Envelope Humidity Indicator

Envelope Humidity Indicators are devices used to measure and indicate the humidity levels inside an envelope or package. They are part of the supply class Pressure, Temperature, and Humidity Measuring and Controlling Instruments, which includes instruments used to measure and control pressure, temperature, and humidity in various applications.

These indicators are specifically designed to monitor the humidity levels within sealed envelopes or packages. They typically consist of a small, self-contained device that contains a humidity-sensitive element, such as a moisture-sensitive chemical or a humidity sensor. When the humidity inside the envelope exceeds a certain threshold, the indicator changes color or provides a visual indication to alert the user.

Envelope Humidity Indicators are commonly used in industries where it is crucial to maintain specific humidity levels, such as the pharmaceutical, electronics, and food industries. They help ensure that sensitive products or materials are not exposed to excessive moisture, which can cause damage or degradation.

In the supply group Instruments and Laboratory Equipment, which encompasses a wide range of instruments used in laboratories and various scientific applications, Envelope Humidity Indicators are categorized as part of the Pressure, Temperature, and Humidity Measuring and Controlling Instruments class. This class includes instruments such as pressure gauges, thermometers, hygrometers, and other devices used to measure and control pressure, temperature, and humidity in laboratory and industrial settings.
