Stacked double-layer high and low temperature test chamber

Stacked double-layer high and low temperature test chamberAlso known as programmable temperature and humidity test chamber, constant temperature and humidity testing machine, constant temperature and humidity test chamber, constant temperature machine or constant temperature and humidity chamber belong to the same series as "high and low temperature alternating humidity and heat test chamber". Used to simulate the operation of test products in high, low, and humid environments, in order to evaluate the performance of electronic and electrical components, plastics, hardware, chemical industries, such as electronic parts, automotive parts, laptops, and other products.

1、 Product features:

1. Low cost: The enclosure shares one shell and one refrigeration system, so the cost is relatively low;

2. High precision control: The commonly used control system and sensors can accurately control temperature and humidity, ensuring the accuracy and reliability of test results;

3. Flexible customization: The size of the upper and lower constant temperature and humidity test chambers can be customized according to customer needs. The size is relatively flexible, and the lower layer can be smaller or larger than the upper layer;

4. Space saving: The double-layer design can save laboratory space, and its double-layer/three-layer space can also be independently controlled, suitable for products with small size, large quantity, and batch testing;

5. Independent temperature control: Each layer of independent control system can independently control the temperature. A two-layer constant temperature and humidity test chamber is equivalent to having two ordinary constant temperature and humidity test chambers, which can meet the temperature testing requirements of different temperature ranges for test samples in different testing stages.

2、 Structural features:

1. Intelligent control: 7-inch touch screen, supporting program jumping, hot and cold start, and 6-month power-off memory;

2. Monitoring system: Built in 6-point thermocouple for real-time monitoring of uniformity, external video monitoring for testing process;

3. Box design: Stainless steel liner+spray coated steel plate shell, double-layer anti fog window with lighting for easy observation.

3、 Application areas:

1. Research and medicine: drug stability testing, new material aging research, etc;

3. Automotive and Aerospace: Verify the tolerance of engine components and aerospace materials to harsh temperature and humidity environments;

4. Electronic products: Test the reliability of mobile phones and circuit boards under wet and hot cycles (compliant with IEC/GB standards).

4、 Execution and compliance with standards and testing methods:

1. GB2423.1-2016 Basic Environmental Testing Procedures for Electrical and Electronic Products - Test A: Low Temperature Test Method;

2. GB2423.2-2008 Basic Environmental Testing Procedures for Electrical and Electronic Products - Test B: High Temperature Test Method;

3. GB2423.3-2016 Basic Environmental Testing Procedures for Electrical and Electronic Products - Test C: Constant Damp Heat Test Method;

4. GB2423.4-2016 Basic Environmental Testing Procedures for Electrical and Electronic Products - Test D: Temperature Cycle Test Method

5Stacked double-layer high and low temperature test chamberHeating and humidification system:
