Digital carbon dioxide sensor FYAD 00-CO2M2 / M3 for assessing the indoor air quality. With ALMEMO® D6 connector. Technical data and functions • Calibrated reference system for CO2 concentration for checking CO2 sensors permanently installed in the building management system (BMS) / room ventilation system (AHU). • Digital sensor with integrated signal processor. All calibration and sensor data are stored in the sensor. • Unique auto-calibration procedure (without fresh air supply): aging effects are automatically compensated. • With filter cap to protect against dust and dirt. • Automatic compensation with built-in digital temperature and barometric pressure sensor. • Low power consumption. Long-term measurements with ALMEMO® data logger in sleep mode; only for current instrument types with sleep delay. • 3 primary measurement channels (real measured variables): carbon dioxide concentration, air temperature, air pressure. 03/2026 • We reserve the right to make technical changes. • Assessment of air quality for checking demand-oriented ventilation in recreation and work rooms, including classrooms, lecture halls, day care centers, meeting rooms, event rooms, production halls, health care facilities, public transportation. • In combination with an ALMEMO® data logger, the measured values are continuously recorded with date, time. Based on the stored data, a differentiated analysis of the air quality during the room usage times is possible. • Simultaneous measurement of air temperature as a criterion for assessing the quality of stay (comfort) in the rooms. concentration • Quantitative measurement of CO2 in ppm. Differentiated decision for concentrations near the quality levels 1000 ppm and 2000 ppm. On request: calibration of the sensor (traceable) by an accredited cal

Room air conditionsTechnical Data Sensor: 2-beam infrared sensing element. Non-dispersive infrared technology _(NDIR)._ Automatic compensation of pressure and temperature dependence of CO2 measurement with the built-in sensors. Accuracy: ±(50 ppm +3 % of measured value) Nominal conditions: 25 °C, 1013 mbar Switch-on time (initialization): 15 s Response time t63: 140 s Measuring interval: fixed 15 s as exponential moving average over 60 s (= 4 instantaneous values 15 s).
