The C.A.P. CO₂-2e combines the three most important controls for your growing area—all in one unit. It separately controls temperature, humidity and CO₂ levels. Its built-in photocell ensures that the CO₂ valve or generator is only active during the day when the HID lights are on.

It has two timers that are used to add just the right amount of CO₂ without the wasteful overshoot that other controllers have. One timer of the CO₂-2e controller manages the length of time the CO₂ is released, and the other controls how often the CO₂ is released. The result is a very efficient method of controlling CO₂.

The CO₂-2e features independent temperature and humidity controls which will disable CO₂ injection if the temperature or humidity levels that you specify are exceeded, activating an exhaust outlet which can control ventilation equipment (air conditioner, exhaust fan, etc.). The external remote temperature probe is very reliable, and it can be placed up to 30" from the unit.

For ease of manual monitoring, there are three indicator lights to verify Exhaust, CO₂ on and PPM level.

If you desire CO₂ control with parts per million accuracy, pick up a PPM-1c CO₂ Monitor and connect it to the CO₂-2e using the port on the lower left of the CO₂-2e.
