  • Product Description

    RKI’s Model EC-600 is an indoor, standalone monitor that detects Carbon Monoxide (CO) with a range of 0-150 ppm with 1 ppm increments. It’s sleek, low-profile design is equipped with a unique tri-color display, which changes color as Carbon Monoxide levels reach each alarm level. This version operates at 115 VAC. The EC-600 has two preset alarms, and comes ready to operate with a simple wall mount bracket and 10 foot power cord in its AC version. If Carbon Monoxide is present, the user is notified by an audible alarm tone and the multicolored LED digital display. The EC-600 uses a fast responding low-cost plug-in style electrochemical sensor. This long life sensor is field replaceable with no special tools required. The sensor can also be remotely mounted with an optional remote sensor cable.
