  • Features
    eYc GS45 is a non-dispersive infra-red(NDIR)CO2 sensor module designed specifically for incubator application. With pigtail wire connections, the GS45 comes with internal and external mounting options.
    The sensor module is powered with DC 12 V and it converts the measurement into a linear voltage signal(0 … 5 V corresponding to 0 … 20 vol.% CO2)or RS-485(Modbus communication corresponding to 0 … 30 vol.% CO2)
    The GS45 also comes with simple maintenance features. The BC wiring connection allows the user to perform a quick background calibration(BC)(Sensor exposed to the fresh-air condition)

  • Applications
