Why is humidity testing important for different industries?

Humidity plays a very important role in initiating corrosion on metal surfaces. Continuous exposure to moisture can lead to corrosion, whether the surface is coated or not. A faucet is a very common example of this. Humidity in the bathing area is relatively high compared to other rooms. Therefore, the faucet has a lower electrical resistance compared to other metal parts in the house. In order for a metal item to withstand different working conditions, it is tested under controlled humidity and temperature.

By controlling the temperature of the Humidity Chamber, the desired humidity can be achieved. It is worth noting that the humidity is not easy to control, but the temperature can be controlled. Depending on the temperature of the chamber, humidity will naturally be reached. The chamber has a water storage tank that provides a constant water supply.

The chamber has a heater to increase the temperature and a nebulizer to convert the water into mist or moist air. In this room, a humidity of up to 98% can be achieved. You can't control humidity, but you can definitely measure it. To increase or decrease the humid effect, control the temperature. You just need to pre-set the temperature and place the test sample on the perforated rack. There is a double door protection to avoid any heat loss. Equipped with a glass door to peek inside.

The importance of constant temperature and Humidity Chambers in different industries

In the automotive industry, many components are used that are directly affected by moist air, such as metals, plastics, paints, rubber, etc. Auto parts manufacturers need to have constant temperature and Humidity Chambers in their factories to evaluate the shelf life of their products. However, assembly plants don't need them.

In humid environments, the drying rate of the paint will be significantly increased. If the pigment is supplied in an area with high humidity, instructions for use will need to be issued at the same time. Applicators follow instructions to take proper precautions so as not to damage the coating.

Rubber exhibits volatility under different environmental conditions. Humidity affects different properties of rubber, such as tensile and compressive strength. This is why suppliers of natural or synthetic rubber ensure that samples are tested before being supplied.

Paper loses its ability to resist compression when wet or stays still in wet conditions. The efficacy of paper and subsequent products needs to be tested in a humid humidity Test Chamber to correctly estimate how paper behaves at high humidity.
