The Bench-top temperature and humidity test chamber is widely used in scientific research, research institutes, quality inspection institutes and other industries to do warm and humid heat tests of electronic and electrical products, materials, parts, equipment, etc.

Application fields of The Test Chamber

The bench-top temperature humidity test chamber is a device used to simulate environmental tests under different temperature and humidity conditions. It is widely used in aviation, aerospace, information, electronics, instrumentation, automobiles, home appliances, scientific research and other fields. As follows:

• Electronic product testing: used to test the temperature and humidity resistance of electronic components and equipment.
• Material research: suitable for the performance research of materials such as plastics, metals, and coatings.
• Biological experiments: control the growth environment in biopharmaceuticals and microbiological research.
• Quality testing: used for quality control of various products to ensure their safety and reliability under specific environmental conditions.

The application of bench-top type constant temperature and humidity test chambers in these fields not only improves the quality and reliability of products, but also promotes the development of scientific research and technological innovation.

The Test Standards Of The test Chamber

The bench-top Temperature humidity test chamber can accurately control temperature and humidity and provide stable environmental conditions. At the same time, it can also simulate some extreme environments, such as high temperature, low temperature, high humidity and low humidity, to test the durability and reliability of the product. , The following are some common standards and specifications for desktop constant temperature and humidity test chambers:

• IEC 60068-2-1 "Environmental testing Part 2: Test methods Test A: Low temperature": specifies the methods and requirements for low temperature tests.
• ISO 16750: International Organization for Standardization (ISO) standard for automotive electronic equipment, which includes test requirements for environmental conditions.

• MIL-STD-810: A military standard developed by the U.S. Department of Defense that covers a variety of environmental testing methods, including high temperature and high humidity testing.

The Bench-top temperature humidity test chambers also also complies with test standards such as JIS Z 0202, ANSI/TIA/EIA 455-162, MIL-STD-810, ASTM D 2247, BS EN 61300-2-48, etc.

Control System Of Small Test Chambers

The controller system of Sanwood test chamber adopts world leading hardware and software systems to ensure that the test box operates under preset conditions, providing accurate and reliable experimental data to help users achieve precise control and data collection of various experimental conditions.

• Controller: The TEMI 1500 controller imported from Sanwontech in South Korea and the self-developed Siemens control system are used, equipped with RS232, RS485, and Ethernet communication ports. 
• Programmable control: supports setting experimental programs, such as heating, cooling, holding time, etc., and executing multiple program settings.Support advance reservation for power on function.
• Multiple languages optional: English, Korean, Russian, Chinese, and Japanese.
• Precise control: able to accurately set and maintain specific temperature ranges and humidity levels, accurately simulate various environments.
• Remote monitoring: Using SAMWON-EZNET network remote technology to achieve remote control, the test chamber can be monitored at any time and emails can be sent to users' PCs and phones, enhancing convenience.

The specific control system of the test chamber may vary depending on the model, so it is necessary to carefully read the Sanwood Environmental Test Chamber Manual and follow safety operating procedures before use.

Refrigeration System Of Small Test Chamber

The refrigeration system of the test chamber is a complex and important system, and the quality of the refrigeration system is crucial for the accuracy and reliability of the test results.

• Sanwood has developed hot air refrigerant defrosting technology, which effectively melts the frost on the evaporator by injecting high-temperature and high-pressure refrigerant vapor into the heat exchanger inside the test chamber. This not only ensures that the evaporator does not frost, but also greatly reduces the energy consumption of the equipment.
• The refrigeration unit adopts international famous brands and cooperates with Japan's Eginomiya and the US Sporan to develop EPV series and XUP series quick opening solenoid valves for energy-saving systems, with an all-weather service life of over 15 years. And began to develop the new Danfoss AKV series throttling electronic expansion valve system, which is more efficient and energy-saving.
• Optimizing the layout of the refrigeration system adopts VRF (refrigerant flow control) technology based on PID cold end output principle to achieve low-temperature energy-saving operation, which can reduce energy consumption by 30% under low-temperature conditions.
• The refrigeration system adopts modular design, achieving low failure rate,less welding joints, high refrigeration efficiency, good reliability, simple maintenance, and low repair costs.
