Non-Dispersive Infra-Red (NDIR) CO2 Measurement with ABC Logic
The GS-N300-W is essentially the GS-N100-W package with the addition of a relative humidity and space temperature sensor.
CO2 Measurement: Provides the CO2 level in ppm via the network connection
System Status Alarm: Yes
Baud Rate, Protocol and Addressing: DIP switch
End of Line Termination: Jumper
Important: Modification of the factory default settings requires that power is cycled to the device. It is recommended that each device is bench configured prior to installation OR settings are provided at the time of order so that the device can be factory configured prior to shipment.
