Constant Climate Control Chamber Test For Reliability Test Of Mobile Phones Computers Tablets

1. Product Name and Purpose

2. Product Features

Precise Climatic Control

• Wide Temperature Range
  • The chamber is capable of maintaining a temperature range that is highly relevant to the testing needs of mobile phones, computers, and tablets. It can reach extremely low temperatures, typically as low as - 70°C, which is useful for testing how these devices perform in cold climates, such as during winter outdoor use or in cold storage facilities. On the other hand, it can also achieve high temperatures of up to + 150°C, simulating the heat that these devices may experience in hot environments, like in a car parked under the sun or in a poorly ventilated room with high ambient temperatures.
  • The temperature control is highly precise, with an accuracy of typically ±0.5°C. This level of precision ensures that the devices are exposed to the exact temperature conditions required for the test, enabling accurate and reliable assessment of their performance.
• Accurate Humidity Regulation
  • Humidity levels within the chamber can be precisely regulated from as low as 10% relative humidity to as high as 95% relative humidity. This wide range is crucial as mobile phones, computers, and tablets are used in various humidity conditions. Low humidity can cause static electricity problems, while high humidity can lead to corrosion, short - circuits, and other electrical issues.
  • The humidity control accuracy is usually within ±3% relative humidity. This ensures that the test environment closely replicates the real - world humidity conditions that these devices may encounter, providing reliable test results.

Stable and Uniform Environment

• Uniform Climatic Distribution
  • The interior of the constant climatic test chamber is designed to provide a uniform distribution of temperature and humidity throughout the test volume. This is achieved through a combination of advanced air circulation systems and precise sensor placement. The temperature variation within the chamber is typically within ±1°C, and the humidity variation is within ±5% relative humidity.
  • For mobile phones, computers, and tablets, which are often small in size but contain many sensitive components, a uniform environment is crucial. It ensures that all parts of the device are exposed to the same climatic conditions, eliminating any bias in the test results and providing a more accurate representation of the device's performance under real - world conditions.
• Long - Term Stability
  • The chamber is capable of maintaining stable climatic conditions over long periods of time. This is essential for conducting endurance tests on mobile phones, computers, and tablets. For example, a long - term test may involve exposing a device to a specific temperature and humidity combination for several days or even weeks to evaluate its long - term performance and reliability. The chamber's stability ensures that the test conditions remain constant throughout the test, allowing for consistent and comparable results.

Multiple Test Modes and Customization

• Programmable Test Profiles
  • Operators have the flexibility to create programmable test profiles that can simulate the complex and diverse environmental conditions that mobile phones, computers, and tablets may encounter in real life. These profiles can include cyclic changes in temperature and humidity to mimic seasonal variations or sudden changes to simulate extreme weather events. For example, a test profile can be designed to simulate the temperature and humidity changes that a mobile phone may experience during a day at the beach, with high humidity in the morning, increasing temperature during the day, and a sudden drop in temperature and humidity in the evening.
  • The ability to create customized test profiles allows manufacturers to test their devices under specific conditions that are relevant to their intended use. This provides more accurate and meaningful test results, enabling them to better understand how their products will perform in different real - world scenarios.
• Optional Test Accessories
  • The constant climatic test chamber can be equipped with a variety of optional test accessories to meet specific testing requirements of mobile phones, computers, and tablets. These accessories can include power supplies, data acquisition systems, and vibration tables. For example, a vibration table can be added to the chamber to simulate the mechanical vibrations that these devices may experience during transportation or normal use. A data acquisition system can be used to monitor and record the performance of the devices during the test, such as battery life, processing speed, and display quality.

User - Friendly Operation and Monitoring

• Intuitive Control Interface
  • The chamber is equipped with an intuitive control interface that simplifies the operation process. The interface allows operators to easily set and adjust the test parameters, such as temperature, humidity, test duration, and test profiles. It also provides a clear display of the current test status, including the actual temperature and humidity values, elapsed test time, and any error messages.
  • The control interface is designed to be user - friendly, even for operators with limited technical expertise. This ensures that the testing process is efficient and accurate, allowing for quick and easy setup of tests for mobile phones, computers, and tablets.
• Remote Monitoring and Control
  • Many models of the constant climatic test chamber offer remote monitoring and control capabilities. This feature is particularly useful for manufacturers and quality control teams, as it allows them to monitor the test progress and adjust the test parameters from a remote location, such as an office or a control center. This is especially beneficial for long - term tests or when multiple tests are being conducted simultaneously.
  • Remote monitoring and control also enable operators to respond quickly to any issues or changes that may occur during the test, ensuring the smooth and efficient operation of the testing process.
