Macurco CD-6B Series Carbon Dioxide CO2 Fixed Gas Detector, 12-24V, White

Protect staff, product and facility air quality with the Macurco CD-6B Carbon Dioxide (CO2) fixed gas detector — a commercial-grade monitoring solution designed for reliable, low-maintenance CO2 surveillance. The CD-6B uses infrared sensing to deliver accurate detection across a 0–5% (0–50,000 ppm) range, reducing nuisance alarms common with other technologies. Low-voltage 12–24V (AC/DC) operation and three separate alarm relays let you configure staged responses or directly interface with fire, burglar, and building automation panels for faster incident management.

Operators benefit from a clear digital display and onboard buzzer for local notification, plus duct-mount compatibility and recommended coverage of 900–5,000 sq. ft. to suit greenhouses, restaurants, refrigeration rooms, pharmaceutical and industrial environments. Wired connectivity and commercial construction make the CD-6B a dependable choice for security and safety teams focused on continuous air monitoring and regulatory compliance. Backed by a 2-year limited warranty and US manufacturing, it’s built for mission-critical deployments.
