Why is Humidity Testing Important for Different Industries?

Humidity plays a very important role in initiating the corrosion on metal surfaces. Whether the surface is coated or uncoated, constant exposure to humidity would lead to corrosion. Faucets are very common example of this. In comparison to other rooms, humidity in the bathing area is relatively high. Thus, faucets have low resistance in comparison to other metal components in the house. To make metal things withstand different working conditions, it is tested in controlled humidity and temperature.

Standard Operating Procedure

By controlling the temperature of the humidity test chamber, desired humidity can be achieved. It is a noteworthy point that it is not easy to control the humidity, you can control the temperature. Based on the temperature of the chamber, humidity gets achieved naturally. There is a water reservoir tank with the chamber, that gives a constant water supply.

The chamber has a heater to raise the temperature and an atomiser to convert water into fog or humid air. In this chamber, up to 98% of humidity can be achieved. You cannot control the humidity but definitely, can measure it. To increase or decrease the humid effect, the temperature is controlled. You just need to pre-set the temperature and place the test sample on the perforated shelves. There is a double door protection to avoid any heat loss. Equipped with a glass door to peep inside the chamber.

Importance of humidity chamber in different industries.

  • In the automotive industry, there are many components used which directly gets affected by humid air, like, metal, plastic, paint, rubber, etc. Automotive parts manufacturers must have to have humidity chamber in their plants to assess the shelf life of their products. However, assembling plants don’t need them.
  • The drying rate of paints increases considerably in a humid If the pigments are supplied in the region where humidity is quite high, the application instructions need to be released along. Appropriate precautions are taken by the applicator in according with the instruction, so as not to spoil the final coating.
  • Rubber shows volatile behaviour when subjected to different environmental conditions. Humidity affects the different properties of the rubber like tensile and compressive strength. This is why natural or synthetic rubber suppliers make sure that sample is tested prior supplying.
  • Paper loses its resistance against pressure when moist or remain to rest in humid conditions. The paper and its subsequent products need to be tested for their efficacy in a humid Humidity test chamber gives the right estimation about the behaviour of paper in high humidity.
