Green Air Products CO2 Set Point Controller – Model SPC-2

10047

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 equipment plugged into the two power outlets. 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 circuit breaker 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
