  _Templates Conex DIA-G

Gas warning unit for chlorine, chlorine dioxide, ozone, ammonia and hydrochloric acid
Optimum safety – minimum labour input: The Conex DIA-G safety system monitors the concentration of the gases chlorine, chlorine dioxide, ozone, ammonia and hydrochloric acid in the air of storage rooms. It is equipped with a range of functions providing the users with optimum safety combined with minimum labour input. One unit can use two interconnected sensors to monitor two different gases, two different gas concentrations or two different gas storage rooms in parallel.

FEATURES AND BENEFITS
Optimum safety: Thanks to permanent sensor monitoring, the alarm relay and the possibility of backup operation (uninterrupted current supply) by connection of an external buffer battery
Very short response time in case of a sudden change of the gas concentration
Long service life of the sensor element – without necessity of maintenance
Sensor recognition and auto-calibration, monitoring of the lifetime of the sensor
Internal CAN bus interface for the connection of potentiostatic sensors using bus lines with a total length of max. 500 m
External CAN bus interface for the connection of Conex DIA-G to the visualising software AquaVision 2 or to PLC
