FNIRSI DMT-99 vs DMC-100 vs S1: Best Digital Multimeter for Home Use? I’ve been testing three popular FNIRSI multimeters — the DMT-99, the DMC-100 clamp meter, and the S1 — to figure out which one actually belongs in your home toolkit. All three pack 9999-count True RMS measurement, but they go about it in very … Read more

FNIRSI 2C53P vs 2D15P vs DPOS350P: Best Tablet Oscilloscope for Lab Work? I’ve spent serious time with all three of FNIRSI’s latest tablet oscilloscopes — the 2C53P, the 2D15P, and the beastly DPOS350P — to figure out which one actually belongs on your lab bench. The 2C53P is a 50MHz 3-in-1, the 2D15P bumps that … Read more

FNIRSI LCR-P1 vs FNIRSI LCR-ST1: Best Transistor Tester for Component Testing? I’ve been testing the FNIRSI LCR-P1 and the FNIRSI LCR-ST1 side-by-side to help you decide which component tester fits your bench. The LCR-P1 is a versatile transistor tester with a 1.44-inch screen and NEC infrared analysis, while the LCR-ST1 is a compact 10kHz LCR … Read more

FNIRSI FNB58 vs FNB-C2 vs FNB48P: Best USB Tester for Fast Charging? If you’re trying to figure out which USB tester can actually handle your fast chargers, you’re looking at three of FNIRSI’s best: the FNB58 (4-28V, 7A), the new FNB-C2 (4-50V, 6.5A, 240W), and the FNB48P (4-24V, 6.5A). All three can trigger protocols like … Read more

FNIRSI DMT-99 vs DMC-100 vs HRM-10: Best Battery Tester for Maintenance? I’ve spent time testing the FNIRSI DMT-99 multimeter, the DMC-100 clamp meter, and the HRM-10 battery tester, and they each serve a different purpose despite all being from FNIRSI. The DMT-99 is a 9999-count TRMS multimeter with recording modes, the DMC-100 is a 600A … Read more

FNIRSI 2D15P vs FNIRSI 1013D Plus: Best Oscilloscope for Automotive Diagnostics? If you’re shopping for an oscilloscope to use in your garage or workshop, you’re probably looking at the FNIRSI 2D15P and the FNIRSI 1013D Plus. Both are 2-channel, 100MHz portable scopes, but the 2D15P packs in a multimeter and signal generator, while the 1013D … Read more

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
