CO2 Monitor Controllers


CARBON DIOXIDE MONITOR AND CONTROL SYSTEMS


Research laboratories and universities have proven that increased levels of carbon dioxide will greatly improve plant growth. Plant metabolism is regulated primarily by the availability of the essential requirements - light, nutrients, water, humidity, temperature, oxygen and carbon dioxide. If any of these basic necessities are deficient or limited, then the growth rate of your indoor plants will be limited.

CO2 combines with water, nutrients and light energy through photosynthesis to produce sugars (food). These sugars provide energy to manufacture plant tissues for new growth. When CO2 levels are inadequate or inconsistent, plant growth diminishes, health and vitality decline, and crop yield is reduced.

Green Air Products offers systems that monitor and control CO2 levels. When used in conjunction with our CO2 generators or bottled CO2 and the right atmospheric control equipment, indoor and greenhouse growers will see a dramatic improvement in growth, quality and yield.

    CO2 SET POINT CONTROLLER
    The SPC-2 is designed to easily monitor and control CO2 enrichment. Just set it and forget it. This appliance is recommended for indoor use only.

    HOW THE SPC-2 WORKS

    The SPC-2 samples the air and determines the concentration of CO2 in PPM. Then when indicated by your set point values (desired PPM CO2 and elevation), the unit will activate CO2 enrichment equipment plugged into the piggy back cord. The SPC-2 has a fixed hysteresis (differential) of 20 PPM.

    EXAMPLE With a CO2 set point of 1000 PPM, the unit will activate (turn "ON") whenever concentrations fall below 1000 PPM and continued to control and allow your CO2 equipment to enrich your environment until it detects about 1020 PPM. The SPC-1 is a reactive CO2 controller and the PPM concentration of CO2 will float above 1020 PPM after defeating enrichment equipment (overshoot). NOTE: Depending on individual enclosure characteristics and air circulation as well as location placement of the monitor this factor will vary. The average swing for enrichment response is 50 to 100 ppm which is actually a more desirable enrichment refresh frequency.

    FEATURES
    • Set and Forget; Easy to install and operate
    • Factory calibrated and inspected for precision performance
    • Preset hysteresis (differential) of 20 PPM
    • Photo Sensor to defeat CO2 enrichment at night (dark)
    • Large LED display offers real-time CO2 PPM
    • Orange LED to indicate when CO2 enrichment is active
    • Elevation adjustment feature for improved accuracy
    • Fully integrable with other atmospheric controllers or timers
    • Durable aluminum chassis resists rusting, corrosion and scratching
    • Red illuminated power switch
    • 14 AWG, SJTW rated power cord
    • Two output outlets
    • Operates on 120 VAC at 60 Hz, 12 Amp switching capacity
    • Manufactured in Oregon, USA

    NOTE: Use in a photo sensitive enclosure - The SPC-2 is perfect for monitoring and controlling CO2 enrichment in indoor gardens and greenhouses. This unit was specifically designed so the light emitted from the LED display and 'ACTIVE' indicator is not enough nor in the appropriate spectrum to affect plant growth and/or plant development in any way. You do not need to cover these light sources.
