How much are DO readings effected by temperature change with the LDO Model 2 sensor?
Temperature change and how they effect the LDO Model 2 DO sensor readings.
The DO reading is very strongly influenced by temperature. The DO value will change by about .25 ppm per degree centigrade. The LDO probe monitors temperature using a thermistor that is located on the end of the probe underneath the sensor cap. Since the thermistor is potted into the probe, the probe will have to be replaced if the temperature reading is incorrect.
