The digital CO₂ controller is an easy-to-use controller for measuring and maintaining CO₂ levels in your greenhouse or grow room: a large digital LCD display where you can read the ppm, day, hour, minute, alarm, etc. levels in real time. This display is divided into zones, making it much easier and quicker to locate the parameter readings. 

• Center: you can mark the CO₂ levels you want in the room
• Zone: hysteresis or dead band

It has an external probe (ppm), with a 4.5 meter cable, and a photocell to activate the controller during the day, since it is not necessary at night. It has a fuse that protects the controller. Calibrate the controller easily and quickly, just by pressing the button enabled on the probe for 3 seconds, placing it outside so that it starts at 400-450 ppm. After 15 minutes, the controller will be ready.

You can change the probes to have the controller as precise as the first day.
