AMT-300
The AMT-300 Direct Pressure Air Tightness Tester is a portable seal leak detection instrument featuring a full-touchscreen design, specifically developed for mobile testing scenarios outside the production workshop. It combines high precision, high efficiency, and excellent stability, providing users with fast and accurate leak detection solutions. It is widely used in automotive 4S shops, repair shops, refrigeration equipment maintenance sites, and other locations – making it an ideal choice for after-sales service and on-site testing. The AMT-300 performs leak detection based on the pressure decay (direct pressure) method, which is one of the most common and efficient sealing test techniques. During testing, the instrument fills the workpiece with compressed air until the set pressure is reached, then shuts off the air supply, isolates the pressure, and precisely measures the pressure decay (loss) over a defined period. If the pressure loss exceeds a preset threshold, the product is judged to have a leak. This method is simple to operate and provides intuitive results, making it highly suitable for rapid on-site testing.

Technical Advantage
Premium Hardware Configuration
High‑quality sensors and high‑performance pneumatic valve groups, combined with a precision pneumatic system, ensure repeatability and long‑term stability of test results – fundamentally guaranteeing the instrument’s reliability.
Intelligent Software System
Built‑in advanced embedded system supports multiple test methods (positive pressure, negative pressure, etc.) to flexibly meet different testing requirements. Test results are displayed intuitively as leak rate or pressure change, providing operators with accurate data support.
Real‑Time Online Statistics
Powerful data statistics function records and analyzes test data in real time, providing a solid foundation for quality traceability and process improvement.
Intuitive Human‑Machine Interaction
True‑color LCD screen with truly programmed design; the operation interface is simple and intuitive. Button layout follows ergonomic principles for comfortable feel and durability, suitable for harsh production environments.
Visual Status Feedback
Front panel integrates a power switch for clear status indication. The start/stop button features a built‑in red/green dual‑color LED ring that corresponds directly to the OK/NOK result on the screen – keeping you fully informed of test progress and pass/fail results.
