Precise Climatic Control

• Wide Temperature Range
  • The chamber is capable of achieving a broad temperature range suitable for food and packaging testing. It typically ranges from 0°C to 60°C, which covers the common temperature conditions during food storage, transportation, and display. For example, refrigerated foods can be tested at low temperatures around 0 - 10°C, while products stored at room temperature can be evaluated at 20 - 30°C, and those in warm storage or during transportation in hot climates can be tested at higher temperatures up to 60°C. The temperature control is highly precise, with an accuracy of ±0.5°C. This precision ensures that the test conditions closely match the intended temperature requirements for accurate product evaluation.
• Accurate Humidity Regulation
  • Humidity levels within the chamber can be precisely regulated from 10% to 95% relative humidity. Different food products have different moisture requirements, and excessive or insufficient humidity can lead to spoilage, mold growth, or drying out. For example, high - moisture foods like fresh produce may require higher humidity levels to prevent dehydration, while dry foods like cereals need low humidity to avoid clumping and spoilage. The humidity control accuracy is within ±3% relative humidity, ensuring that the test environment closely mimics the real - world humidity conditions that food and packaging products may encounter.

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 multiple sensors are strategically placed 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 samples of food and packaging products are exposed to the same environmental conditions, eliminating any biases in the test results.
• Long - Term Stability
  • The chamber is capable of maintaining stable climatic conditions over long periods. This is essential for conducting long - term shelf - life tests on food products, which may require continuous exposure to specific temperature and humidity conditions for weeks, months, or even years. The chamber's stability ensures that the test conditions remain constant throughout the test, providing reliable and comparable results for accurate assessment of product shelf - life and quality degradation.

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 food and packaging products experience during their lifecycle. These profiles can include cyclic changes in temperature and humidity to mimic seasonal variations, sudden changes to simulate extreme weather events during transportation, or custom - tailored profiles based on specific product requirements. For example, a test profile can be designed to simulate the temperature and humidity changes that a packaged snack may experience during a long - distance truck journey from a cool warehouse to a hot retail store.
  • The ability to create customized test profiles allows manufacturers to test their products under conditions that are highly relevant to their actual storage and distribution scenarios. This provides more accurate and meaningful test results, enabling them to make informed decisions about product packaging, storage conditions, and shelf - life extension strategies.
• Optional Test Accessories
  • The constant climatic test chamber can be equipped with a variety of optional test accessories to meet specific testing requirements. For food products, sensors can be added to monitor parameters such as moisture content, pH levels, and gas composition within the packaging. For packaging materials, instruments can be integrated to test properties like oxygen permeability, water vapor transmission rate, and mechanical strength. Additionally, lighting systems can be installed to simulate the effects of light exposure on food and packaging, as light can also contribute to product degradation.

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 on food and packaging products.
• Remote Monitoring and Control
  • Many models of the constant climatic test chamber offer remote monitoring and control capabilities. This feature is highly beneficial for food 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 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.
