Abstract

PURPOSE: To make it possible to measure the atmospheric circumstances to exert influences upon metal corrosion by recording moisture capacity higher than a preset level in a moisture recorder.
CONSTITUTION: An integrator 11 is connected with a moisture recorder 3, which in turn is connected through a moisture meter 2 with a detecting element 1, through a circuit 12 for subtracting the voltage corresponding to a preset moisture from the output of the moisture meter 2. Thus, the moisture capacity higher than 80% of the output of the meter 2 is integrated and indicated, and the moisture capacity higher than 80% corresponds considerably to the corrosion of metal so that the atmospheric circumstances exerting influences upon the metal corrosion can be easily measured. Incidentally, effects can be attained if a voltage-frequency converting circuit 14, an electromagnetic counter, a pulse motor or a stepping motor 15, and a watch type indicator 16 are consecutively connected with the moisture meter 2.
