Proster LCR Meter - Capacitance Resistance Inductance Digital LCR Multimeter with LCD Over-Range Display

Works like a Charm, great value for testing Caps and Inductors.

Pleased with the performance as well as the included probes and carry case. Nice unit

Thieves broke in and stole some of my tools, including my capacitance meter. I opted to replace it rather than give up on fixing things. This is better than the pure capacitance-only meter I had, and it costs a little less than half as much. One of the big failure points with personal computers – both motherboards and laptops – is that the filter and isolation capacitors age and slowly lose capacitance. This meter can at least confirm your suspicions once you destructively remove the capacitor from the circuit. The only way I know to check them in-circuit is by using a magnetometer to measure in-rush current when you turn on the power supply. I have done that, but it is tricky, because you have to pay close attention to orient the magnetometer probe so that it is affected by the magnetic field produced by the current of the device under test, and also oriented so that it is aligned with the 3d null of the geomagnetic field at your geographic location. You end up kind of inconveniently bringing the system under test to the static geomagnetically-nulled probe rather than the convenience of bringing the probe to the system under test. Still, if you have 50 isolation & filter capacitors in parallel (like in a Tek scope), the inconvenience of holding the motherboard up to the probe can be less inconvenient than desoldering 50 caps to find out which one is open-circuited. In the unlikely event that a cap shorts-out, you can see the mag field produced by the current being drawn through the shorted cap anytime the power is on. But this meter is a good candidate for runner-up to a high precision magnetometer. And hit-and-miss desoldering is what everyone has been doing for over a century. Why work smart when you can work traditional with a cheaper tool?

So, I use this for my ham radio hobby, to build antennas, and to check the value of coils. I have a slew of text equipment ranging from the Super Mighty Harbor Freight free Red Multimeters that they used give away with a purchase to some of the better gear like my Fluke 87V, Fluke 77IV, Hitachi high end analogue oscilloscopes, etc. This thing for 30 dollars or so ( January 2026 ) is a miracle. The resistor values were spot on with my Fluke 87V. The fact is this is an LCR meter, not just a unit to measure capacitors, resistors, voltages, etc.. Even the included case is decent. The leads are not silicone, but still very flexible. I replaced them with Promasters, not that it was necessary. I am fussy about the quality of my leads and prefer Promaster and Fluke. Yeah, it costs more, but hey, why have a great meter and compromised leads. I've even swapped out my Simpson Model 260 and Model 262 leads for Promasters. So buy this thing and maybe consider upgrading the leads. The existing leads had a resistance of only 0.8 ohms which was more than half decent. They just were not as comfortable or as flexible as I like. I still give this unit FIVE stars

First off...I very seldom feel compelled to write a review. As the headline says, be realistic. This is not a 4 or 500 dollar piece of test equipment, so it can't be expected to have all of the quality, and functions of a higher priced item. My first impression when I opened the package was jeez, this is one nice looking meter. Then I started pulling out all of the accessories that came with the meter. There were several different models of test leads included that will allow the testing of many different types of circuits and components. The meter also has a quality feel to it that's close to the feel of my Fluke. How long the meter will last remains to be seen, but first impression is this is not a cheaply made piece of junk. I've seen many meters of different types over the years that were made in China, and yes most were cheap junk that usually failed in short order and looked and felt like they would break if you looked at them to hard. I must say that this products quality was a pleasant surprise. IMO, at the price point of this meter, it's a no brainer for those looking for an inexpensive tester for home projects.

surprisingly this is a very accurate LCR multimeter, covers the majority of the ranges needed for testing PCB components. and for the price it's definitely a good bargain!

Nice little meter has a lot of probes for versatility used the probes with multimeter to measure current. Thank you for the product.

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.

Es preciso acorde a su precio, las puntas con las que viene el producto si afectan la inductancia medida y el offset zero no balancea suficiente la medicion, recomiendo usar los caimanes mas cortos para una medicion de bajas inductancias mas precisa. Las mediciones de capacitancia y resistencia son excelentes.

This is a very unique, useful tool for those constructing discrete electronic component projects. My experience, so far, is that it does what it says it does, ie., measure LCR components. It is easy to use and comes with the probes and a carrying case making an ideal product. I have wanted this kind of device for fifty years and now I have it in a easy to use economical package. Kudos to the manufacturer.

accurate meter.

低価格でも、そこそこ趣味レベルで使える印象です。2005年ごろにもらったおまけの電波時計の時刻調整機能が悪くなり、時計電波同調用のLC回路を調べてみたくて購入しました。時計のコイルとコンデンサの並列回路のコイルのインダクタンスを測定したところ3.15ｍH、コンデンサは2.2ｎFで計算すると60.45KHｚでした。60KHzほぼぴったりで少しびっくり。また別途、手持ちのフィルムコンデンサも部品記載の値と合っていましたのでなかなか使えると思います。この製品が普通に耐久性があることを期待します。

Nice product for its price. Although measurements for capacitance and high valued resistors is not accurate, you get what you pay for.
