TrolMaster Digital - Digital CO2 PPM Controller (BETA-8) is a digital co2 ppm controller for maintaining target CO2 ppm levels during daylight hours in controlled growing environments. It’s built around a precision co2 ndir sensor to keep monitoring steady, readable, and responsive when CO2 control is part of your daily environment management. At the core is a remote co2 sensor paired with a built-in photocell sensor, creating daylight-only co2 control that automatically shuts off CO2 output at night. That focus on day operation helps keep CO2 management aligned with the periods when supplemental CO2 is intended to run, while keeping nighttime behavior simple and predictable. For tighter control, the BETA-8 includes adjustable deadband to help reduce unnecessary cycling around your target range. A fuzzy-logic control mode is designed to more accurately manage compressed CO2 systems by smoothing control behavior as readings approach the setpoint. It’s a practical approach when you want steadier ppm control rather than wide swings. A clear digital display makes quick checks easy, and min-max recall helps you review how high and how low CO2 levels have reached over time. The CO2 sensor is designed to be re-calibrated when needed, supporting long-term accuracy and dependable monitoring season after season. This controller is a strong fit for growers who want straightforward, single-purpose CO2 ppm level control with modern sensor-based feedback. If you value reliable readings, day-night automation, and refined control behavior, the BETA-8 keeps CO2 management clean, consistent, and easy to understand. Product benefits: Indoor.
