AMT-400
The AMT‑400 Four‑Channel Direct Pressure Air Tightness Tester is a multi‑channel leak testing device with a full‑touchscreen interface. Integrating four independent test stations, high precision, and high efficiency, it can simultaneously perform leak detection on four products or multiple test points, significantly boosting testing efficiency. The AMT‑400 is ideal for mass production environments, helping enterprises achieve both increased capacity and quality control. The AMT‑400 performs leak detection based on the pressure decay (direct pressure) method, with each channel operating independently. During testing, each channel fills its respective 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 over a defined period. If the pressure loss in any channel exceeds a preset threshold, the corresponding product is judged as leaking. With four channels working in parallel without interference, the average test time per part is significantly reduced.

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.
