What are Humidity Indicators?

A humidity indicator is an object, device or mechanism that visually signals the relative humidity level of its given environment.

How Do Humidity Indicators Work?

Humidity indicators and sensors employ chemical change or electronic sensing to measure humidity.

Why Use Humidity Indicators and Sensors

In order to ensure that the contents of sealed spaces remain in good health without exposing a container’s contents to potential contamination or damage.

Humidity indicators enable quick, easy visual inspection of the humidity level of an enclosed environment from the outside.

Often in the aerospace and many other industries, an enclosure is sealed to protect the contents inside, either for shipping and transit, or permanently if the contents are integral to the operation of the item. These contents frequently include electronics, optics, perishables, or items that may otherwise be negatively impacted when in contact with debris or moisture above a certain level

Industry Applications

Humidity indicators and sensors are used throughout many industries to quickly and easily monitor the health of sealed contents. For example, humidity indicators may be used on military munitions boxes, or on storage and shipping containers for infrared optics assemblies like those found on many imaging satellites. A few examples include:

  • Monitoring the internal humidity levels in power transformers
  • Monitoring gas streams post desiccation and pre-combustion in energy plants
  • Monitoring humidity levels around pharmaceuticals in storage and during transport
  • Monitoring humidity levels around machine components during storage and transport
