Employing non-dispersive IR technologies, Model IRCO2 meets requirements of Demand Controlled Ventilation systems. Unit utilizes 2-channel detector and pulsed emitter with burst mode that only energizes emitter 188 ms out of every 30 sec measurement cycle, minimizing power consumption. Generating signal passively by measuring absorption of IR light through gas, sensor eliminates degradation concerns. IRCO2 delivers highest sensitivity in 4.26 micron wavelength region and achieves 25 ppm accuracy.
