FNIRSI

You are trying to solder a large ground plane, but your FNIRSI station’s 75W ceramic heater just can’t get the job done. This is a common frustration when the heat sinks away faster than your iron can replace it. The real issue is thermal mass. A 75W element struggles to maintain temperature against a massive … Read more

7 best FNIRSI Multimeter for soldering iron When you’re troubleshooting a soldering iron or fine-tuning a circuit, you need a meter that can read voltage, spot noise on a scope, and maybe even generate a test signal. I’ve spent time with seven FNIRSI combos that do exactly that, from the 2C53T’s 50MHz bandwidth and 250MS/s … Read more

3 best FNIRSI Multimeter for automotive repair If you’re wrenching on modern cars, you know a basic multimeter won’t cut it—you need TRMS accuracy for tricky waveforms and enough counts to read sensors without guessing. I tested three FNIRSI models that actually hold up in a greasy garage, and one of them blew me away … Read more

3 best FNIRSI LCR Meter for inductor testing If you’re trying to measure inductors accurately — especially small-value ones or ferrite cores — you already know most cheap multimeters won’t cut it. You need a dedicated LCR meter that can push enough test frequency to actually read the inductance, and that’s exactly what FNIRSI builds … Read more

3 best FNIRSI LCR Meter with ESR measurement If you repair electronics, you already know that bad capacitors and failed components are the usual suspects. The problem is finding them quickly without dragging out a benchtop LCR bridge. I tested three FNIRSI LCR meters with ESR measurement to see which one actually saves you time … Read more

3 best FNIRSI LCR Meter for circuit board troubleshooting If you’ve ever stared at a dead circuit board wondering which capacitor is the problem, you already know the struggle. A good LCR meter takes the guesswork out of troubleshooting by measuring capacitance, inductance, and resistance with real accuracy. That’s exactly why I spent time with … Read more

3 best FNIRSI LCR Meter for precise measurements Finding the right LCR meter for precise measurements can be a headache. You need something that reads caps, inductors, and resistors accurately without costing a fortune. I spent weeks testing three top FNIRSI models to see which one actually delivers on its specs. I picked these three … Read more

5 best FNIRSI LCR Meter for battery testing If you’re tired of guessing whether a battery is dead or just deeply discharged, you need a meter that measures internal resistance and ESR. I’ve spent weeks testing FNIRSI’s lineup to find the best FNIRSI LCR meter for battery testing, because a battery that looks fine on … Read more

3 best FNIRSI LCR Meter for reverse engineering If you’re like me and spend your weekends digging into old boards or cloning circuits, you know the pain of guessing a capacitor’s value or chasing a phantom resistor. The best FNIRSI LCR meter for reverse engineering has to be fast, accurate, and handle those tiny SMD … Read more

3 best FNIRSI LCR Meter for capacitor testing If you troubleshoot electronics regularly, you know a bad capacitor can hide behind a good voltage reading. I’ve spent weeks with these three FNIRSI LCR meters to find which one actually makes capacitor testing fast and accurate. The LC1020E hits 100kHz with 19,999 counts, while the tweezer … Read more
