What is the difference between the humidity of the high and low temperature humidity and heat alternating test chamber and the water placed in water?

High and low temperature humidity and heat alternating test chamber is aviation, automotive, home appliances, scientific research and other fields * test equipment, used to test and determine the electrical, electronic and other products and materials for high temperature, low temperature, alternating humidity heat or constant test temperature environment changes parameters and performance
.

When we just use the high and low temperature humidity and heat alternating test chamber, we will be more prone to many misunderstandings, such as the high and low temperature humidity and heat alternating test chamber that Xiaobian will say next, is it the same as directly putting the product in the water? Let's analyze it
for you.

*First, let's analyze the humidity of
the high and low temperature humidity heat alternating test chamber.

The humidity mentioned here refers to the relative humidity, which means that in a certain environment, the water vapor in the air has reached a saturated state, and the temperature at this time is also called the dew point, and the liquid water in this environment can no longer evaporate
.

It needs to be emphasized here: humidity is the saturation of water vapor in the air, not liquid water
.

From the above definition, we can see that water vapor is an invisible gaseous state, and people can breathe in this environment, but if they are in water, they cannot breathe, because the lungs cannot take oxygen
in the water.

Similarly, fish cannot survive in humidity because they can absorb oxygen from water, but not oxygen
from water vapor.

Water vapor and water are not the same thing, although they are both essentially water, but one is a gas and the other is a liquid
.

Therefore, in summary, the humidity of the high and low temperature humidity and heat alternating test chamber is completely different from that in the water!
