408L Temperature Humidity Test Chambers With Refrigerant

1. Product Name and Purpose

2. Product Features

• Sturdy and Insulated Chamber Structure
  • The chamber is constructed with a heavy-duty steel frame that imparts exceptional structural integrity, ensuring its ability to withstand the rigors of continuous and demanding testing cycles. The insulated walls are crafted from high-quality materials that minimize heat transfer and maintain a stable internal environment. The door is equipped with a reliable locking mechanism and a large, tempered glass viewing window, allowing operators to closely monitor the test process without compromising the integrity of the chamber's internal climate. The seals and gaskets are of premium quality, guaranteeing an airtight and watertight enclosure, which is crucial for accurate and consistent test results.
• Precision Temperature and Humidity Control System
  • At the core of this remarkable chamber lies a state-of-the-art temperature and humidity control system. It can achieve the specified temperature range of +150℃ to -70℃ with an astonishing accuracy of ±0.2℃. The humidity control range extends from 10% to 95% relative humidity, with an accuracy of ±1.5% RH. The system incorporates advanced refrigeration units, powerful electric heaters, and highly efficient humidifiers and dehumidifiers, all coordinated by a sophisticated PID controller. Multiple sensors are strategically positioned throughout the chamber to provide real-time feedback, enabling the control system to make instantaneous and precise adjustments to maintain the desired environmental conditions.
• Efficient Air Circulation and Uniformity
  • To ensure uniform temperature and humidity distribution within the 408L volume, an elaborate air circulation system is implemented. High-capacity fans, in conjunction with a carefully designed ductwork, create a turbulent-free airflow that eliminates any hot or cold spots. The adjustable air velocity, typically ranging from 1 m/s to 5 m/s, further enhances the homogeneity of the environment, ensuring that every part of the test sample is exposed to identical conditions. This is of paramount importance for obtaining accurate and reliable test results, especially when dealing with large or complex products.
• Intuitive Control Panel and Data Acquisition Interface
  • The equipment is equipped with an intuitive control panel that simplifies the operation and parameter setting. Operators can effortlessly adjust the temperature, humidity, test duration, and other parameters using a user-friendly interface. The control panel also provides real-time displays of the current test conditions, as well as any alarms or warnings. The chamber is integrated with a comprehensive data acquisition system. It records all relevant test data, including temperature and humidity histories, rate of change of environmental parameters, and any observable changes in the test samples. The data can be stored in a built-in memory or exported to external storage devices for in-depth analysis. The system can also generate detailed test reports in various formats, facilitating easy documentation and sharing of results.
• Versatile Sample Fixturing and Placement
  • The interior of the chamber is designed to accommodate a diverse range of sample sizes and shapes. It can be equipped with adjustable racks, trays, and custom-made holders to ensure proper positioning and exposure of the test samples. The sample fixturing is fabricated from materials that are inert and do not contaminate the test environment. This flexibility allows for the testing of different products, from small electronic chips and connectors to larger assemblies such as automotive engines or aerospace components.
