If not does atlas make one that does test both ?** A: This Atlas model doesnot measure resistors and capacitor, but you can do it with the Mega 328 ESR transistor, resistor, diode, capacitor and mosfet tester for less than $15.00 . **Q: Does this only identify the component or does it test it as well?** A: It not only identifies the type of transistor but gives you key current/voltage and gain characteristics also. **Q: Will this device check or test and specify thyristors?** A: Yes. **Q: Is this version 3.0?** A: Mine is a version 2.93 but I bought it in Jan 2013!! Not sure what the current selling rev is.. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice analysis, great price. *by C***Y on January 21, 2026* Great transistor analyzer.
