FNIRSI LCR-ST1 vs LCR-P1 vs LCR-ST2: Best SMD Tweezer for PCB Repair? If you’re repairing circuit boards, you know the pain of guessing whether a tiny capacitor or inductor is good or bad. I’ve been testing three FNIRSI models — the LCR-ST1 (10kHz tweezer), the LCR-P1 (transistor tester), and the LCR-ST2 (100kHz tweezer) — to … Read more

FNIRSI 1014D vs 1013D Plus vs 2D15P: Best Oscilloscope for High Frequency? If you’re shopping for a high-frequency oscilloscope under check current price on Amazon FNIRSI has three models that all look tempting on paper: the 1014D, the 1013D Plus, and the newer 2D15P. All three claim 100MHz bandwidth, but the sampling rates and features … Read more

FNIRSI LCR-P1 vs FNIRSI LCR-ST2: Best SMD Component Tester for Electronics Work I’ve been testing the FNIRSI LCR-P1 transistor tester and the FNIRSI LCR-ST2 100kHz LCR ESR meter tweezer side-by-side, and they’re both solid options for SMD work. The LCR-P1 is a versatile all-in-one tester with 600+ bought last month, while the LCR-ST2 brings a … Read more

FNIRSI LC1020E vs FNIRSI LCR-ST2: Best LCR Meter for Bench Testing? I’ve been testing two very different LCR meters from FNIRSI side by side: the LC1020E (a full-sized bench unit with a 2.8″ TFT display and 19,999 counts) and the LCR-ST2 (a compact tweezer-style meter built for SMD and through-hole components). Both hit 100kHz but … Read more

FNIRSI 2C23T vs 2C53T vs DST-201: Best Handheld Oscilloscope for Field Service? I’ve been testing three popular FNIRSI handheld oscilloscope multimeters side-by-side: the 2C23T with its 10MHz bandwidth and 50MSa/s sampling rate, the upgraded 2C53T boasting 50MHz and 250MSa/s, and the budget-friendly DST-201 with a 1MHz bandwidth and 5MSa/s sample rate. Choosing between them really … Read more

FNIRSI LCR-ST1 vs LCR-P1 vs LC1020E: Best SMD Component Analyzer? I’ve been testing three FNIRSI component analyzers side-by-side: the LCR-ST1 tweezer, the LCR-P1 transistor tester, and the LC1020E benchtop LCR meter. Each one handles SMD components differently, and the key difference comes down to portability versus measurement depth — the LC1020E goes up to 100kHz … Read more

FNIRSI DMT-99 vs FNIRSI DMC-100: Best Multimeter for Electricians? If you’re an electrician trying to decide between the FNIRSI DMT-99 and the FNIRSI DMC-100, you’re looking at two very different tools. The DMT-99 is a smart 9999-count TRMS multimeter with recording and monitoring modes, while the DMC-100 is a 600A clamp meter that also measures … Read more

FNIRSI 2C53T vs 2C53P vs 2D15P: Best Handheld Oscilloscope Multimeter for Pros? I’ve spent time with all three of these FNIRSI handheld oscilloscope multimeters, and I can tell you the choice isn’t obvious. The 2C53T is a budget-friendly 3-in-1 with a 50MHz bandwidth and 250MS/s sampling, while the 2C53P adds a 4.3-inch touch screen, and … Read more

FNIRSI 2C53T vs 2C53P vs 2C23T: Best Field Oscilloscope Multimeter? I’ve been testing three of FNIRSI’s most popular handheld all-in-one tools — the 2C53T, the 2C53P, and the 2C23T — to figure out which one actually makes sense for field work. All three pack an oscilloscope, multimeter, and signal generator into one portable device, but … Read more

FNIRSI DMT-99 vs FNIRSI S1 Smart Multimeter: Best Home Use Tester I’ve been testing two of FNIRSI’s most popular smart multimeters side by side — the DMT-99 with its 9999-count TRMS and recording capabilities, and the S1 with its compact electric pen design and automatic AC/DC voltage identification. Both are built for home users who … Read more
