## Overview

The FNIRSI LCR-P1 is a compact, rechargeable transistor and component tester with ±5% measurement accuracy. Featuring a 1.44-inch full-color display, Type-C charging, and intelligent auto-identification, it supports a wide range of components including transistors, capacitors, resistors, inductors, and batteries. Its anti-burn protection and NEC infrared protocol analysis make it an essential tool for electronics professionals and enthusiasts aiming for precision and safety.

## Description

FNIRSI LCR-P1 Transistor TesterFNIRSI LCR-P1 transistor tester can be used for the measurement and analysis of NPN, PNP, triode, MOS, field effect transistor (FET), diode, Zener diode, capacitor, resistor, inductor, battery, etc.FNIRSI LCR-P1 transistor detector supports the analysis of NEC infrared protocol code, so it can be used for the debugging and maintenance of remote control equipment.1.44 inch full -color screen, clearly visible, 300 mah battery, Type-c interface for charging and data transmission, firmware upgrade.The capacitance resistance esr tester automatically identifies undischarged capacitors and automatically discharges them at the moment of insertion and locking, effectively avoiding accidental burning.

Review: Transistor FET tester - Nice tool works well, quality item nice finish and rechargeable, also flying in Leeds and little PCB thank you very much
Review: Great gadget, especially if you're a newbie to the electronics world like me?. - As someone who's still learning everyday, this is a very useful little gadget. I wouldn't say I'm anything close to competent but I have managed to fix a couple of graphics cards and another board. This has been very useful as I've had to take components of other broken things. But not knowing what the capacitors and the resistors at the 0402 size are due to their very tiny size. This has been immensely useful. Now that said, it does have a lot of issues picking up 0402 resistors. You have to try multiple times with a few different things such as mosfets Dr. It can take a few tries to get the right reading. But even if all it did was tell me the capacitors that pays for itself so 5/5.

### ⭐⭐⭐⭐⭐ Transistor FET tester

### ⭐⭐⭐ Good but fragile.
*by P***L on 28 October 2025*

This is a premium tester let down by the fragile ZIF socket which suffered a snapped lever after a couple of uses, fortunately I had spare ZIF sockets on hand to solder a new one in its place. A friend of mine had a similar issue with this so bear this in mind if you want one.
