90 ... 100 %RS
Temperature
Measurement range
Accuracy at +20 °C (+68 °F)
1) Note that the temperature range for specified measurement accuracy differs between
measurement parameters. Measuring a parameter outside its temperature range does not
damage the sensor, but results in reduced accuracy for that parameter.
