The invention relates to a humidity measuring material, characterized in that a liquid adhering member such as filter paper or cloth is immersed therein for 2 to 3 seconds, and then dried at a temperature of 70 to 80°C, wherein the reagent (composition) ) changes in humidity, the purpose of this is to determine the humidity around the humidity measuring material by observing its discolored state.

After drilling a hole in a building material, when inserting a humidity measuring material (filter paper for coloring) into the hole, the material for measuring humidity (filter paper for coloring) changes from orange to yellow ocher to light green1 according to changes in humidity. The color reversibly changed from green to black edge to purple, and as it dried, the color changed reversibly from purple to black edge to green to pale green to ocher to orange.The humidity inside the building material was determined by looking at the state of the color change.

It is characterized by being dipped for ~3 seconds and then dried at a temperature of 70~80°C, so it can be used not only for building materials made of concrete IJ but also for indoors, greenhouses, warehouses, and other concrete surfaces. It has characteristics such as being able to easily determine the humidity of the product, and reversibly changing color (the dry state can be determined more easily by the discolored state, so it is possible to determine at a glance which dry state should the work be started from). It is something.
