moisture indicating humidity card pouch

Introduction

Humidity Indicator Cards Humidity indicator card (also known as HIC, humi Kamoer Humidity Indicator 10-60% 6 Dots dity indicator card, moisture indicator) is a card on which a moisture-sensitive chemical is impregnated such that it will change color when the indicated relative humidity is exceeded. This item is an inexpensive way to quantify relative humidity levels inside sealed packaging.

Humidity Indicator Card can easily measure the relative humidity inside the sealed package to allow a quick and low cost inspection of whether the humidity level is unsafe, and it is reusable!

This Indicator Card has 6 indicating spots (10%-60% RH), they change from Yellow (dry) to Blue (wet). A great tool to assist you in keeping your valuables protected!

The number 10, 20, 30, 40, 50, 60 inside the circle indicates the humidity percentage of 10%, 20%, 30%, 40%, 50%, 60%.
