CO2 sensor

A multiple point CO2 and temperature adjustment procedure leads to excellent CO2 measurement accuracy over the entire temperature working range, ideal for use in agriculture or outdoors for instance.

The CO2 sensor is designed for use in harsh, demanding OEM applications. A multiple point CO2 and temperature adjustment procedure leads to excellent CO2 measurement accuracy over the entire temperature working range, ideal for use in agriculture or outdoors for instance. The sensor incorporates the dual wavelength NDIR CO2 sensor, which compensates for ageing effects, is highly insensitive to pollution and stands for outstanding long term stability. The measured data range of up to 10000ppm is available on the Modbus or on the E2 digital interface. An optional kit facilitates easy configuration and adjustment. The measurement interval can be set according to the application requirements, by this the average current consumption can be reduced to 120A for battery-operated devices.
