Green Air CO2 Set Point Controller Model SPC-1

SPC-1

The SPC-1 is our easiest and most cost effective CO2 monitor and control system and is designed for indoor garden and greenhouses. Just set it and forget it.

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).
