AT02 is a high-precision digital air leak tester built for automotive maintenance, delivering 1Pa resolution for fast, reliable leak detection.
Featuring a 7.0-inch HD touchscreen, built-in air pump, and rechargeable battery, it enables fully mobile testing without external air or power sources. Customizable test parameters ensure repeatable results, making it ideal for both general automotive checks and EV battery pack testing.
High-Resolution Detection：Delivers pressure resolution down to 1 Pa for precise and stable air tightness testing.
Wide Pressure Test Range：Supports adjustable testing from 0 to 30 kPa for conventional components and EV battery packs.
Integrated Air Pump：The built-in air pump eliminates the need for an external compressed-air source.
Dual Power Supply：Supports both lithium battery and adapter power for flexible use in different working environments.
Cordless Mobile Testing：The large-capacity lithium battery enables convenient on-site testing without an external power connection.
Advanced Safety Monitoring：Equipped with automatic overpressure cutoff and built-in adapter voltage detection, it effectively protects battery packs and prevents equipment damage during testing.
Real-Time Test Visualization：Clearly displays test data, progress, and stage duration throughout the entire testing process.
Customizable Test Procedures：Allows independent adjustment of pressure, inflation, stabilization, testing, and exhaust parameters for reliable results.
