The SPC-1 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-1 WORKS: The SPC-1 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-1 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).
See diagram at right: This is like a thermostat for your CO2. Of course it is not a thermostat but it is as simple to use as that. Just set your desired CO2 level and there you have it. It's just that easy. The SPC-1 monitor uses infrared technology to turn CO2 equipment on and off based on a 20 ppm variable and not allow it to operate at night. In this diagram it is plugged into a CT-DH-3 atmospheric controller to coordinate with ventilation but you could just as well use it without the CT-DH-3 as a stand alone CO2 controller.

NOTE: Use in a photo sensitive enclosure - The SPC-1 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.
