An LCR meter measures the three passive quantities a multimeter handles poorly, and the useful ones add a test frequency and a secondary parameter such as ESR or dissipation factor. This hub sorts the current listings into true LCR meters, multimeter hybrids and automatic component testers, using only the figures each manufacturer publishes.

These ten were chosen from the LCR meters and component testers we hold verified listings for. They are compared on the measurements the manufacturer states, the test frequency, the resolution or counts figure, the secondary parameters shown alongside the main reading, and whether the instrument identifies a part on its own. We did not run laboratory tests, and every blank in the table is marked Not stated rather than filled with a guess.

Every figure here is taken from the manufacturer listing at the time of research. Where a listing gives no value the cell reads Not stated; we have not substituted figures from datasheets, forums or comparable models. Counts and resolution are not the same as accuracy, and none of these listings publishes a basic accuracy percentage.
Four questions settle which of the three families above you actually need:
Capacitance and inductance both change with test frequency. If you are matching parts to a design, you need a stated and selectable frequency. If you are deciding whether a motor capacitor has failed, you do not.
A tired electrolytic capacitor often reads close to its marked value while its equivalent series resistance has climbed. Only the LC1020E and the two FORIOT testers state ESR on their listings.
Automatic component testers exist to identify parts you cannot read. If everything you measure is already labelled, that feature buys you nothing and a proper LCR meter buys you more.
A multimeter hybrid such as the LCR600 covers live circuits and loose components in one body. A dedicated LCR meter does one job better but sits on the bench beside a multimeter.
Two things. It measures inductance, which most multimeters omit entirely, and it measures at a defined test frequency rather than whatever the meter happens to use. Better instruments also report a secondary parameter alongside the main reading, such as equivalent series resistance or dissipation factor, which is usually what reveals a failing capacitor.
Because real components are not ideal. A capacitor has series resistance and inductance, an inductor has winding capacitance, and the balance between them shifts with frequency. Measuring a part near the frequency it will work at gives a value that means something in the circuit. A meter that does not state its test frequency is giving you one unlabelled point.
No. Equivalent series resistance is the resistive loss inside a capacitor at the test frequency, and it is measured with the capacitor in circuit terms rather than as a DC resistance. A capacitor can read its correct capacitance and still have an ESR high enough to make a power supply fail, which is why the parameter exists as a separate reading.
For identification and rough values, generally yes; for characterisation, no. None of the listings for the LCR-P1, LCR-TC1 or LCR-T4 family publishes an accuracy figure or a test frequency. Use them to find out what a part is and whether it is roughly in range, then verify anything critical on an instrument that states its conditions.
Usually not reliably. Everything else connected across the part is measured in parallel with it, so the reading is the network rather than the component. Lift one leg, or remove the part. Discharge any capacitor before measuring it, and never connect an LCR meter to a live circuit; these instruments apply their own test signal and are not rated for energised work.
The LC1020E is the pick for anyone who understands why test frequency matters. A capacitor measured at 100 Hz and the same capacitor measured at 100 kHz can give different values, and an inductor behaves differently again, so a fixed-frequency meter tells you one point on a curve and calls it the answer. FNIRSI states a selectable frequency up to 100 kHz on this listing, which is the specification that separates it from every other instrument on this page.
The second thing it does that the cheap testers do not is show a main and a secondary parameter at the same time. The listing names X (reactance), D (dissipation factor), Q (quality factor), theta (phase angle) and ESR. On an electrolytic capacitor, ESR is usually the number that tells you the part has failed while the capacitance reading still looks acceptable, so having it beside the main value saves a second measurement.
Resolution is stated at 19,999 counts, which is four and a half digits, and the meter also has an AUTO mode that decides for itself whether it is looking at an inductor, a capacitor or a resistor. The listing does not publish a basic accuracy percentage, a measurement range for each quantity, or a battery runtime, so a buyer who needs those figures for a calibration record has to ask FNIRSI.
Most technicians who say they need an LCR meter actually need a multimeter that can also read inductance. The LCR600 is built for that person. The listing states a 6000-count auto-ranging digital multimeter with AC and DC voltage, current, resistance, inductance, frequency, duty cycle, diode and continuity, which is a full multimeter function set with the L of LCR bolted on.
The practical consequence is that one tool goes in the bag instead of two. Checking a motor run capacitor, then measuring the supply voltage at the terminals, then testing continuity on a winding is three instruments on most benches and one here. For field service on motors, ballasts and small transformers that is a real saving.
