Continuous Gas Monitoring Alarm SЗ-Ai for CO and Hydrocarbon Detection

The ??-Ai gas alarms are designed for continuous automatic monitoring of carbon monoxide or hydrocarbon gas concentration in the air and signalling of exceeding the set threshold values. Operation principle of ??-Ai gas alarms: <ul> <li>- hydrocarbon gas alarms - semiconductor;</li> <li>carbon monoxide alarms - electrochemical. The sampling method is diffusion.</li> </ul>When the concentration exceeds the threshold level, sound, light and control signals are generated in accordance with the logic of the signallers operation.
