EC-500
Indoor Carbon Monoxide Diffusion Gas Monitor
Datasheets • Manual
RKI’s Model EC-500 is an indoor monitor that detects Carbon Monoxide (CO) with a range of 0-150 ppm. It’s a sleek low profile design which lends itself to laboratory or commercial applications. The EC-500 comes ready to operate with a simple wall mount bracket and 10 foot power cord. If Carbon Monoxide is present, the user is notified by an audible alarm tone and multicolored LED display.
The EC-500 uses a fast responding low-cost plug-in style electrochemical sensor. This long life sensor is field-replaceable with no special tools required.
