Description
The Dwyer CMT-200 is designed to deliver dependable carbon monoxide monitoring, whether in underground parking garages, mechanical rooms, maintenance facilities, or other enclosed spaces. Its electrochemical sensor — replaceable and rated for years of dependable service — continuously measures CO concentration from 0 to 200 ppm. When CO rises, the sensor output (either 4–20 mA or 2–10 V, as you select) changes proportionally. This analog output is ideal for integration with building automation systems (BAS), ventilation controls or alarm systems, enabling automated ventilation or alert triggers rather than relying solely on manual checks.
With a rapid response time (less than 45 seconds to reach 90% of final reading), CMT-200 ensures early detection — critical in enclosed or poorly ventilated areas. Its durable UV-resistant polycarbonate housing guards against environmental wear, while the flexibility of replaceable sensors and selectable outputs means it adapts to many facility setups. Compared to basic CO alarms or less flexible detectors, the CMT-200 offers robust integration, long-term reliability, and professional-grade sensing — suitable for commercial buildings, basement garages, workshops, or any space where CO accumulation poses a risk.
