ET500 is a high/low-voltage airtightness testing device for electric vehicle battery pack boxes and liquid cooling systems, suitable for scenarios
such as battery pack end-of-line production, power system assembly, and maintenance re-encapsulation testing
Features
- High and low pressure dual compatibility with a maximum detection range of 500kPa, suitable for liquid cooling systems and box testing.
- Physical separation of high- and low-pressure interfaces reduces misoperation risk and protects equipment.
- Built-in air filtration system filters moisture and impurities, protecting internal sensors and improving detection stability.
- One-button automatic standard process covering pressurization, pressure stabilization, judgment, and exhaust.
- 10-inch touch screen provides intuitive operation and clear real-time information display.
- Process visualization with real-time pressure curve display and clear testing progress.
- Automatic storage of historical test records for quality control and report output.
Functions
- High and low pressure testing: Supports up to 500kPa detection, suitable for liquid cooling and sealed box testing.
- Automatic testing process: Fully automated pressurization, stabilization, judgment, and exhaust for efficient operation.
