Digital CO₂ PPM Controller delivers highly accurate CO₂ monitoring and control using an advanced NDIR (Nondispersive Infrared) sensor—packaged in a simple, affordable, and user-friendly design. Engineered for growers who need reliable CO₂ enrichment, the BETA-8 ensures your plants always receive the ideal CO₂ levels for vigorous photosynthesis and maximum yield.

Equipped with a remote CO₂ sensor (with 16 ft cable) and a built-in photocell, the BETA-8 automatically activates supplemental CO₂ equipment only during daylight hours, preventing waste and ensuring efficient operation. Adjustable deadband settings, min/max recall, and smart “fuzzy-logic” control allow for precise management, especially when using compressed CO₂ systems.

Accurate, dependable, and easy to recalibrate, the BETA-8 provides professional-grade CO₂ control that growers can rely on for many years.
