Technical principle of constant temperature and humidity testing machine

 constant temperature and humidity testing machine, also known as "programmable constant temperature and humidity test box fr-1204 constant temperature and humidity test box", belongs to the same series as "high and low temperature alternating humidity and heat test box / gds-100". It is a necessary test equipment in aviation, automobile, household appliances, scientific research and other fields. It is used to test and determine the temperature loop of electrical, electronic and other products and materials for high temperature, low temperature, alternating humidity and heat or constant test Parameters and performance after environmental change.

 constant temperature and humidity testing machine is to use a certain way to adjust the temperature and humidity in the box to a given value, and carry out experiments under this condition, in order to meet the requirements of experimental reaction. That is, the test chamber which can simultaneously apply temperature and humidity stress. In short, it means that the temperature and humidity are controlled within the specified range of the test chamber. This chapter is about how the  constant temperature and humidity testing machine is heated, cooled, humidified and dehumidified.
