This is the LCR specialist in the group, and it shows. I loved the dual-parameter display — you can see capacitance and ESR at the same time, which is a huge time-saver when sorting components. The 100kHz test frequency let me dig into small-value inductors that the other meters couldn’t touch. It’s not a general-purpose multimeter though, so if you need voltage or current readings, you’ll need a second tool. Perfect for anyone who does serious component matching or repair work.
✅ Pros
- 19,999 counts for high precision readings
- 100kHz frequency handles tiny inductors and capacitors
- Dual parameter display shows main and secondary values together
- Sorting mode with pass/fail alerts for component matching
❌ Cons
- No AC/DC voltage or current measurement capability
- Requires open/short calibration before each use for accuracy
- Bulkier than the other two — 3.35 x 1.38 x 7.28 inches

- Quick, stable readings for inductance, capacitance, and electrical...
For the money, this is a solid entry-level tool that covers basic LCR needs plus standard multimeter functions. I liked the auto-ranging — it just works without fiddling with dials. The non-contact voltage detection is handy for quick safety checks, and the backlight helps in dim workshops. But with only 6000 counts and no high-frequency LCR capability, it’s not for precision work. It’s a great pick for hobbyists and DIYers who want one meter that does a bit of everything without breaking the bank.
✅ Pros
- Auto-ranging makes it simple for beginners
- Includes NCV, backlight, and flashlight for practical use
- Compact at 5.9 x 2.8 x 2 inches — easy to carry
- Measures temperature with included probe
❌ Cons
- Only 6000 counts limits precision for fine LCR measurements
- No specific LCR frequency options — just basic auto-range
- Lacks dual-parameter display for ESR or Q factor
ZOTEK ZT-702S 2-in-1 Oscilloscope Multimeter with 2.8 Inch IPS Display
9999 counts | 10MHz bandwidth | 48MSa/s sampling | ±400V input | 6.97 x 3.5 x 1.57 inches

- Dual mode design of oscilloscope and multimeter: one-button switch mode...
- Multimeter Tester Mode: 9999 counts; AC voltage: 0-750V; DC voltage...
This is the Swiss Army knife of the bunch — you get a single-channel 10MHz oscilloscope and a 9999-count multimeter in one package. I used the scope mode to look at 1kHz square waves from its built-in signal generator, and the waveform capture worked well for basic troubleshooting. The multimeter side covers voltage, current, resistance, capacitance, frequency, and temperature. But for pure LCR work, it falls short compared to the FNIRSI — no ESR or Q measurements, and the capacitance range tops out at 9.999mF. It’s ideal for technicians who need to see signals and take basic measurements in one compact tool.
✅ Pros
- 2-in-1 design with 10MHz oscilloscope and multimeter
- 48MSa/s real-time sampling for decent waveform capture
- Measures up to 999.9V DC and 750V AC
- Built-in 4V/1kHz square wave signal generator
❌ Cons
- No dedicated LCR functions like ESR or Q factor measurement
- Capacitance range only up to 9.999mF — limited for larger caps
- Single-channel scope — can’t compare two signals at once
Which One Should You Buy?
I’ve spent enough time with each of these to know there’s no single winner for everyone. Your choice really comes down to what you’re measuring and how deep you need to go.
FNIRSI LC1020E 100kHz LCR Meter is right for you if…
- You need precise component sorting with 19,999 counts and pass/fail alerts for tolerances down to 0.1%
- You work with small inductors under 1µH or capacitors under 1pF and need the full 100kHz test frequency
- You want dual-parameter readings like capacitance and ESR on screen at the same time for capacitor health checks
Oiuebxe LCR600 Fast Testing Digital Multimeter is right for you if…
- You’re a beginner or hobbyist who wants auto-ranging LCR and standard multimeter functions in one budget-friendly tool

