Abstract. The design of the thermal gradient measurement instrument prototype that has been done previously requires field testing. This test aims to see the ability of the prototype instrument indirect measurement tests in geothermal fields. The method used in testing is to compare the results of temperature measurements on the prototype instrument with temperature measurements using the MAE A5000T instrument from previous research in Padang Cermin. The calculation of the thermal gradient is carried out automatically by the system in the prototype using the least-squares technique. The measurement results show that there is temperature alignment, especially in the manifestation area. The temperature distribution map indicates a clustering pattern that shows the relationship between hot fluid flow, especially in the westeast direction. The hot fluid connectivity is interpreted as a geological structure or permeable zone in the manifestation area. The results of the thermal gradient measurement also show a high gradient pattern in the geothermal manifestation area. Besides, the distribution of low-temperature values in the three layers also indicates the source of the surface water fluid flow, which is in line with the direction of the top of the mountain. These findings reinforce the indication that the peak of Mount Ratai dominates the meteoric water recharge source. These findings indicate that the prototype of this thermal gradient measurement instrument can be used in geothermal fields.
