The digital CO2 controller is an easy-to-use controller to measure and maintain CO2 levels in a greenhouse or growing room: large digital LCD screen where levels can be read in real time ppm, day, hours, minutes, alarms, etc. This screen is divided into zones which make it much easier and faster to locate the parameter reading.
 Center: you can mark the CO2 levels you want in the room  
  Zone: hysteresis or dead zone  
  It has an external probe (ppm) with a 4.5 meter cable and a light sensor, so it can work at night ( it is not necessary). It has a fuse protecting the controller. 
You can change probes to make the controller as accurate as day one.
