|Humidity Indicators (also known as relative humidity indicators, RH indicators, moisture indicators, colour changing discs) allows you to monitor humidity levels inside packaging, containers, or other enclosures. When the relative humidity (RH) exceeds a certain level, the cards will change colour to warn you to check the product quality.
Humidity Indicator Card sensors are inexpensive and ideal for applications where there is no need to monitor the humidity level from the outside.
However, if there is a need to monitor the humidity level from the outside, Humidity Indicator Plugs are ideal as the sensor can remain inside the packaging, giving you an accurate reading, where the data is viewable outside the packaging.
Stream Peak’s Humidity Indicators are reversible and reusable – the indicator will turn back to its original colour once the relative humidity level has reduced to the expected level.
