The DCA55 is an intelligent and flexible semiconductor analyzer that allows you to connect it in any way round. It features a backlit alphanumeric display that shows component type, pinout information, and parameter measurement. It supports a wide range of components such as transistors, MOSFETs, JFETs, diodes, LEDs, and many others.

Features:

Automatically identifies type of component, pinout, and other important parameters.
Supports transistor leakage measurement and Germanium/Silicon identification.
Fitted universal hook probes for easy connectivity.
Comes with a comprehensive illustrated user guide and AAA alkaline battery.
