Features
- High Accuracy LCR Meter - High accuracy measurement of capacitance, resistance, and inductance, it is a special digital instrument which is easy to be operated, the reading accuracydegree is higher with liquid crystal display 3 1/2
- Digital Multimeter Design - (Inductance) Measuring accuracy up to (2%+5); (Capacitance) Measuring accuracy up to (2%+5). Forward voltage drop of diode:Displaty forward voltage drop of diode; Forward voltage of DC:Approx.1mA; Reverse DC voltage: 2.8V
- Rotable LCD Display - Multi angle adjustment for easy reading. No need to hold tester while measuring, more convenient operation. Data hold function helps users to freeze readings on the screen, for convenient recording and analysis of data readings
- Easy to Use - Lightweight and compact ; Auto power off; Data Hold function; Low Power Indication; ZERO ADJ for Capacitance
- New Version Test Leads - Comes with crocodile clip/ Test Loads/ mini Alligator Clip; The black pen is connected to the negative pole and the red test lead is connected to the positive pole
- Why a Dedicated LCR Meter? Beyond Standard Multimeters Standard multimeters struggle with accurate inductance readings and low-value capacitance. The Proster LCR meter is purpose-built for inductance (L), capacitance (C), and resistance (R) measurements. With 3 1/2 digit LCD (1999 max count) and dual-slope A/D conversion, it delivers reliable readings for component testing, sorting, and troubleshooting
- Complete Kit Ready to Use Out of the Box Includes: LCR meter, test leads, crocodile clips, mini screwdriver, 9V battery, user manual, and a portable storage bag. Features data hold, auto power off, and operates on a standard 9V battery. Sampling rate of 3 times per second provides responsive readings. Backed by a 18-months quality guarantee
- Wide Capacitance Range 200pF to 2000F Measure everything from small ceramic discs to large electrolytic capacitors. 8 capacitance ranges: 200pF (0.1pF resolution, 2.5%), 2nF, 20nF, 200nF, 2F, 20F, 200F, and 2000F (1F resolution, 5.0%). Perfect for identifying unmarked caps, matching pairs, or checking for drift and ESR-related degradation
- Inductance Measurement 200H to 20H Easily test inductors, chokes, transformers, and solenoid coils. 6 inductance ranges: 200H (0.1H resolution, 3.0%), 2mH, 20mH, 200mH, 2H, and 20H (10mH resolution, 5.0%). Essential for winding your own coils, repairing switch-mode power supplies, or testing crossover network components

Fairly accurate for hobby work. Nice price for its extended capabilities. The zeroing function is limited and under given instructions it is best to touch both test leads or clips when measuring and write down the reading for subtraction to the measurement of the component. The hold function does work, but I've never used it in component testing with a LCR meter, only on live circuits. Mine did not come with battery so be prepared to obtain a 9v battery. The plastic surround shell can be easily removed if it's bright color is annoying. All in all it has plenty of testing options and a zippered storage that most higher priced units don't have. The display can be set to various angles but does not lock until back in horizontal position.

I've always wanted an LCR meter! It works amazing! Very quick readings, well within tolerance of known good capacitors, inductors and resisters tested. The only thing that would improve it, is a side pocket on the case to put the probes in when not in use. Minor, really, but a great meter!

Does a good job for the price. The insulated alligator clips are nearly useless because they can't attached to the probes. You can see inside that there isn't the usual socket that snaps onto the probe end. It's only the crimp for strain relief on the alligator clip is crushed flat to make contact with. All you can do is insert the probe and hope to make contact rather than attaching the probes so they can hang off a test point. The short probe for capacitance readings is decent but its leads carry too much capacitance to zero out. For small pF caps, I adjusted the probe capacitance to a nice number to make it easier to mentally subtract the value to get the actual reading. The values I read for parts were accurate enough to know if the capacitor under test was reasonably close to reading the indended value.

Works as it should. Easy to use. Great for testing old parts to salvage. A speaker builder must!

Very happy with this meter for the price. I verified the readings with some standards and it is very close. I wanted it because of the adjustable screen but found it worked so well for the price it is on my work bench now.

Good tool. Only concern is last one I bought in 2018 was dead in Aug 25 and in 7 years was not used very often. Properly stored, etc Hope this one last longer.
