This and other handy little allinone electronics/semiconductor tester, LCR meter can be purchased here https://amzn.to/2tRTFeS.'>https://amzn.to/2tRTFeS. This is sold under different brand names such as Drok and Kuman.
We purchased online from amazon from the Drok seller but I just noticed the Kuman claims it comes with a manual (mine did not) and is a few dollars cheaper at $28 so try it and let me know what you think.

Handy little electronics test equipment that is well worth the price to me. We will compare it to some others tester such as Atlas SCR Tester, DER EE DE5000, etc

Product description
Kuman Multifunctional transistor tester for automatic detection of NPN and PNP transistors, Nchannel and Pchannel MOSFET, diodes, thyristors, resistors, capacitors or other devices. Easy and convenient to operate.
Specifications:
Display: 1.8" TFT Color Display
Material: PCB + Plastic
Shutdown Current: 20nA
Resistor Test Range: 0.5Ω50MΩ
Inductor Test Range: 0.01mH20H
Capacitor Test Range: 25pF100000uF (please make sure that capacitors are discharged before testing)
Resolution of resistor measurement: 0.1 ohms (the maximum measured value is 50M OHMS)

Features:
*It can measure the Current amplification factor of bipolar transistor (B), breakover voltage of emitter junction (Uf), the threshold voltage of MOSFET, grid capacitance, two resistors and potentiometer. (If the potentiometer is adjusted to one of the ends, the tester can not distinguish the pin of middle and two ends.)
*It can detect bipolar transistor, protect diode inside MOSFET and equivalent series resistance(ESR) of a more than 2UF capacitor.
