Pro-Leaf PPM-B1 Digital CO2 Controller

Pro-Leaf PPM-B1 CO2 Controller

The Pro-Leaf PPM-B1 is a digital CO2 controller designed to deliver precise, automatic regulation of carbon dioxide levels in indoor grow environments. With intuitive operation and advanced control modes, this device helps maintain optimal CO2 concentrations to maximize photosynthesis, accelerate plant growth, and enhance yields.

Equipped with a remote sensor featuring a built-in photocell and a 4.5-meter cable, the controller continuously monitors ambient CO2 levels in real time, ensuring immediate system response. Its design allows it to operate only during light hours, avoiding CO2 waste during dark periods.

Key Features:

• Automatic CO2 control to maintain ideal levels between 400 and 2000 PPM

• Three operation modes:

  • PPM UP (for CO2 generators)

  • FUZZY LOGIC (high precision for tanks with regulator)

  • PPM DOWN (for reduction via ventilation)

• Adjustable hysteresis (deadband) for customized on/off thresholds

• Real-time CO2 readings on display

• Min/max value logging for historical monitoring

• Manual calibration available for maximum accuracy (reference point: 400 PPM)

• Plug & Play setup – fast installation with no complex configuration

• Built-in photocell – automatically detects day/night cycles

• LED indicators for system status and errors
