The Leak Tester (G520) is a flow-type leak detection instrument that utilizes high-precision electronic pressure regulating valves/manual valves to control test pressure. It is designed to inspect the airtightness of various components and finished products by measuring flow rates.
The device employs imported high-precision differential-pressure sensors and operates on the principle of laminar flow differential pressure flow measurement. Combined with a self-developed large-flow, small-volume pneumatic valve island, the G520 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.
◆ Laminar Flow Differential Pressure Flow Detection: Offers a flow resolution of <0.01 ml/min for exceptional accuracy.
◆ Imported High-Precision Differential-Pressure Sensors: Provides a differential pressure resolution of <0.1 Pa.
◆ 7-Inch Full-Touch Smart Operating System: Features a simple and intuitive Chinese/English interface for ease of use.
◆ Non-Heat-Generating, High-Flow Dedicated Pneumatic Valves: Ensures stable and efficient airflow control during testing.
◆ Self-Developed Valve Island: Reduces test time and enhances accuracy.
◆ Multiple Communication Interfaces: Includes built-in R232 serial port, RJ45 network port, USB communication interface, and LTP external I/O control port. ◆ Supports various communication protocols such as MODBUS RTU, MODBUS TCP, serial port, and TCP.
◆ 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.
