If you cannot leave the probe in the tube, plug the tube using a rubber
plug (233976). This means you will have to insert the probe when taking
the measurement, and wait for about 30 minutes for stabilization.
It is recommended that you leave the probe into the tube as this ensures
the best possible reliability of the readings.
