Annotation. The article presents the results of operational control of the accuracy of underground water temperature measurements obtained using three Levelogger Edge devices that have different operating periods. Underground water temperature measurements were performed by the authors in the production well No. 24 of the Elizovsky field of underground drinking water at a depth of 7.5 m. the Analysis of research results showed: a) all measurement results obtained using separate devices No. 1-3 are highly precise; b) there is a statistically significant systematic discrepancy between the results of measurements obtained using separate devices No. 1–3. It is assumed that the suppliers of Levelogger Edge devices do not perform their initial verification.

Key words: groundwater temperature, Levelogger Edge device, water temperature measurement error characteristics, underground drinking water deposit.
