Humidity Environmental Test Chambers

The design and application of humidity environmental test chamber strictly follow a series of international and national standards, such as GB/T 2423, GJB150A1/4 and so on. These standards specify in detail the reliability, stability and other parameter test requirements of different products in various humidity environments. Taking electronic and electrical products as an example, according to the standard, it is necessary to simulate the environment of high temperature and high humidity, low temperature and high humidity, and detect whether the product will have short circuit, corrosion, performance decline and other problems under the influence of humidity, so as to evaluate the applicability and durability of the product in different actual use scenarios.

Humidity control range: It can simulate from extremely dry environment with low relative humidity of 10% to high humidity environment with high relative humidity of up to 98%, covering the humidity range that may be faced in various natural and industrial production from deserts to tropical rainforests, and can meet the diversified needs of different industries for humidity conditions. ​
Humidity control accuracy: humidity fluctuation range can be accurately controlled within ±2%. For example, in a moisture-proof test for high-precision optical lenses, the humidity is required to be stable at 55% relative humidity. Common equipment can cause large fluctuations in humidity of 50%-60%, which can cause fog on the surface of the lens and affect the accuracy of the optical performance test. The humidity environment test chamber can stably maintain the humidity at 53%-57%, providing a stable and reliable environment for the moisture-proof performance test of the lens, ensuring the accuracy of the test data, and helping enterprises to improve product quality and research and development efficiency. ​

Box structure: box using CNC machine tool processing molding, beautiful shape and durable. The liner is made of imported high-grade stainless steel (SUS304) mirror plate, which not only has strong corrosion resistance, but also is easy to clean to ensure that the test environment is not polluted. The outer bladder is sprayed by A3 steel plate, which increases the appearance texture and cleanliness of the product. The water tank is placed in the lower right part of the control box, and has the function of automatic protection of water shortage, which is convenient for users to replenish the water source in time and ensure the continuous test. ​

Operation interface: Equipped with intuitive and easy to understand operation panel, as the operation of common smart home appliances as convenient. The user simply enters the desired humidity value on the panel and presses the start key, and the test chamber will quickly adjust the internal humidity to the set value. At the same time, the operation interface displays the humidity in the box in real time, which is convenient for users to grasp the test environment status at any time, so that the operation process is more secure and efficient. ​

Safety protection function: with multiple safety protection devices. Such as the test sample protection function, in line with EN60519-21993 thermal safety level 2 standards; It is equipped with an independent and adjustable temperature limiter, which can set the minimum and maximum temperature respectively to ensure that the test sample is carried out humidity test within the appropriate temperature range; The safety temperature limiter (STB) is equipped with test chamber overtemperature protection, in accordance with EN60519-2,1993 Class 1, to ensure safe and reliable operation of the equipment, and to avoid damage to the test sample and the equipment itself due to abnormal conditions. ​
Humidification and dehumidification system: the humidification adopts the surface escape mode, which adds water molecules to the air, and the humidification area is large and the release is smooth, which can effectively ensure the humidity fluctuation is small and the distribution is uniform. Compared with ultrasonic or steam humidification methods, it avoids the problems of small humidification surface, large impact, large humidity fluctuation and uneven distribution caused by adding small water droplets. The dehumidification system uses the evaporator coil dew point temperature laminar flow contact technology to efficiently remove excess water in the box and ensure the accuracy and stability of humidity control.
