Packaging And Product Temperature Humidity Chamber Meets ISTA Standards

1. Product Name and Purpose

2. Product Features

• Robust and Adjustable Structure
  • The chamber is constructed with a heavy-duty framework, typically made of corrosion-resistant stainless steel or high-strength alloy. This ensures long-term durability and stability, even in harsh testing environments. Its modular design allows for easy customization, accommodating a wide range of product sizes and shapes. The interior is equipped with adjustable shelves and racks, enabling precise positioning of test samples. The door is engineered with a reliable sealing mechanism, incorporating a high-quality gasket and a secure locking system. This guarantees an airtight enclosure, preventing any leakage of conditioned air and maintaining the integrity of the test environment. The chamber also features a large viewing window, made of tempered glass with anti-fog properties, allowing for clear visual inspection of the testing process without disturbing the internal conditions.
• Precision Temperature and Humidity Control Systems
  • Temperature Control: The chamber is outfitted with a highly accurate temperature control system, capable of maintaining a wide temperature spectrum, usually from -40°C to +85°C, with an outstanding accuracy of ±0.5°C. It employs advanced refrigeration and heating technologies, such as cascade refrigeration for extreme cold conditions and high-power heating elements for rapid temperature elevation. The control system utilizes 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, mimicking the complex temperature changes during transit.
  • 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 ±3% RH. It utilizes a combination of steam humidifiers and dehumidifiers, along with a well-designed air circulation system. The chamber is fitted 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, replicating the diverse moisture conditions that products may face, such as humid tropical regions or arid deserts. The system also includes a condensate removal mechanism to prevent any water accumulation within the chamber, safeguarding the tested samples.
• Advanced Instrumentation and Data Acquisition
  • The chamber is equipped 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 integrity of the packaging. 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 20 to 200 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 data analysis software and can generate detailed reports and graphs, facilitating the interpretation and communication of test results.
• Compliance with ISTA Standards and Safety Features
  • The Customization Temperature Humidity Test Chamber is designed and manufactured to meet the relevant ISTA standards, such as ISTA 1A, 2A, 3A, etc., depending on the specific testing requirements. 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

• Chamber Size and Capacity: The test chamber is available in a variety of sizes, with internal volumes ranging from a few cubic feet to several hundred cubic feet. 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 3 feet x 3 feet x 3 feet, suitable for testing small consumer electronics or individual packaging units, while a large chamber could have dimensions of 10 feet x 10 feet x 10 feet, capable of testing palletized loads or large industrial equipment.
• Temperature Uniformity: The temperature uniformity within the chamber is maintained within ±1°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.
