KCOP Series CO Carbon monoxide steel enclosure sensor

Previous Page

The KCOP Series Carbon Monoxide Detectors are designed to monitor CO levels in parking garages, loading docks, factories, warehouses, transportation terminals, and more. Models are available with 4-20 mA output or dual relay output for designated warning and alarm CO levels. The detector features a tri-color LED which illuminates green to indicate the unit is powered and functioning properly. On the relay output models, the LED will illuminate amber and red for warning and alarm status. A red LED indicates that the sensor needs to be replaced. The microprocessor-based electronics are housed in a rugged, steel enclosure with hinged- or screw-covers. A low-temperature option is available for colder climates.
