greenhouse CO2 monitor & controller

Part Number: ESRAD-501

CO2 Detector GreenhouseThis Day/Night CO2 Controller can be used in greenhouses, hydroponics rooms, mushroom houses, growth cabinets and other places where elevated carbon dioxide levels are used to maximize plant growth.

  • Accurate CO2 Generator Control
  • Photo Sensor Turns off CO2 at Night
  • Easy Fresh-Air Calibration

 

The Day/Night CO2 Monitor & Controller lets you set minimum and maximum carbon dioxide levels. When the minimum level is sensed, power is supplied to a CO2 generator or regulator via the built-in 110-240 VAC 5A piggyback power cord. When the maximum level is reached, the power is turned off.

In addition, the CO2 Monitor & Controller has a built-in photo sensor that overrides the CO2 control and shuts off the CO2 when it senses darkness. Photo sensor control saves dollars and energy by ensuring you’ll only be supplying CO2 during the light cycle when it is needed.

Best of all, the CO2 Monitor & Controller is easy to install and use. Simply mount the unit inside your greenhouse, (all cables and hardware included), plug it into a standard wall jack, plug in your CO2 generator or regulator and it is ready to maximize your plant growing yields.
