They readily detect changes in the humidity of the space being monitored by using a colour change indicator paper which turns from blue to pink as the humidity increases, and turns back to blue when the humidity decreases. The indicator solution used is water soluble and therefore humidity indicator papers should not be placed in direct contact with water or steam or exposed to extremely high humidity's for protracted periods of time. Also strong solvents such as ammonia fumes will cause the bleaching of the colour change dye and lose colour reversibility.</ins></div></td></tr> <tr><td class="diff-marker" data-marker="−"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #ffe49c; vertical-align: top; white-space: pre-wrap;"><div><del style="font-weight: bold; text-decoration: none;">* Improper use </del>of <del style="font-weight: bold; text-decoration: none;">this page will lead </del>to <del style="font-weight: bold; text-decoration: none;">permanent banning</del>. </div></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div><ins style="font-weight: bold; text-decoration: none;">Most of these [[Indicators]] </ins>can <ins style="font-weight: bold; text-decoration: none;">be fitted with a desiccant cartridge which will adsorb any moisture entering </ins>the <ins style="font-weight: bold; text-decoration: none;">equipment during its use.

Humidity indicators consist of a special absorbent paper.

The colour reaction of the humidity indicator card, however, can be delayed through low temperature levels during winter time, a lack of air circulation between humidity indicator and drying agent or foils not suitable for the purpose.</ins></div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div> </div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div> </div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div><ins style="font-weight: bold; text-decoration: none;">==Accuracy==</ins></div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div><ins style="font-weight: bold; text-decoration: none;">The humidity indicator cards are small</ins>-<ins style="font-weight: bold; text-decoration: none;">sized, easy to handle and inexpensive.
