Peak Atlas DCA Semiconductor Component Tester and Analyzer
The Peak Atlas DCA55 makes analyzing semiconductors and identifying transistors easy. It's small size and light weight make it super portable and the digital display allows you to take reads with no fuss. With it's in-depth reads and wide analysis portfolio, the Atlas DCA55 allows you to skip the data books when identifying components.
To operate your DCA55, simply connect the test clips and use the two on device buttons–no messing with wires and switches. All information is then displayed in scrollable format on the LED screen. It may be small, but this Atlas DCA has the ability to analyze a wide range of components.
Use this tester to help you repair audio equipment, computer monitors, and a slew of other useful electronics. With its auto power off feature and long battery life, the Atlas DCA55 will serve as your go-to tool for many projects to come.
