The chamber also features a large viewing window, made of tempered glass with anti-fog and anti-scratch properties, allowing for clear visual inspection of the testing process.
• Precision Temperature and Humidity Control Systems
  • Temperature Control: Capable of maintaining a wide temperature range, typically from -40°C to +100°C, with an outstanding accuracy of ±0.3°C. It utilizes advanced refrigeration and heating technologies, such as cascade refrigeration for extreme low-temperature applications and high-efficiency heating elements for rapid temperature elevation. The control system incorporates a sophisticated feedback loop, with multiple temperature sensors strategically placed throughout the chamber, ensuring uniform temperature distribution and minimal temperature gradients. The user-friendly control panel permits precise programming of temperature profiles, including ramp rates, dwell times, and cycling sequences, enabling the replication of complex real-world temperature variations.
  • Humidity Control: The humidity control system is equally precise, capable of achieving humidity levels from 10% to 95% RH (Relative Humidity), with an accuracy of ±2% RH. It employs a combination of steam humidifiers and dehumidifiers, along with a carefully designed air circulation system. The chamber is equipped with humidity sensors that continuously monitor the internal humidity, and the control system adjusts the humidification or dehumidification processes accordingly. This allows for the creation of stable and dynamic humidity environments, mimicking the diverse moisture conditions that automotive components may face. The system also includes a condensate removal mechanism to prevent any water accumulation within the chamber, safeguarding the tested samples and the chamber's internal components.
• Advanced Instrumentation and Data Acquisition
  • The chamber is outfitted with a comprehensive suite of sensors and instrumentation. In addition to temperature and humidity sensors, it may include pressure sensors to monitor any pressure changes that could affect the test results or the performance of the samples. Light sensors can be incorporated to assess the impact of light exposure in combination with temperature and humidity. These sensors are connected to a state-of-the-art data acquisition system that records and stores all the relevant data. The data acquisition system offers a high sampling rate, typically ranging from 50 to 500 samples per second, ensuring that even the most rapid changes in temperature, humidity, or other parameters are accurately captured. The collected data can be accessed and analyzed in real-time or retrieved later for in-depth studies. The system is also compatible with various automotive-specific data analysis software and can generate detailed reports and graphs, facilitating the interpretation and communication of test results.
• Compliance with DIN 75220 and Safety Features
  • The Customized Temperature Humidity Test Chamber is designed and manufactured to meet the specific requirements of the DIN 75220 standard. It incorporates multiple safety features to protect both the operators and the tested samples. The chamber is equipped with an automatic over-temperature and over-humidity protection system, which shuts down the chamber or activates emergency cooling and dehumidification processes if the set limits are exceeded. It also has a power failure recovery function, which allows the chamber to resume the test operation automatically once the power is restored, ensuring the integrity of the test sequence. The interior lighting is designed to be explosion-proof and suitable for use in a humid environment. The chamber is also equipped with a fire suppression system, which can quickly extinguish any potential fires that may occur during the test. Additionally, the control panel includes built-in alarms and indicators, which alert the operator in case of any abnormal conditions or system malfunctions.

3. Specific Parameters

The specific size can be customized according to the customer's requirements, accommodating different sample sizes and quantities. The interior dimensions are carefully designed to ensure proper air circulation and uniform temperature and humidity distribution. For example, a small chamber may have internal dimensions of 2 feet x 2 feet x 2 feet, suitable for testing small electronic components or individual samples, while a large chamber could have dimensions of 10 feet x 10 feet x 8 feet, capable of testing larger assemblies or multiple samples simultaneously.
• Temperature Uniformity: The temperature uniformity within the chamber is maintained within ±0.5°C, ensuring that all parts of the tested samples experience a consistent temperature environment. This is crucial for obtaining accurate and reliable test results, especially when testing products that are sensitive to temperature variations.
• Humidity Uniformity: The humidity uniformity is maintained within ±3% RH, guaranteeing that the samples are exposed to a uniform humidity level throughout the chamber. This is essential for testing products that may be affected by moisture, such as leather upholstery or paper-based labels.
• Data Acquisition Rate: The data acquisition system can sample sensor data at a rate of 100 samples per second, ensuring that any rapid changes in temperature, humidity, or other parameters are captured and recorded. This high sampling rate allows for detailed analysis of the product's behavior under different environmental conditions.
• DIN 75220 Standard Compliance: The chamber complies with all the relevant clauses and procedures of the DIN 75220 standard, including the specific temperature and humidity profiles, test durations, and sample preparation methods. This ensures that the testing is conducted in a consistent and recognized manner, facilitating market access and compliance with regulatory requirements.

4. Product Functions

• Accurate Simulation of Automotive Environmental Conditions
  • The primary function of this test chamber is to provide a highly accurate and realistic simulation of the temperature and humidity conditions that automotive components will face.
