CO-Guard (photo) is a compact, user-friendly monitor for compressed-air-line carbon monoxide (CO). The instrument incorporates a rotameter for confirmation of proper airflow, a backlit digital display and a highly specific electrochemical CO sensor for trouble-free and reliable operation. With simple use and installation, CO-Guard is designed for use in a wide variety of applications, ranging from automotive paint-spray operations to wood finishing. This monitor can be used in virtually any commercial or industrial process that requires CO monitoring of compressed breathing air for personnel working in such operations. The device covers a detection range of 0 to 50 parts per million (ppm) CO, with three adjustable alarms (5, 10 and 20 ppm CO). — Enmet Corp., Ann Arbor, Mich.
