A constant temperature and humidity test chamber is a device used to simulate different environmental conditions and conduct environmental adaptability tests on products. The constant temperature and humidity test chamber with customizable humidity variation range has the following characteristics and applications:

Structural characteristics

Box structure: It is usually made of high-quality stainless steel or cold-rolled steel plate, which has good corrosion resistance and strength. The internal design of the box is reasonable, with high space utilization, making it easy to place test samples of different sizes. The inner liner is generally made of stainless steel material, with a smooth surface, easy to clean, and not prone to bacterial growth.

Refrigeration system: using imported compressors and environmentally friendly refrigerants, with high refrigeration efficiency and low energy consumption. The refrigeration system can quickly reduce the temperature inside the box to the set value and maintain a stable low temperature state. At the same time, it is equipped with efficient condensers and evaporators to ensure uniform cooling effect and avoid local temperatures being too low or too high.

Heating system: using nickel chromium alloy electric heater, with fast heating speed and high temperature control accuracy. The heater is distributed inside the box to evenly dissipate heat to all corners, ensuring the uniformity of temperature inside the box. The heating system and cooling system work together to achieve precise control of the temperature inside the box.

Humidification system: The humidification system of the constant temperature and humidity test chamber, which can customize the range of humidity changes, is one of its core components. Generally, shallow groove humidification or steam generator humidification methods are used. Shallow groove humidification is achieved by setting a shallow water tank at the bottom of the box and using an ultrasonic atomizer to atomize the water before sending it into the box, gradually increasing the humidity inside the box. Steam generator humidification is achieved by heating to produce steam, which is then introduced into the box to achieve the purpose of humidification. Both of these humidification methods can achieve rapid changes and precise control of humidity, meeting the testing needs of different humidity ranges.

Control system: Adopting advanced microcomputer control system, with touch screen operation interface, simple and convenient operation. The control system can accurately control parameters such as temperature, humidity, and time inside the box, and can preset multiple sets of programs to achieve automatic cyclic testing. At the same time, it has data recording and storage functions, which can record temperature and humidity data in real time during the testing process, facilitating subsequent analysis and traceability. In addition, it also has protection functions such as over temperature, over humidity, water shortage, overload, etc., to ensure the safety of equipment and samples.

Functional advantages

Wide humidity range: Customizable humidity variation range, able to meet various testing needs from extremely low humidity to extremely high humidity. For some products that require testing in a dry environment, such as electronic components, pharmaceuticals, etc., the humidity can be controlled at a lower level, such as around 10% RH; For some products that require testing in humid environments, such as textiles, rubber products, etc., the humidity can be adjusted to above 90% RH, or even close to saturation humidity.

Fast rate of humidity change: The humidification and dehumidification systems are designed reasonably and can achieve rapid changes in humidity in a short period of time. This is of great significance for simulating some rapidly changing environmental conditions, such as humid environment after heavy rain, dry environment in desert, etc. The rapid rate of humidity change can improve testing efficiency, shorten testing cycles, and save time and costs.

High humidity control accuracy: By using high-precision humidity sensors and advanced control algorithms, humidity can be controlled within a very precise range. The general humidity control accuracy can reach ± 2% RH or higher, ensuring the accuracy and reliability of test results. This is particularly important for some humidity sensitive products, such as precision instruments, optical components, etc., as it can truly reflect the performance changes of the product under different humidity conditions.

Temperature and humidity coordinated control: Temperature and humidity are interrelated environmental factors, and this test chamber can achieve coordinated control of temperature and humidity. Under different temperature conditions, the saturation of humidity will also change. The test chamber can automatically adjust the set humidity value according to the temperature changes, so that the temperature and humidity conditions inside the chamber are always maintained in a state that meets the testing requirements. This collaborative control method is more in line with the changing laws of actual environmental conditions, providing a more accurate simulated environment for product environmental adaptability testing.
