The TrolMaster Beta-8 is a standalone digital CO₂ controller designed to maintain a precise CO₂ PPM setpoint in a sealed or semi-sealed grow room. It works with both CO₂ regulators and CO₂ generators, using a remote NDIR sensor positioned at canopy level to continuously measure CO₂ concentration. The controller uses fuzzy-logic output control to reduce overshoot, an adjustable deadband to fine-tune the target range, and a built-in photocell to automatically suppress CO₂ injection during dark periods.

Key Advantage: The Beta-8 provides a dedicated closed-loop CO₂ control system without requiring a full environmental controller. Its NDIR sensing, adjustable deadband, fuzzy-logic output, and automatic day/night detection are particularly useful for maintaining a stable CO₂ concentration while reducing overshoot and unnecessary CO₂ consumption.
