The CD-6B  is a low voltage (12-24 VAC/VDC) monitor that provides three alarm levels using three separate relays for controlling external devices. As a result of the three-alarm levels, this helps to maintain acceptable levels of Carbon Dioxide in the beverage and food industries, greenhouses, pharmaceutical, and other chemical processing or other commercial applications. The CD-6B can be used as a stand-alone unit or connected to a burglar/fire panel. The monitor has a high range of 0-5% by vol. (0-50,000PPM) with a recommended coverage area of 900 – 5000 sq. ft.  – ETL Listed
