Using the same hole for the reference thermometer and the test probe may have

better results. This however requires switching the probes which takes more

time. One must allow a few minutes after inserting the probes for the tempera

tions along the length of the well, best results are obtained when comparing

probes of similar construction and inserting them the same depth into the well.
