Pro-Leaf PPM-B1 CO2 Controller – Automatic CO2 Management

The Pro-Leaf PPM-B1 CO2 Controller monitors carbon dioxide levels and switches compatible equipment to help maintain your chosen set point in an indoor growing space. A remote infrared sensor and real-time digital display make it easy to keep track of conditions without relying on manual switching.

Control that suits your setup

• Choose PPM UP for a compatible CO2 generator, FUZZY LOGIC for a cylinder-and-regulator setup, or PPM DOWN for a compatible extraction fan.
• Adjust the CO2 set point and deadband, the gap between switching thresholds, to suit your equipment.
• A built-in photocell limits CO2 supplementation to light hours.
• Recall recorded minimum and maximum CO2 readings to review changing conditions.
• Remote sensor with a 4.5m lead offers flexibility when positioning the sensor.
• 12-month warranty.

Installation and use

Check equipment compatibility and electrical load before connecting devices. Use FUZZY LOGIC only with a cylinder-and-regulator setup, not a CO2 generator. Keep the controller and sensor away from direct water contact and follow the manual for mounting, calibration and safe operation. The sensor is factory calibrated; the manual explains how to check and recalibrate it when needed.
