Green Air CO2 Set Point Controller model SPC-1

Keep CO2 levels just where they want them! The Green Air Set Point Controller (SPC-1) is designed to easily monitor and control CO2 enrichment in your indoor growing area or greenhouse. It samples the air and determines the concentration of CO2 in PPM which is shown real-time on a large, easy-to-read LED display. It's easy to install and operate. Following your set point values (desired PPM CO2 and elevation), the SPC-1 will activate/de-activate the CO2 enrichment equipment plugged into the 6' piggy back cord. Just set it and forget it! The Set Point Controller is factory calibrated and inspected for precision performance. It even has an elevation adjustment to fine-tune accuracy at a preset differential of 20 ppm. This extremely accurate controller has a built-in photosensor to prevent unneccessary CO2 enrichment during lights-off. There's a orange LED to indicate when CO2 enrichment is active, as well as a red illuminated power switch. Manufactured in Oregon, USA, the Set Point Controller provides a wall-mountable, durable black anodized aluminum chassis that resists rusting, corrosion and scratching. It operates on 120 VAC at 60 Hz, 12 Amp switching capacity, and is fully integrable with other atmospheric controllers or timers.
