1. Product Name and Purpose

2. Product Features

Precise Climatic Control

• Wide Temperature Range
  • The chamber is capable of achieving a broad temperature range, typically from - 70°C to + 150°C. This range is essential as automotive components can be exposed to extremely cold temperatures in winter or high heat in summer, especially in regions with harsh climates. For ECUs, low temperatures can affect the performance of electronic circuits and the functionality of sensors, while high temperatures can cause overheating and potential component failure. Headlight covers may also face challenges such as cracking in cold temperatures or warping in high heat. The precise temperature control, with an accuracy of ±0.5°C, ensures that the components are tested under exacting conditions.
• Accurate Humidity Regulation
  • Humidity levels within the chamber can be precisely regulated from 10% to 95% relative humidity. High humidity can lead to condensation inside ECUs, which may cause short - circuits and damage to electronic components. For headlight covers, humidity can affect the clarity of the cover due to fogging and can also contribute to the corrosion of the underlying headlight components. The humidity control accuracy of ±3% relative humidity ensures that the test environment closely replicates real - world humidity conditions.

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. Advanced air circulation systems and carefully placed sensors work together to ensure that the temperature variation within the chamber is typically within ±1°C, and the humidity variation is within ±5% relative humidity. This uniformity is crucial for accurate testing, as it ensures that all parts of the ECU and headlight covers are exposed to the same environmental conditions, eliminating any potential biases in the test results.
• Long - Term Stability
  • The chamber can maintain stable climatic conditions over extended periods. This is essential for conducting long - term endurance tests on ECUs and headlight covers. For example, an ECU may need to be tested for thousands of hours under specific temperature and humidity conditions to evaluate its long - term reliability. The chamber's ability to maintain stable conditions ensures that the test results are consistent and reliable, allowing manufacturers to make informed decisions about product design and quality.

Multiple Test Modes and Customization

• Programmable Test Profiles
  • Operators have the flexibility to create programmable test profiles that simulate the complex and variable environmental conditions that ECUs and headlight covers encounter in real - world driving scenarios. These profiles can include cyclic temperature and humidity changes to mimic seasonal variations, as well as sudden changes to simulate extreme weather events. For example, a test profile can be designed to simulate the rapid temperature change that an ECU may experience when a vehicle moves from a cold garage to a hot outdoor environment.
  • The ability to create customized test profiles allows manufacturers to test their components under specific conditions relevant to their intended use. This provides more accurate and meaningful test results, enabling them to optimize the design and performance of their products.
• Optional Test Accessories
  • The constant climatic test chamber can be equipped with a variety of optional test accessories to meet specific testing requirements. For ECUs, additional power supplies can be used to simulate different electrical loads, while data acquisition systems can monitor and record the ECU's performance parameters during the test. For headlight covers, lighting fixtures can be installed to test the cover's light transmission and durability under different lighting conditions. Vibration tables can also be added to simulate the mechanical vibrations that these components experience while driving.

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 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 user - friendly design ensures that even operators with limited technical expertise can efficiently conduct tests.
• Remote Monitoring and Control
  • Many models of the constant climatic test chamber offer remote monitoring and control capabilities. This feature is highly beneficial for automotive manufacturers, as it allows them to monitor the test progress and adjust the test parameters from a remote location, such as an office or a quality control center. This is especially useful for long - term tests or when multiple tests are being conducted simultaneously. Remote monitoring and control enable timely intervention in case of any issues, ensuring the smooth and efficient operation of the testing process.
