DatasheetEE8915 C02 Sensor for Railway Applications

EE8915 CO2 Sensor for Railway Applications EE8915 measures reliably CO2 concentration in harsh environment and complies with the relevant railway standards. Outstanding Accuracy and Long-Term Stability A multiple point CO2 and temperature (T) adjustment procedure leads to excellent CO2 measurement accuracy over the entire T working range -40…+60 °C (-40…+140 °F). The active compensation with on-board sensors leads to best CO2 measurement accuracy independently of weather conditions, altitude or temperature. The E+E dual wavelength non-dispersive infrared (NDIR) measurement principle compensates...

Features Accredited Traceable Calibration Certificate Internationally recognised certificates for the calibration of measuring instruments from accredited laboratories document the traceability of the measurements to the International System of Units (SI). The E+E Elektronik calibration laboratory Type T1 offers two levels of traceable calibrations. ▪ As a Designated Institute (DI) of the Republic of Austria, the E+E calibration laboratory maintains Austria’s national measurement standards for humidity, dew point temperature, air velocity and CO2. This authorises the E+E calibration 39.8 (1.57)...