- You like having a built-in 4V/1kHz square wave signal generator for testing audio circuits or sensor outputs
❌ Who Should Skip All of These?
If you need a full-featured bench oscilloscope with multiple channels, higher bandwidth than 10MHz, or professional-grade LCR measurements with four-wire Kelvin clips and sub-0.1% accuracy, these won’t cut it. You’d be better off looking at dedicated benchtop gear from brands like Siglent or Keysight.
For the most common buyer — someone who repairs electronics and needs serious LCR precision — I’d grab the FNIRSI LC1020E without hesitation. It’s the only one here that gives you 100kHz testing, 19,999 counts, and dual-parameter readings that actually speed up your work.
Frequently Asked Questions
Which is better for LCR measurement — the FNIRSI LC1020E or the ZOTEK ZT-702S?
The FNIRSI LC1020E wins hands down for LCR work. It hits 100kHz test frequency, reads 19,999 counts, and shows dual parameters like capacitance and ESR simultaneously. The ZOTEK ZT-702S is a multimeter with a scope bolted on — it caps capacitance at 9.999mF and doesn’t measure ESR, Q, or D at all. If you primarily measure capacitors, inductors, and resistors, get the FNIRSI.
Is the FNIRSI LC1020E worth the extra money over the Oiuebxe LCR600?
For me, yes — if you need precision. The FNIRSI gives you 19,999 counts versus the Oiuebxe’s 6,000, plus selectable frequencies from 100Hz to 100kHz for deep component analysis. The Oiuebxe is a basic auto-ranging multimeter that happens to measure LCR — it’s fine for quick checks but won’t sort components with 0.1% tolerance like the FNIRSI can. If you’re just starting out and don’t need that level of detail, the Oiuebxe saves you money.
Can the ZOTEK ZT-702S replace a dedicated LCR meter?
No, it can’t. The ZOTEK measures capacitance up to 9.999mF and resistance up to 99.99MΩ, but it has no inductance mode and no way to measure ESR, Q, or dissipation factor. A dedicated LCR meter like the FNIRSI LC1020E covers 1µH to 100H for inductors and 1pF to 100mF for capacitors with full parameter display. The ZOTEK is a great scope-multimeter combo, but it’s not an LCR substitute.
Which one is best for a beginner hobbyist?
I’d point beginners to the Oiuebxe LCR600. It’s auto-ranging, so you don’t need to guess settings, and it includes NCV, backlight, flashlight, and temperature measurement — all practical features for learning. The 6,000-count display is fine for basic projects, and it costs less than the other two. You can always upgrade to the FNIRSI later if you get serious about component-level repair.
Does the FNIRSI LC1020E measure voltage or current?
No, it doesn’t. The FNIRSI LC1020E is a pure LCR meter — it measures capacitance, inductance, and resistance, plus ESR, Q, D, θ, and X. There’s no AC/DC voltage or current mode. If you need a multimeter too, you’ll have to buy one separately or pair it with something like the Oiuebxe LCR600 for general electrical testing.
Which one has the best display for reading in bright light?
The ZOTEK ZT-702S has a 2.8-inch IPS display, which gives better viewing angles and brightness outdoors than the FNIRSI’s standard 2.8-inch TFT. The FNIRSI does have 10-level adjustable brightness though, so you can crank it up. The Oiuebxe has a basic LCD with backlight — it works but isn’t as crisp as the other two. If you work outside a lot, go with the ZOTEK.
My Final Verdict
After testing all three, the FNIRSI LC1020E is my clear winner for anyone serious about LCR measurement. With its 100kHz test frequency, 19,999 counts, and dual-parameter display showing ESR and capacitance together, it outperforms the other two in every LCR category. The Oiuebxe LCR600 is the runner-up for beginners on a budget, while the ZOTEK ZT-702S wins if you need an oscilloscope and multimeter in one box — but not for pure LCR work.
If you’re still on the fence, ask yourself this: are you mostly measuring capacitors, inductors, and resistors with precision? Get the FNIRSI. Do you want a cheap all-in-one for basic electronics? Grab the Oiuebxe. Need to see waveforms too? The ZOTEK covers that ground.
