Description

Description The Kele KCOC Series Combination Carbon Monoxide Sensors pair a CO sensor with a CO2, RH, or VOC sensor in the same enclosure-reducing installation time and space required. The unit provides visual indication and analog output of CO levels in enclosed spaces such as schools, offices, malls, and theaters. Each transmitter is available with either a 0-10V or 4-20 mA and is scaled from 0-200 ppm of CO and all outputs will use the same output. They are designed with push button calibration and an easily accessible calibration port for field maintenance. Optional audible alarm indication, LCD display, or relay output is available. The optional relay option closes at 30 ppm and opens at 20 ppm, and the audible alarm will sound at 50 ppm.
