The Leak Tester (E620) is a differential-pressure type leak detection instrument that utilizes external control for test pressure management. It is designed to inspect the airtightness of various components and finished products, including those without inflation ports (quantitative detection). The device can be connected to a touchscreen display and supports MODBUS TCP communication via an RJ45 network port.
Equipped with imported high-precision differential-pressure sensors and a self-developed large-flow, small-volume pneumatic valve island, the E620 enables automated testing of all products under different conditions.
◆ 24-bit A/D Sampling and 32-bit MCU: Ensures high-precision data acquisition and processing.
◆ Switchable Testing Modes: Supports differential pressure, direct pressure, volume, and blockage modes for versatile testing needs.
◆ High Accuracy with Differential Pressure Resolution <0.1Pa: Delivers exceptional measurement precision.
◆ Non-Heat-Generating, High-Flow Dedicated Pneumatic Valves: Ensures stable and efficient airflow control during testing.
◆ Temperature Compensation, Transient Compensation, and Self-Learning Calibration Functions: Guarantees the repeatability and reliability of test data.
◆ Self-Developed Valve Island with a Test Chamber Volume of Only 2ml: Reduces test time and enhances accuracy.
◆ Multiple Communication Interfaces: Includes built-in R232 serial port, RJ45 network port, and LTP external I/O control port. Integrated barcode scanner and standard leak port interfaces, supporting MODBUS TCP and 232 communication modes.
◆ 100 Subroutines with Individual Programming and Combinable Options: Allows for customized and complex testing scenarios to meet diverse requirements.
◆ Data Storage and Export: Capable of storing 60,000 sets of test data and supports USB data export.
