What is the humidity indicator?
The humidity indicator is a device that measures the amount of water vapor in the air. These devices move in complexity and functionality from simple cards impregnated with chemicals sensitive to humidity to complex sensor and microprocessor systems. Most of them are used to determine the levels of moisture in areas or environments that are sensitive to excessive air humidity or significant fluctuations in moisture levels. These include shipping containers, packaging for destruction or sensitive goods and electronic equipment. There are three common presentations of moisture indicators: chemical, electronic or dialing.
In different degrees, the humidity is a constant environmental factor even in the driest and coldest climate. Generally moisture present in the air does not pose any serious threats, but in certain environments it can be problematic. When monitoring the levels of moisture, it becomes a problem, the humidity indicator of useful information about the amount of water vapor suspended in the air. ExIt I will use many different examples of moisture indicators generally to use all that fall into three basic categories. As already mentioned, these are chemical indicators, electronic sensors and dialing hygrometers.
The simplest and most commonly used type of humidity indicator is the chemical humidity indicator. These use specific chemicals to change color when moisture is exposed. Cobalt chloride and copper chloride change color because they are exposed to a growing amount of air humidity; Cobalt chloride changes from blue to pink and copper variety from yellow to blue. Although these types of moisture indicator are not as sophisticated or accurate as other types, they can provide a good hint of a general level of moisture.
Chemical moisture indicators are often presented in chemical humidity of paper strips with several circular areas of impregnated chemicals sensitive to Hungalost. Every chemical "place" is formulated so that the color at a particular level of moisture; One card can provide a relatively good hint of a series of humidity levels. These chemical indicators are often integrated into small inserts that have a plastic tracking window. When installing on the side of the shipping container, an electronic equipment cover, or any closed package, they allow rapid visual display of moisture level inside the container. The same type of chemical indicators is also mounted on the compressed air guidance in applications, where there is a critical control of the water content in the air stream.types of moisture indicators of electronic and dial types are able to return more accurate humidity values in applications where accurate humidity content is required. Electronic types usually consist of a long -distance sensor and a digital deducted station, and are often used as a large centralized environmental inspection systems. Dial variants usually have two stuPES, which indicate both the level of moisture and temperature.
