WDW Series Microprocessor Controlled Electronic Universal Testing Machine Environment Box

The WDW Series Microprocessor-Controlled Electronic Universal Testing Machine with Environmental Chamber is a specialized mechanical testing system developed and manufactured by Zhejiang Yiyu Instrument Equipment Co., Ltd. Featuring a compact design and user-friendly operation, the system is primarily designed to provide a precise, controllable high- and low-temperature environment for material tensile, compression, and flexural testing. It supports mechanical property research on metals, non-metals, and composite materials, serving as a vital tool for research institutes and corporate laboratories to evaluate material performance under extreme environmental conditions.

Core Design and Functional Highlights

Advanced Environmental Simulation Technology:

• Wide Temperature Range Control: The chamber simulates temperatures ranging from -40°C to +150°C. 
  
• High Uniformity: Utilizes a centrifugal fan for internal air circulation, ensuring uniform temperature distribution. 
  
• Rapid Temperature Change: Under no-load conditions, the heating rate reaches 1–3°C/min, and the cooling rate is 0.7–1°C/min.

Premium Materials and Durability:

• Mirror-Finish Interior: The inner liner is made of heat-resistant stainless steel with a mirror finish, offering both aesthetic appeal and corrosion resistance. 
  
• Effective Thermal Insulation: Equipped with a thick layer of heat-resistant fiber insulation to minimize heat loss. 
  
• Superior Craftsmanship: The exterior features a high-quality painted finish; the front door includes a glass observation window and an internal lighting system, allowing operators to monitor the testing process in real-time.

Precision Measurement and Control:

• High Resolution Across Full Range: Force resolution reaches 1/±300,000 of the maximum test force and remains constant throughout the entire test. 
  
• Precise Control: Achieves Class 1 accuracy, with the relative error of the indicated test force strictly controlled within ±1%.

Complies with Multiple National Standards:

• The equipment is designed in strict accordance with standards such as GB/T 16491 (Electronic Universal Testing Machines), GB/T 2611 (General Technical Requirements for Testing Machines), and GB/T 28289 (Test Methods for Composite Properties of Aluminum Alloy Thermal Barrier Profiles).
