EE850 CO₂ and Temperature Sensor

The EE850 sensor is a high-accuracy, dual-function device designed to monitor both CO₂ concentration and temperature. Optimized for HVAC and industrial applications, the EE850 features a duct-mountable form factor with a robust IP65-rated enclosure. It leverages dual-wavelength NDIR technology for precise CO₂ measurement and incorporates temperature compensation to ensure stability over time. Specifications CO₂ Measurement Technology Dual-wavelength Non-Dispersive Infrared (NDIR) Temperature Sensor Integrated high-accuracy digital sensor CO₂ Measuring Ranges 0–2,000 ppm or 0–10,000 ppm CO₂ Accuracy ±(50 ppm + 2%) for 0–2000 ppm; ±(100 ppm + 5%) for 0–10,000 ppm Temperature Range -20°C to +60°C Temperature Accuracy ±0.3 °C @ 20°C CO₂ Response Time < 100 seconds at 3 m/s airflow Temperature Response Time < 50 seconds Output Options Analog: 0–10V or 4–20mA; Digital: RS485 with Modbus RTU Baud Rates Supported 9600 / 19200 / 38400 Power Supply 24V AC ±20% or 15–35V DC Typical Current Consumption 15 mA + output load Peak Current Up to 350 mA for 0.3 seconds Minimum Air Speed Required 1 m/s Enclosure Protection IP65 for electronics; IP20 for probe Material Polycarbonate (UL94 V-0 rated) Operating Conditions -20°C to +60°C; 0–95% RH (non-condensing) Mounting Duct mount with bayonet lock and included flange Configuration Tool USB-C configuration stick with PCS10 software
