Customized Temperature Humidity Impact Test Machine for Environmental Stress Testing

1. Product Name and Purpose

2. Product Features

• Robust and Insulated Chamber Structure
  • The test machine is constructed with a heavy-duty stainless steel frame and high-quality insulation materials. The stainless steel frame provides exceptional strength and durability, ensuring the machine can withstand the rigors of continuous testing. The insulation is designed to minimize heat transfer between the interior and exterior of the chamber, allowing for precise temperature control and rapid temperature changes. The chamber door is equipped with a reliable sealing mechanism, such as a double-layer silicone gasket, to prevent any leakage of temperature and humidity, maintaining a consistent and accurate test environment.
• Precision Temperature and Humidity Control System
  • The heart of the machine lies in its advanced temperature and humidity control system. It can achieve a wide temperature range, typically from -70°C to +150°C, with an accuracy of ±0.5°C. The humidity control range extends from 10% to 95% relative humidity, with an accuracy of ±3% RH. The system utilizes high-performance refrigeration units, electric heaters, humidifiers, and dehumidifiers, all coordinated by a sophisticated PID controller. Temperature and humidity sensors are strategically placed within the chamber to provide real-time feedback, enabling the control system to make instantaneous and precise adjustments to maintain the desired environmental conditions.
• Rapid Temperature and Humidity Change Capability
  • One of the standout features of this machine is its ability to effect rapid changes in temperature and humidity. It can achieve a temperature change rate of up to 20°C per minute and a humidity change rate of up to 10% RH per minute. This rapid cycling is essential for simulating the abrupt environmental shifts that products may experience, such as when an electronic device is moved from a cold outdoor environment to a warm, humid indoor space. The machine can also perform complex temperature and humidity profiles, including step changes, ramps, and cycling between different setpoints, providing a comprehensive assessment of a product's resilience.
• Intuitive Control Panel and Data Acquisition Interface
  • The equipment is equipped with an intuitive control panel that allows operators to easily program and manage test sequences. The panel provides a user-friendly interface for setting temperature, humidity, test duration, and cycling parameters. It also displays real-time information about the current environmental conditions inside the chamber, as well as any alarms or warnings. The machine is integrated with a comprehensive data acquisition system that records all relevant test data, including temperature and humidity histories, time stamps, and any changes in the physical properties of the test samples. The data can be stored in a built-in memory or exported to external storage devices for further analysis and reporting.
• Versatile Sample Fixturing and Placement
  • The interior of the chamber is designed to accommodate a wide variety 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 made of materials that are resistant to temperature and humidity changes and do not contaminate the test environment. This flexibility allows for the testing of different products, from small electronic components to large automotive parts or pharmaceutical packaging. For example, circuit boards can be mounted on specialized racks to mimic their actual installation conditions, while automotive engines can be placed on custom platforms for comprehensive testing.

3. Specific Parameters

• Maximum Temperature Swing and Accuracy
  • With a temperature range spanning from -70°C to +150°C, the machine can achieve a maximum temperature swing of 220°C. The accuracy of ±0.5°C ensures that the test conditions are precisely maintained, providing reliable and repeatable results. This wide temperature spectrum is crucial for testing products that may be exposed to extreme cold, such as in aerospace applications, or extreme heat, like in automotive engine compartments.
• Humidity Range and Rate of Change Accuracy
  • The humidity range of 10% to 95% RH, with a rate of change accuracy of ±3% RH, allows for a comprehensive evaluation of the effect of moisture on products. The ability to rapidly change humidity levels helps in understanding how products respond to different moisture environments, such as the condensation that may occur when a cold product is exposed to a humid atmosphere. This is particularly relevant for electronics, where moisture can cause short circuits or corrosion.
• Testing Volume and Payload Capacity
  • The machine offers a customizable testing volume, with options ranging from 0.5 m³ to 10 m³. The payload capacity can be adjusted according to the size and weight of the test samples, with a maximum capacity of up to 1000 kg. This allows for the testing of a significant number of samples or larger and heavier products. For example, in the automotive industry, multiple engine components or even complete engines can be tested simultaneously, saving time and resources.
• Temperature and Humidity Cycling Durations
  • The machine can perform cycling tests with durations ranging from a few minutes to several thousand hours. This flexibility enables the simulation of short-term environmental shocks, such as those experienced during transportation, as well as long-term exposure to varying conditions, like the seasonal changes a product might endure in its service life. The ability to precisely control the cycling parameters is essential for accurately assessing a product's durability.
• Data Sampling Frequency and Resolution
  • The data acquisition system samples data at a frequency of up to 100 Hz, providing a detailed record of the temperature and humidity changes. The resolution of the temperature data is 0.1°C, and the humidity data is 0.1% RH, allowing for a fine-grained analysis of the test environment and the product's response. This high-resolution data is invaluable for identifying subtle trends and potential failure points.

4. Product Functions
