SuperPro D1-PPM Digital CO2 Controller – For Grow Rooms

Dose CO2 Only When Your Plants Can Use It

The SuperPro D1-PPM Digital CO2 Controller manages a CO2 regulator or CO2 generator from a single power outlet on the front of the unit. It reads the room through a precise NDIR CO2 sensor housed in a remote sensor enclosure that hangs up to 5 metres from the controller, so the reading comes from canopy level rather than the wall. You choose the target from 350 to 2000 ppm on the digital display, set a deadband, and the controller switches your CO2 source on below the setpoint and off once the level reaches setpoint plus deadband.

Key Benefits

• NDIR sensing – the accurate infrared method used in professional CO2 equipment.
• Setpoint 350–2000 ppm – from gentle top-up to full enrichment in a sealed grow room.
• Built-in photocell in the sensor pod, so CO2 is released only during the light period.
• Adjustable deadband – stops a regulator or burner cycling on and off every few seconds.
• CO2 reduction mode – can run an extractor fan to pull CO2 levels down instead.
• Plug-in design with a UK socket for the CO2 device.

Wasting CO2 Overnight?

Plants only take up carbon dioxide while the lights are on. A timer or a simple on/off regulator keeps releasing gas through the dark period and between readings, emptying cylinders for no gain in growth. Tying dosing to a real ppm reading and to the light level means every litre released goes into photosynthesis during the hours it matters.

How to Use

• Hang the sensor enclosure at canopy height, away from the CO2 outlet and out of direct fan airflow.
• Plug your CO2 regulator solenoid or CO2 generator into the socket on the front of the controller.
• Enter your target ppm and deadband on the digital display.
• Leave the photocell uncovered so the unit doses only in the light period; switch to reduce mode if you want it to run a fan instead.
