The principle of changing the content of water molecules to measure air humidity; the dry and wet bulb hygrometer is based on the principle of evaporation, using two field parameters of ambient temperature and wet bulb temperature to determine the air humidity), simulating the dehumidification and humidifier of the cooling element in the laboratory with Bolt paste Humidify, configure a fan to ensure that the air is fully mixed. The core part of the experiment platform is to simulate the humidity changes in the atmosphere with electrical components that can humidify and dehumidify, through the hair hygrometer Four different hygrometers such as, capacitive hygrometer and dry and wet bulb hygrometer respectively measure the humidity changes in the simulated laboratory (fiber hygrometer is based on fiber characteristics to measure air humidity; capacitive hygrometer is based on the conductivity of the environment. Through the designed related experiments, students can be familiar with the working principle of the basic hygrometer and cultivate the corresponding knowledge and skills and the ability of innovation and development. The Basic humidity measurement experiment platform is a training and teaching device used by the laboratory to compare and learn several basic humidity measurement principles.

Features:

The test bench is equipped with a fan to ensure that the air is fully mixed.

There are four hygrometers with different principles on the experimental bench.

The test bench is equipped with a simulation laboratory that simulates the change of atmospheric humidity, and uses a Bolt cooling element and a humidifier to quantitatively adjust the environmental humidity.

In order to facilitate observation, the simulation laboratory is equipped with a fully transparent observation window to clearly reflect the process changes.
