2. Product Features

Temperature and Humidity Test Chamber

• Wide Temperature and Humidity Range
  • The temperature control in this system can achieve an extensive range, typically from - 40°C to + 85°C. This wide spectrum allows for the simulation of various climate conditions, from the freezing cold of polar regions to the sweltering heat of deserts. The humidity control can maintain relative humidity levels from 10% to 95%. This enables the testing of how communication devices respond to different moisture levels, which is critical for preventing issues like corrosion of electronic components, short - circuits, and degradation of signal quality.
  • The temperature and humidity control is highly precise, with an accuracy of ±0.5°C for temperature and ±3% for humidity. This level of precision ensures that the test conditions closely mimic the actual environmental conditions that communication devices may encounter, providing reliable and consistent test results.
• Rapid Temperature and Humidity Transitions
  • The system is capable of rapid temperature and humidity transitions, essential for simulating sudden changes in the environment. For example, when a communication device is moved from an air - conditioned indoor environment to a hot and humid outdoor area. The system can achieve temperature transition rates of up to 5°C/min and humidity transition rates of up to 5%/min. This allows for the testing of how devices respond to these abrupt changes, helping to identify potential failures due to thermal stress or moisture absorption.
• Uniformity within the Chamber
  • The test chamber is designed to provide excellent temperature and humidity uniformity. The temperature variation within the chamber is typically within ±1°C, and the humidity variation is within ±5% relative humidity. This ensures that all devices being tested are exposed to the same environmental conditions, eliminating any potential biases in the test results.

Vibration Test Section

• Multi - Axis Vibration Capability
  • The vibration test section of the system can generate vibrations in multiple axes, including vertical, horizontal, and lateral directions. Communication devices are often subjected to complex vibration patterns during normal use, such as being dropped, shaken, or carried in a moving vehicle. Testing in multiple axes helps to uncover potential failure modes that may not be detected with single - axis testing.
  • The vibration frequencies can be precisely controlled, ranging from a low 1 Hz to a high 2000 Hz. This wide frequency range allows for the simulation of different types of vibrations, from the low - frequency vibrations during transportation to the high - frequency vibrations caused by sudden impacts. The vibration amplitudes are adjustable, enabling the reproduction of various levels of intensity, from minor vibrations to severe shocks.
• Customizable Vibration Profiles
