EE820 CO₂ Sensor for Demanding Applications
The EE820 CO₂ sensor is designed for accurate and long-term stable measurement of carbon dioxide in harsh and demanding environments. It is ideal for applications such as greenhouses, livestock barns, and hatcheries, where exposure to dust and humidity is common. With dual-wavelength NDIR sensing technology, auto-calibration, and temperature compensation, the EE820 ensures high accuracy over time. The sensor features an IP54-rated enclosure and provides analog outputs for easy integration with control systems. Configuration and adjustment can be done via a USB-C interface using the free PCS10 software.
