FK907 In-Circuit Transistor Checker.
There are times when removal of a transistor from a PCB to check its functionality is not practical. The FK907 transistor checker can examine both NPN and PNP transistors whilst installed. Two, on-board LEDs are used to identify the transistor type and whether or not it is functional.
