90
approx. 60 s (with increasing and decreasing concentration)
12.2.3 Measured value resolution of sensor
0.01 mg/l (ppm)
12.2.4 Maximum measured error
±2 % or 200 µg/l (ppb) of value measured (depending on which value is higher)
LOD (limit of detection)
1)
LOQ (limit of quantification)
1)
0.022 mg/l (ppm) 0.072 mg/l (ppm)
1) Based on ISO 15839. The measured error includes all the uncertainties of the sensor and transmitter (electrode
system). It does not contain all the uncertainties caused by the reference material and adjustments that may have
been performed.
