How works the ENOX?
Using an electrochemical cell means that the ENOX combines good sensitivity at low gas concentrations with high range capability and excellent stability. Electrochemical cells contain an electrolyte that is gradually consumed during use, influenced mostly by the duty cycle, ambient temperature and humidity. Therefore, the Sensor Module requires replacement / recalibration every 6 to 12 months to ensure accuracy of response. The sensor modules are pre-calibrated plug-in units which can be quickly and conveniently replaced, which means calibration gases are not required. Replacement sensor modules are available from Tunnel Sensors.
The ENOX is an intelligent sensor with 4-20 mA output and the option of RS485 serial communication protocols. It has two visual output alarm signals for GENERAL alarm and HIGH alarm. Default values are entered during manufacture and these can be adjusted to preferred values.
