Product catalog summary

Overview: The EE850 is a CO2 and temperature sensor designed for duct mounting, suitable for demand-controlled ventilation and building automation. It features a CO2 measuring range up to 10,000 ppm and a temperature range of -20 to +60 °C (-4 to +140 °F).

Key Features:

Long-Term Stability: Utilizes E+E dual wavelength NDIR CO2 sensor for high stability and pollution resistance.
High Measurement Accuracy: Factory-adjusted for precise CO2 and temperature readings across the entire temperature range.
Functional Design: Easy installation with a functional enclosure that allows air flow through the probe to the CO2 sensing cell.
Outputs: Provides analogue and digital outputs, including RS485 interface with Modbus RTU protocol.
Configuration: Easy configuration and adjustment via optional stick and free PCS10 software.

Technical Specifications:

CO2 Measurement: Dual wavelength NDIR technology, accuracy of < ±(50 ppm +2% of measured value) for 0-2,000 ppm and < ±(100 ppm +5% of measured value) for 0-10,000 ppm.
Temperature Measurement: Range of -20 to +60 °C with an accuracy of ±0.3 °C at 20 °C.
Response Time: CO2 response time t63 <100 s, temperature response time t63 <50 s.
Power Supply: 24 V AC ±20% or 15-35 V DC, with a typical current consumption of 15 mA.
Environmental Conditions: Operating range of -20 to +60 °C, 0-95% RH non-condensing.

Calibration and Certification: The E+E calibration laboratory offers traceable calibration certificates in accordance with DIN EN ISO/IEC 17025, ensuring measurement traceability to the International System of Units (SI).

Dimensions and Installation: The sensor includes a mounting flange and is available in two probe lengths (50 mm and 200 mm). It is designed for easy and fast mounting with external mounting holes and bayonet screws.

Ordering Information: The EE850 is available in different configurations, including CO2 only or CO2 + temperature models, with various output and probe length options.

Contact Information: E+E Elektronik provides contact details for its headquarters in Austria and subsidiaries in various countries for further inquiries and support.
