22 listed manufacturers, 60 catalog entries: the September 2026 DirectIndustry industrial-supplier index lists 22 active LCR meter brands and 60 individual model entries, including Teledyne Test Tools, HIOKI, Tecpel, Tonghui, and GW Instek [S2].
Across the same index, benchtop models span 10 Hz to 300 kHz test frequency, while portable models run 1 Hz to 100 kHz, and the HIOKI 3532-50 stretches desktop LCR/ESR coverage to 5 MHz at ±0.08% basic accuracy [S2]. Reference pricing for budget handheld LCR meters starts around US$41 to US$55, with mid-range bench units at roughly US$244 on the Mastech commercial line [S9].
What counts as an LCR meter, and where the category splits
An LCR meter is an electronic test instrument that measures the three passive-component parameters, inductance L, capacitance C, and resistance R, and most modern units also resolve secondary parameters such as dissipation factor D, quality factor Q, equivalent series resistance (ESR), and impedance phase angle [S4][S8]. Two physical form factors dominate supplier catalogs: benchtop/bench instruments for laboratory and production-line work, and handheld/portable units for field service and on-board sorting [S2].
Within benchtop, suppliers further segment by maximum test frequency: sub-100 kHz general-purpose, 100 kHz to 1 MHz precision, and 1 MHz to 5 MHz high-frequency (often combined with ESR capability) [S3][S4]. IET Labs' 7660 covers 10 Hz to 2 MHz with 0.05% basic accuracy and measures 14 impedance parameters two at a time, while their GenRad 1693 (12 Hz to 200 kHz) reaches 0.02% accuracy with ±0.0001 Df resolution, a metrology-grade baseline referenced across the industry [S3].
Active 2026 supplier roster and what each brings to the table
The supplier base clusters in three manufacturing geographies: the United States (IET Labs/GenRad legacy instruments, Teledyne Test Tools, B&K Precision distribution), Japan (HIOKI, Texio Technology, Sanwa, Adex AX-series), and China (GW Instek, Tonghui, Mastech, OWON, Tecpel) [S2][S3][S5][S6][S7][S9].
Teledyne Test Tools T3LCR series delivers 10 Hz to 300 kHz coverage with 0.05% basic accuracy across three model tiers [S2]. IET Labs sells the 7660, 1910/1920 1 MHz units, and the legacy GenRad 1693/1689/1659 Digibridge line, with the 1693 explicitly positioned for ac resistance and low-frequency L/C metrology at 0.02% [S3]. GW Instek markets high-precision LCR meters alongside the LCR-6000 series from Texio Technology, which offers 5 models spanning 10 Hz to 300 kHz with 0.05% basic accuracy and 25 ms measurement time [S5][S7].
On the handheld side, Tecpel LCR-615 reaches 100 kHz at 0.1% accuracy, the UNI-T UT612 sits in the budget 100/120 Hz tier with CE/UKCA marking, and the Mastech MS6013 is priced at US$41.45, MS5308 at US$243.95 [S2][S9]. Adex's AX-221N and the Sanwa LCR701 (DC to 100 kHz) round out the Japanese handheld offerings, with the LCR701 listed in the 10,000 to 100,000 yen price band [S5].
Decision criteria: matching instrument class to measurement task
Frequency band is the first filter. Passive component sorting at audio rates (100 Hz, 1 kHz, 10 kHz) is served by the lowest-cost handhelds and bench units; precision inductor and capacitor characterization at 20 Hz to 200 kHz requires a 0.05% or better benchtop; RF/MEMS device and dielectric work pushes requirements to 1 MHz and above, where the HIOKI 3532-50 and IET 7660 sit [S2][S3][S4].
Basic accuracy is the second filter. Metrology labs and standards rooms target the 0.02% to 0.05% band, dominated by GenRad 1693/1689, IET 7660, and the GW Instek/Texio LCR-6000 series [S3][S5]. Production-line sorting accepts 0.1% to 0.3%, which is the standard for most handhelds including UT612 and LCR-615 [S2].
The IET 7660 precision LCR meter programs AC test voltage from 20 mV to 5 V and supports DC bias voltage of 2 V internal or 0 to 200 V external, while measuring 14 impedance parameters with 0.05% basic accuracy over programmable frequencies from 10 Hz to 2 MHz [S3]. Comparator and bin-sorting outputs, plus handler/SCAN and RS-232C interfaces, are standard on Texio LCR-6000 and IET 1910/1920 units, defining the production-line integration envelope [S3][S5].
Comparison: precision, frequency, and form factor across the major 2026 lines
Against four decision criteria (test frequency ceiling, basic accuracy, form factor, special features), the active 2026 lines line up as follows: GenRad 1693 (12 Hz to 200 kHz, 0.02%, benchtop, 30+ year service life for metrology); IET 7660 (10 Hz to 2 MHz, 0.05%, benchtop, 14 parameters and 14 sort bins); HIOKI 3532-50 (42 Hz to 5 MHz, ±0.08%, benchtop, 5 ms measurement, ESR focus); Teledyne T3LCR (10 Hz to 300 kHz, 0.05%, benchtop, SCPI programmable); Texio LCR-6000 (10 Hz to 300 kHz, 0.05%, benchtop, 25 ms speed, color LCD); Tecpel LCR-615 (1 Hz to 100 kHz, 0.1%, handheld, 5 fixed frequencies); UNI-T UT612 (100/120 Hz, 0.3% class typical, handheld, CE/UKCA marked) [S2][S3][S5].
Price tiers in the catalog show budget handhelds at roughly US$41 to US$55, mid-range handhelds around US$244, and benchtop pricing generally off-list and quote-driven, with Texio LCR-6000 series and IET/GenRad precision units requiring direct vendor contact for quotation [S3][S5][S9].
Who an LCR meter is for, and where it is not the right tool
LCR meters fit incoming-inspection, component-sorting, and engineering-bench characterization of discrete passives, including MLCCs under DC bias, wound inductors, transformers, and relay contact resistance [S3][S4][S8].
An LCR meter is not a vector network analyzer (VNA) and is not the right instrument above roughly 5 MHz where transmission-line and S-parameter behavior dominates [S4]. It is also not a substitute for a high-resistance meter or megohmmeter when leakage above 1 GΩ is the parameter of interest, a job that falls to dedicated high-resistance meters and electrometers, often combined with switching fixtures such as the multi-channel 10-channel dielectric test modules referenced in the DirectIndustry catalog [S2][S4]. The broader test-and-measurement context for plant-floor installations is covered in Sorting System Installation: Concrete Specs, Failure Modes, and Acceptance Tests.
Limitations, sourcing signals, and what to track next
Calibration traceability is the practical ceiling: the GenRad 1693 and 1689 lines are explicitly positioned for metrology environments with documented 0.02% accuracy and ±0.0001 Df, while most production handhelds are calibrated at fixed 100 Hz/1 kHz/10 kHz points only [S3].
Trackable signals: the Mastech commercial price list still lists MS6013 at US$41.45 and MS5308 at US$243.95 as of 2026, indicating a stable budget-to-mid-tier handheld market; IET Labs continues to ship the 7660 as the active replacement for the discontinued 7600 Plus, and the LCR-6000 family from Texio remains the widest 5-model benchtop lineup in the Japanese catalog [S3][S5][S9]. Suppliers to watch in 2026-2027 include the Indian distribution channel at Scientific (carrying a broad 20 Hz to 8.5 MHz filter range) and Chinese OEMs at OWON and Tonghui for cost-engineered benchtop units [S4][S6].
