Discover the EE800, a cutting-edge sensor designed for optimizing demand-controlled ventilation and building automation in both residential and commercial environments. This multifunctional device expertly combines CO2, temperature, and relative humidity measurements, offering a comprehensive solution for monitoring indoor air quality. Additionally, it calculates the dew point temperature, providing a complete assessment of your indoor climate conditions.

Equipped with the advanced E+E dual wavelength NDIR CO2 sensor, the EE800 stands out for its resistance to pollution, minimal aging effects, and exceptional long-term stability. This ensures not only accurate but also reliable readings over extended periods. The sensor undergoes a thorough multi-point CO2 and temperature factory adjustment, ensuring top-notch accuracy across its entire operational range.

Featuring both analogue outputs and an RS485 interface, the EE800 extends its versatility with additional physical quantities available via Modbus RTU or BACnet MS/TP, including absolute humidity, mixing ratio, enthalpy, frost point temperature, and water vapor partial pressure. An optional display alternates between measured values for convenient monitoring.

The EE800’s installation and maintenance are streamlined with its innovative snap-on design, allowing for quick replacement of the active front part while keeping the wiring intact. This design also shields the device’s electronics from potential construction site pollution during installation. The sensor is easily configurable and adjustable, supported by an optional USB configuration adapter and the free EE-PCS Product Configuration Software.

Key technical specifications include a CO2 measuring range of 0 to 2000/5000 ppm, temperature accuracy of ±0.3 °C for RS485 interface or voltage output, and a relative humidity working range of 10 to 90 %RH. The device operates on a 24 V AC ±20 % or 15 – 35 V DC power supply, with a typical current consumption for analogue output of 14 mA plus output current.

Housed in a durable polycarbonate enclosure, the EE800 is available in two sizes to comply with regional standards and features an IP30 protection rating. It adheres to EN 61326-1 and EN 61326-2-3 electromagnetic compatibility standards, ensuring seamless operation alongside other electronic devices.

Originally valued at $595, this high-performance sensor is now available for auction. The final location for pickup by the winning bidder will be disclosed at the close of the auction.
