AC Infinity CO2 Controller – Smart Carbon Dioxide Monitor & 2-Outlet Regulator/Fan Controller (0–10,000 PPM, Swiss Photoacoustic Sensor, Model AC-CTC7)

Precision Carbon Dioxide Enrichment & Fresh Air Exchange Control

Maximize photosynthesis, accelerate vegetative vigor, and boost flower density across your indoor cultivation facility with the AC Infinity CO2 Controller – Smart Carbon Dioxide Monitor & 2-Outlet Controller (Model AC-CTC7). Purpose-built for sealed grow rooms, hydroponic grow tents, greenhouses, and mushroom fruiting chambers, this intelligent environmental controller continuously monitors ambient carbon dioxide levels and automatically switches your CO2 dosing and ventilation equipment on or off to maintain exact Parts Per Million (PPM) targets. Supporting up to 1,100W (10A) across dual smart outlets, the AC-CTC7 eliminates guesswork and wasted CO2 gas while safeguarding your grow space against dangerous PPM spikes.

Swiss-Made Photoacoustic CO2 Sensor with 12-Foot Corded Probe

At the core of the AC Infinity CO2 Controller is a fast-responding, high-accuracy Swiss-made photoacoustic CO2 sensor mounted at the end of a generous 144-inch (12-foot) probe cord. Capable of measuring concentrations across a wide 0 to 10,000 PPM range, the probe hangs directly at canopy height to capture true plant-level readings rather than inaccurate wall averages. Built-in manual calibration (±500 PPM) and automatic baseline calibration (400 PPM ambient reference) ensure long-term sensor accuracy across multi-year production runs.

Dual Independently Programmable Smart Outlets (CO2 & Exhaust)

Equipped with two independently programmable AC outlets, the AC-CTC7 lets you simultaneously manage both enrichment and air exchange from a single hub. Configure Outlet 1 to trigger a solenoid-equipped CO2 regulator or CO2 generator whenever PPM drops below your target range, while programming Outlet 2 to activate an inline exhaust fan whenever CO2 or heat exceeds upper thresholds. In addition to dynamic CO2 and Fan trigger modes, growers can utilize customizable Cycle timers, continuous ON/OFF overrides, and Center/Zone buffering to prevent rapid device short-cycling.

Nighttime CO2 Shutoff Protection & High/Low PPM Alarms

Because plants do not photosynthesize in the dark, releasing CO2 during lights-off periods wastes gas and risks unsafe buildup. The AC-CTC7 features dedicated Night Mode 1 and Night Mode 2 scheduling to automatically pause CO2 enrichment during dark cycles while maintaining safe ventilation thresholds. Visual and audible High and Low PPM alarms immediately alert you if tank pressure runs empty or levels climb above safe occupational limits.

Real-Time Backlit LCD & Historical Data Graphing

View live PPM readings, active outlet status, countdown timers, and up to 30 days of historical CO2 data graphs directly on the crisp 2.53″ × 2.98″ LCD screen. With adjustable backlight brightness and dark-period auto-dimming options, the display prevents unwanted light leaks inside photoperiod grow tents.
