The Duomo CO100Ar Carbon Monoxide Sensor is a precision instrument for accurate CO detection in commercial, industrial and public areas. Using advanced electrochemical sensor technology it provides real-time CO monitoring and integrates with Duomo gas detection control panels for safe management.
With a 4–20mA signal output and Time Weighted Average (TWA) function the CO100Ar detects CO levels instantly and alerts when gas concentrations remain above threshold for example 30ppm for 120 minutes. Ideal for boiler rooms, car parks, mechanical plant areas and other areas where CO build up is a serious risk.
Built to last the sensor has IP66 protection for the enclosure and IP65 for the sintered head so it will perform in harsh environments. Certified to EN50291 for toxic gas and CE marked (No. 96125) it meets European standards for professional gas detection systems.
The CO100Ar is a high-accuracy, industrial grade CO sensor for long term stability and integration flexibility. Its TWA capability, wide compatibility and IP66 design make it the choice for professional CO detection in commercial and industrial sites.