What you give up is precision and control. The listing states no test frequency, no secondary parameter such as ESR or dissipation factor, and no basic accuracy figure, so this is a meter for deciding whether a part is roughly right rather than for characterising it. A 6000-count display is also three and a half digits against the four and a half of the LC1020E. Treat it as a multimeter that happens to read inductance, not as a replacement for a bench LCR bridge.
The LCR-P1 belongs to a different family from the two picks above. It is an automatic component tester: you put an unidentified part into the socket, press one button, and the instrument works out what it is and reports the relevant parameters. FNIRSI states measurement and analysis of surface mount components, NPN and PNP transistors, MOS and field effect transistors, and the passive quantities alongside them.
That makes it the right tool for salvaged parts, unmarked stock and boards where the silkscreen has been rubbed off, and the wrong tool for a designer who needs a capacitor characterised at a specified frequency. There is no frequency selection because the instrument chooses its own test conditions, and the listing publishes no accuracy figure for any quantity.
Four more testers in the table below do the same job with slightly different housings and displays, including the LCR-TC1 pattern sold by diymore, FORIOT and others, and the long-running HiLetgo LCR-T4. They differ mainly in screen and case rather than in what they measure, so the choice among them is mostly about which one is available.
Short answer: the FNIRSI LC1020E is the meter to buy if the reading has to mean something, because it is the only one here that states a selectable test frequency up to 100 kHz and shows ESR beside the main value; the LCR600 is the sensible choice for a technician who wants one instrument that reads inductance and still works as a full multimeter; and the FNIRSI LCR-P1 is the tool for unmarked and salvaged parts, where identification matters more than precision.
The ten products on this page fall into three groups that are not interchangeable. A handheld LCR meter applies an AC test signal at a known frequency and reports inductance, capacitance or resistance with a secondary parameter beside it. A multimeter hybrid adds an inductance range to an otherwise ordinary meter and rarely states the conditions it used. An automatic component tester identifies an unknown part and reports whatever parameters suit it, choosing its own test conditions without telling you what they were. All three get listed as LCR meters. Only the first is one in the sense a designer means, and the table above splits them by type so the comparison is between like and like.
A capacitance reading on its own answers one question: is the part the value it claims to be. It does not answer the more common one, which is whether the part still works. Electrolytic capacitors fail by drying out, and the first symptom is a rise in equivalent series resistance rather than a fall in capacitance, so a failed part can read correctly on a meter that shows only the main value. Dissipation factor and quality factor describe the same loss from different directions and appear on the same displays. On this page only the FNIRSI LC1020E and the two FORIOT testers state that they show ESR; everything else reports the headline number alone. If your work is repair rather than design, that single specification is the one to sort by.
Two figures appear on these listings and neither is accuracy. Counts describe how finely the display divides a range, so the 19,999 counts of the LC1020E resolve more steps than the 6000 counts of the LCR600. Resolution is how small a change the display can show. Accuracy is how close the reading is to the true value, expressed as a percentage of reading plus a number of digits, and not one of these ten listings publishes it. That is worth knowing before you buy on a counts figure: a high-resolution display can show an unstable, inaccurate reading to four and a half digits. Where a specification matters for a record or a calibration note, ask the manufacturer directly rather than inferring it from the display specification.
An LCR meter is a component instrument, not a circuit tester. It supplies its own small AC signal and none of the instruments here states a CAT rating or a voltage rating for connection to a live circuit, so treat all of them as strictly off-circuit tools. Isolate the equipment, discharge capacitors through a suitable resistor before touching them, and lift at least one leg of any part you want a clean reading on. Large motor run and start capacitors hold a dangerous charge long after power is removed, and a charged capacitor connected to an LCR meter can damage the instrument as well as the person holding it. The CAMWAY listing is the one in this group that states a self-discharge function; on the rest, discharge is your job.
This hub sits above the more specific measurement guides on the site. Each one below answers a narrower question:
If the parts you measure are motor capacitors, fan capacitors and ballast components, buy the hybrid and spend the difference on a decent clamp meter. If they are board-level electrolytics on power supplies, buy the instrument that states ESR. If they are unlabelled parts out of a drawer, buy the automatic tester, which costs least and answers the question you are actually asking. Very few people need all three, and nobody needs the automatic tester and the hybrid at the same time.
Instruments were compared on manufacturer listing text only: the quantities the listing states, secondary parameters named, test frequency, counts or resolution, display type and whether automatic component identification is offered. Owner feedback was reviewed for recurring reports of unstable readings and failed units. We ran no laboratory tests and publish no measurements of our own, and we did not substitute figures from datasheets for models whose listing is silent. Amazon data supplies images, availability and links only.
