LCRT7 transistor tester supports testing TFT, diode, triode, capacitance, and also functions as an LCR ESR meter. It can test NPN and PNP transistors, MOSFETs, and IR components, covering common device families used in today’s circuits. This multifunction tester combines multiple testing functions in one device, reducing the need for separate instruments. It measures various electrical parameters accurately, providing reliable data for component evaluation and circuit diagnosis. With its diverse testing functions, it is a practical tool for electronics enthusiasts and professionals to detect, identify, and analyze different components. Use scenarios: - In a repair or prototyping workflow, quickly identify transistor types, check capacitance, and assess ESR of capacitors to diagnose circuit issues. - In a service lab, verify MOSFETs and IR components to confirm they meet specification before replacement. - For hobbyists, characterize discrete components and validate components before integrating them into projects.
