humidity and temperature meter standard probe Vaisala HM41. Secondly, in March 2021, the surface protection system, described in Section 3.3, was applied to the starting of the column of Pier P8. The coated area encompassed some of the above-mentioned measurement locations (L2 and L3). Moreover, to obtain a more comprehensive set of data concerning the effect of the coating on the concrete moisture level, 25 new holes, for measuring temperature and relative humidity in concrete, were made throughout the test area, seven of which on an area without the coating. The coating system was applied to the four sides of the column, in a strip of approximately 2 meters high, as illustrated in Fig. 2. The temperature and relative humidity readings were taken using a Vaisala HM40 indicator, with a quick connection adapter, and Vaisala HMP40S humidity and temperature snap-on probes.
