FNIRSI LC1020E vs FNIRSI LCR-P1: Best LCR Meter for Capacitor ESR Testing? I’ve been testing two popular FNIRSI meters side by side — the LC1020E and the LCR-P1 — to figure out which one actually delivers for capacitor ESR work. The LC1020E is a dedicated 19,999-count LCR meter with 100kHz test frequency, while the LCR-P1 … Read more

FNIRSI DMC-100 vs FNIRSI TDM-120P: Best Thermal Clamp Meter for Electricians? I’ve been testing two of FNIRSI’s most talked-about meters: the DMC-100 digital clamp meter with 9999 counts and 600A capacity, and the TDM-120P, a 2-in-1 thermal imaging multimeter with 19999 counts. The big question is whether you need the thermal camera or if the … Read more

FNIRSI DSO152 vs DSO-510 vs DSO-TC3: Best Beginner Oscilloscope? I’ve spent a good chunk of time testing three of FNIRSI’s most popular handheld oscilloscopes for beginners: the DSO152, the DSO-510, and the DSO-TC3. Each one is a pocket-sized digital scope, but they differ wildly in bandwidth, sampling rates, and extra features, from the DSO152’s 200KHz … Read more

FNIRSI LC1020E vs LCR-ST2 vs LCR-ST1: Best LCR Meter for Precision? I’ve spent serious time with all three of these FNIRSI LCR meters — the LC1020E bench unit, the LCR-ST2 tweezer, and the LCR-ST1 budget tweezer — and they each serve a different crowd. The LC1020E pushes a 100kHz test frequency with a 19,999-count display, … Read more

FNIRSI LCR-P1 vs LC1020E vs LCR-ST2: Best Component Tester for Electronics Repair? If you’re into electronics repair, you’ve probably wondered which FNIRSI tester to grab. I’ve been testing the LCR-P1 transistor tester, the LC1020E 100kHz LCR meter, and the LCR-ST2 tweezer meter to see how they handle capacitors, resistors, and transistors. The LCR-P1 is a … Read more

FNIRSI DMC-100 vs DMT-99 vs TDM-120P: Best Clamp Meter for Electricians? I’ve been testing three FNIRSI meters side-by-side: the DMC-100 clamp meter with 9999 counts and 600A curve recording, the DMT-99 multimeter with recording and monitoring modes, and the TDM-120P thermal imaging multimeter with 19999 counts. Each serves a different type of electrician, and picking … Read more

FNIRSI LCR-P1 vs FNIRSI LCR-ST1: Best Component Tester for Electronics Repair I’ve been testing two popular FNIRSI component testers side by side: the LCR-P1 transistor tester and the LCR-ST1 10KHz LCR meter tweezer. Both are battery-powered and designed for measuring capacitors, resistors, inductors, and diodes, but they take very different approaches to the job. If … Read more

FNIRSI 2C53T vs 2C23T Handheld Oscilloscope: Best Beginner’s Scope? I’ve been testing the FNIRSI 2C53T and the FNIRSI 2C23T side-by-side, and honestly, picking the right one for a beginner comes down to bandwidth and what you plan to measure. The 2C53T packs a 50MHz bandwidth with 250MSa/s sampling, while the 2C23T sticks with a more … Read more

FNIRSI DSO152 vs FNIRSI DSO-510: Best Pocket Oscilloscope for Hobbyists? I’ve been testing two of FNIRSI’s most popular pocket oscilloscopes — the DSO152 and the DSO-510 — and honestly, they serve very different types of hobbyists. The DSO152 is a super affordable 200KHz bandwidth scope with a 2.5MS/s sampling rate, while the DSO-510 bumps things … Read more

FNIRSI 2C53P vs FNIRSI 2D15P: Best Tablet Oscilloscope for Automotive Diagnostics? I’ve spent time with both the FNIRSI 2C53P and the newer FNIRSI 2D15P to see which one actually helps you diagnose car problems faster. The 2C53P packs a 50MHz bandwidth with 250MS/s sampling, while the 2D15P jumps to 100MHz bandwidth and 500MS/s sampling — … Read more
