I made NMOS VTO-tester with 2SK4150 and Mini DC Digital Voltmeter(Rin=120k ohm) and 9V-battery, but not yet PMOS-tester.I tested several FETs(each for 10).
2SK2232=1.33+-0.016,IRFI44N=3.11+-0.011,IRFZ44N=1.40+-0.042,FKI06269=2.17+-0.060,IRFI3205=2.80+-0.023,FKI10531=2.17+-0.010,2SK3067=2.71+-0.058,IRLI520N=1.62+-0.015...........,
