KS-7D Low Cost Carbon Monoxide Detector

The KS-7D is a low cost, wall-mounted detector typically installed in working environments to check against Carbon Monoxide levels. It suitable IAQ monitoring in offices, car-parks, laboratories or other commercial applications.

It has a large LCD display for quick readout of the Carbon Monoxide level.

Audible and visual alarms alert occupants of low oxygen levels. Analogue and digital outputs are also available for connection to external devices (exhaust fans etc.) and/or supervisory systems.
