Description
The GREYSTONE CMD5B4100 is designed for dependable indoor air-quality monitoring, specifically to detect harmful carbon monoxide (CO) levels before they become dangerous. Its electrochemical sensor delivers accurate CO detection over a configurable range (up to 500 ppm), with output options (4–20 mA or 0–5 / 0–10 V) that make it easy to integrate into building management or HVAC systems. The on-board LCD provides real-time CO concentration readings, so facility managers or staff can instantly see current air conditions. If CO rises above safe thresholds, the built-in audible alarm buzzer and optional relay alert ensure timely response, giving you crucial time to ventilate or evacuate.
Because it comes in a rugged, IP65 / NEMA 4X-rated enclosure, the detector remains durable in commercial or industrial environments — from offices and shops to warehouses or plant rooms. Compared to basic CO alarms, the CMD5B4100’s analog output, selectable measuring range, and robust build provide far greater flexibility and reliability. Whether you’re managing a large facility, a school, a theater or a hospital, this detector helps safeguard occupants’ air quality and peace of mind.
