The Liquid Gating Intelligent Tester & Analyzer is a professional-grade teaching measurement instrument designed for intelligent pressure threshold testing and analysis of liquid gating membranes. This instrument integrates cross-membrane fluid control, real-time measurement under various external conditions, and display functions. Equipped with a cloud platform that supports LAN/WIFI capabilities, it allows remote monitoring and measurement via computer or mobile app. Users can select different measurement ranges to achieve high-precision real-time monitoring of pressure changes during fluid transmembrane processes. Coupled with AI big data for synchronous analysis of experimental data, it aids students in understanding the fundamental scientific issues related to liquid/solid interfacial property measurements, particularly the competitive relationship of interfacial tension in multiphase fluids. Additionally, this instrument can be used for transmembrane pressure performance tests and effective pore size measurements of other porous materials, enabling specific detection of trace substances through liquid gating design.
