Abstract
The invention discloses a humidity indicator card. A humidity detecting apparatus comprises a half-folded card. An inner side of one surface of the half-folded card is fixedly pasted with an absorption layer, which is coated with humidity colour-changing agent. An inner side of the other surface of the half-folded card is fixedly pasted with a humidity colour-changing agent colour-changing colourimetric card. The humidity indicator card of invention has a simple structure and can detect the degree of humidity change.
Description
Technical field
The present invention relates to a kind of humidity detector, relate in particular to a kind of humidity indicating card.
Background technology
For the food stored or other article to moisture-sensitive, usually need place drying agent, and monitor drying agent at any time and whether lost efficacy, whether airborne moisture, humidity exceed standard.Homemade at present or family's simple and easy humidity detector commonly used generally all can only be monitored humidity and changed, but the degree of its variation can't detect.
Summary of the invention
To the problem that above-mentioned prior art exists, the object of the invention is to provide a kind of humidity indicating card, and simple structure can detect the humidity intensity of variation.
Technical scheme of the present invention is: a kind of humidity indicating card; The card that comprises a doubling; The medial surface cementation of a wherein foldable plane of card has absorption layer, also is coated with the humidity colour-changing agent on the absorption layer, and the medial surface of said another foldable plane of card is pasted and is fixed with humidity colour-changing agent variable color colorimetric card.
The invention has the beneficial effects as follows: the humidity colour-changing agent absorbs behind the airborne moisture can variable color gradually, and the degree of its variable color has characterized airborne liquid water content, through with the comparison of colorimetric card, can draw to simple, intuitive the humidity intensity of variation.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Embodiment
As one embodiment of the present invention, as shown in Figure 1, a kind of humidity indicating card; Comprise the card 1 of a doubling, card 1 can be paper card or plastic clip etc., and the wherein medial surface cementation of a foldable plane 11 of card 1 has absorption layer 2; Absorption layer 2 can be selected the strong filter paper of absorbability, cloth etc. for use; Also be coated with humidity colour-changing agent 3 on the absorption layer 2, humidity colour-changing agent 3 can be selected the reagent of cobalt chloride commonly used and so on for use, and the medial surface of said card 1 another foldable plane 12 is pasted and is fixed with humidity colour-changing agent variable color colorimetric card 4; Change color and corresponding humidity are arranged on the humidity colour-changing agent variable color colorimetric card 4, can draw the humidity intensity of variation through itself and 3 contrasts of humidity colour-changing agent.
