Product details

Atlas DCA55 Semiconductor Analyser

• Analyser allows you to identify a variety of semiconductors
• The DCA55 supports semiconductors such as transistors, MOSFETs, diodes, JFETs and more
• Test for gain and leakage on transistors, gate thresholds on MOSFETs and more
• Includes one 23A battery
• Measures just 103mm x 70mm x 20mm

What can I do with the DCA55?
The DCA55 will automatically identify and measure a wide range of semiconductor devices. It can identify the type and pinout of the part being tested. It supports bipolar NPN/PNP transistors, Darlingtons, diode-protected transistors, transistors with built-in resistors, enhancement mode MOSFETs, depletion mode MOSFETs, diodes, diode networks, LEDs, two and three lead bicolour LEDs, JFETs and many more.

How easy is this meters to use?
This analyser is very simple to read and use. It automatically detects what you are trying to test and will show you on the LCD screen everything you could want to test.
