In our life, many products need to undergo rigorous testing, and constant temperature and humidity test chamber is one of the important tools. It can simulate a variety of complex natural environments to test the performance of products.
What is a constant temperature and humidity test chamber?
A constant temperature and humidity test chamber is known by many different names, such as constant temperature and humidity tester, constant temperature and humidity chamber, programmable humidity and heat test chamber, constant temperature machine or constant temperature and humidity chamber. It can precisely control the temperature and humidity to simulate different climatic conditions. Whether it is electronic products, automotive parts, or food, medicine and other fields, you can see its figure.
How does a constant temperature humidity chamber work?
A humidity chamber consists of several systems. It has a cooling system, a heating system, a control system, a humidity system, an air circulation system and a sensor system.
● Temperature control
Constant temperature and humidity test chamber is to control the temperature by heating and cooling.
The heating system usually adopts high-power resistance wire or electric heating element. When the temperature needs to be raised, the controller will send a signal to make the heating element work according to the temperature data fed back from the sensor.
The refrigeration system, on the other hand, through the compressor, condenser and other components, will take away the heat inside the box to achieve cooling.
● Humidity control
The process of humidifying the constant temperature and humidity test chamber is actually to increase the partial pressure of water vapour, using steam humidification type humidification. The equipment is controlled by the controller first, the sensor senses the humidity, and when the actual humidity is lower than the set humidity, the humidification system will be activated.
● Air Circulation System
Through the rotating fan installed at the top of the chamber, air is discharged into the chamber. In this way to achieve gas circulation, balance the temperature and humidity in the box.
How does the constant temperature humidity chamber achieve precise control?
Constant temperature and humidity test chamber is through the heating, cooling, humidification, humidity and other capabilities to achieve precise control.
It has a very advanced control system, like a PLC control system, which can be operated by touch screen or computer software. You can set the desired temperature and humidity.
Secondly, it has good insulation and sealing performance. Insulating materials and seals are used to stop the external environment from affecting the test.
Further, the accurate sensor technology also contributes. The high-precision platinum resistance thermometer has the advantages of high sensitivity, good linearity and stability. Can accurately and quickly perceive the temperature change in the test box.
How does the constant temperature humidity chamber meet different temperature testing needs?
Its temperature range is very wide. Low temperature is generally divided into 0 ℃, -20 ℃, -40 ℃, -70 ℃.
The common high temperature is 85℃, 120℃, 150℃.
This range of temperatures can satisfy most testing needs.
Is Aibo's constant temperature humidity chamber worth getting?
What is so special about the Aibo humidity chamber? It can simulate a wide range of different environmental conditions. Whether it's high or low temperatures, high or low humidity, it can be precisely controlled. This is simply an indispensable tool for industries such as electronic components, plastic products and electrical appliances.
Moreover, we have done an excellent job in quality assurance. We have established a quality assurance management system in strict accordance with the ISO9001:2000 standard. Let you use it with more confidence.
In addition, our constant temperature and humidity test chamber has unique technology in humidification and cooling. Different humidification principles, such as water humidification, can make the wall area increase with water, providing a more stable environment for the test. And in the refrigeration system, even if the evaporation temperature is too low, various factors can be adjusted to ensure the normal operation of the equipment.
If you are struggling to find a reliable constant temperature and humidity tester, consider Aibo.
