VDL Digital CO₂ Controller

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.
