The minimum duration until a measured value is assessed as stable is the mon-
itored time interval. The actual duration is mostly longer.

5.1.2 Measuring the temperature

For reproducible D.O. measurements, it is essential to measure the tempera-
ture of the test sample.
The temperature is automatically measured by the temperature sensor
(NTC30 or Pt1000) integrated in the sensor.
The CellOx 325 / StirrOx
integrated temperature sensor.
