ProTech 8505 Commercial Carbon Monoxide Monitor

The ProTech 8505 Commercial Carbon Monoxide Monitor is battery powered with an LCD digital readout, backlight, and state-of-the-art electrochemical sensor. The current carbon monoxide level detected from 10 to 500ppm is continuously displayed. The memory recall feature displays highest level detected, time duration and how long ago. This fixed CO monitor is designed to activate audible and visual alarm signals before the immediate area reaches the Recommended (REL) and Permissible (PEL) Time Weighted Average (TWA) carbon monoxide Exposure Limits established by the National Institute for Occupational Safety and Health (NIOSH) and Occupational
Safety and Health Administration (OSHA). The Sensor Life Monitor feature alerts you when sensor life has expired. The ProTech commercial carbon monoxide monitor includes a one year factory warranty.
