Metal that has not been coated is prone to corrosion. And the most common reason of corrosion is humidity in the air. More the moisture content in the air, the more protection is required for metal. This is why there arises a need to create an instrument, called humidity tester or humidity chamber. Humidity Chamber could easily simulate the weathering conditions and adjudge the response of metal to that conditions.
How humidity chamber works?
Humidity chamber can create environmental conditions with controlled temperature and humidity. The chambers are equipped with heaters and fans. As soon as heater raises the temperature, the fans distribute the heat uniformly throughout the chamber. Uniform heat distribution is very important so as to avoid any discrepancy in the result.
For generating a humid air, there is a placement of automizer. This automizer can be easily related to spray nozzle to control the water spray. Due to high temperature in the chamber, the sprayed water tends to moist the air. Humidity from 65% to 98% can be easily achieved. As the temperature of heater decreases, the percentage of humidity also decreases. One important point to consider, humidity cannot be controlled but can be checked with a tester.
What are major industries that need a humidity chamber?
Any product whose raw material gets affected by humidity needs this testing instrument. To name a few;
