ENOM - Electrochemical No Monitor for Tunnels

The ENOM is a compact electrochemical gas monitor to measure the concentration of Nitric Oxide (NO) within tunnel environments. The ENOM tunnel monitor measures the concentration of Nitric Oxide (NO) within an ambient environment such as road and rail tunnels or other industrial applications. These measurements can be used as part of an air quality management system for ventilation control. The ENOM is a fixed sensor, which uses an electrochemical cell for NO detection. The ENOM consists of a Sender Unit and a ‘plug-in’ Sensor Module, which are mounted together on the wall or ceiling of the tunnel. The Sensor Module is pre-calibrated and stores all necessary data relating to type identification, sensing range and specific calibration. This data is automatically recognised by the Sender Unit when the module is fitted.
