The 6 Best Digital component testers (2023 reviews)

The drok digital component tester should be able to handle its purpose and duties with ease. For testing transistors or diodes, this device makes segregating similar performers together, much simpler. The schematic representation and precise readings are useful for parts that have worn off and do not show markings like old caps and multicolored LED's. They come in many pin sizes so be careful that you order the one with the same number of pins that the tester uses. This is a very nice all in one tester and appears to be prey accurate.

The unit doesn't have a 4th input and just 3 in different arrangements to support different ordered pinouts without having to bend the leads on the device being tested. It helps to buy a pack of inductors of various values to always check the tester. The tester will also check resistors, capacitors, and coils and display their value.

Why We Like This:

Great little device for simple readings of transistors and other semiconductors
Extremely useful and affordable tool for testing electronic components
Simply and automatically measures inductors, capacitors, resistors, and identifies transistor type and pinout
Handy portable and easy to use component tester

Best For surface mount components: DER EE electrical instrument Digital component Tester

Buy on Amazon

Next on the list, we've got yet another tester that manages to win our hearts. It's the der ee electrical instrument digital component tester and it's widely considered as tester that has the most suitable features. This instrument is very precise inherently, by having a very high input impedance. It powers up and measures a couple of resistors and a capacitor just fine. It has an optional optical-usb adapter (called optical usb-case attached to the back of this meter) for connecting to your computer. The buttons are easy to read and the LCD is what LCDs are. The second attachment offers alligator clips to help connect to larger components that the tweezers cannot address.

This is a versatile, accurate, dependable and affordable LCR meter.

Why We Like This:

Great tool to own for electronic hobbiest
Accurate and great value for money
Excellent little unit for making milliohm measurements

Best For identifying quite A few different types of components: Aitrip Digital component Tester

Buy on Amazon

The aitrip digital component tester is capable of outshining several other tester featured in this list in overall features for the price point. This tool is seriously a miracle, and excellent value. It can measure two resistors simultaneously. It offers an interesting challenge in case assembly and device use since there are no instructions with the device. The tester displayed two diodes with opposite polarity and the voltage drop for each. It does an excellent job of reporting their capacitance value and esr value.

The accuracy is very good on this unit. The convenience of being able to quickly just plug in a part and 2 seconds later it automatically tells you exactly what it is, really makes life simple.

Why We Like This:

Very accurate and inexpensive capacitance and esr meter
Lot of satisfied buyers

Best component Tester: Aideepen Digital component Tester

Buy on Amazon

The aideepen digital component tester's high-end materials makes sure that it ages well with use. This tester is very handy in performing quick component testing. It works well for general testing of electronic components. It is used to test triode, field-effect tube(fet), diode, resistor, capacitor, inductor, mos, scr, which is available for various electric transistor testing. It is very useful and a great value but be sure to make sure capacitors are fully discharged before hooking this baby up because it doesn't take much to fry it.

This tester is extremely versatile and can help identify and measure so many components. It is a great piece of test equipment.

Why We Like This:

Come in handy for quick test of off the shelf components
Saves so much time and effort
Delivered faster than by "slow boat",works well for general testing of electronic components
An excellent tool to identify and measure components

Best For small value capacitors: H Holdpeak Digital component Tester

Buy on Amazon

The h holdpeak digital component tester is suitable and reliable and fits well with your daily purpose. It comes with the function of the continuity and diode test, you can use it for many applications, such as components verification and sorting, production lines, laboratory and service center, in-field repair,battery power test and more. The gold-plated test tips meet squarely and won't "flip" or "fumble" components when you apply gentle pressure. It even has a place to store the batteries with the unit when not in use for longer periods.

When set in the diode test mode, this tester will illuminate LEDS. It compares very favorably to any other 6000 count DVM. There is a slide switch toward the probes that can be switch to diodes to provide the necessary voltage/current to illuminate the LED to indicate the actual color as well as the current reading. It's the added bonus of a very well made storage case to protect the unit.

Why We Like This:

Extra test wires are also useful
Gold-plated test pins, which can induce its contact resistance and prevent it from rusting
Good brand reputation

Best SMD Type: unit Digital component Tester

Buy on Amazon

The unit digital component tester should be able to handle its purpose and duties with ease. This meter from UNI is really great for testing discrete components in circuit. It is perfect solution to classification and detection of discrete chip components, debugging, maintenance of complex electronic systems. It is so handy to have around, for components on and off the pcb, especially resistors and batteries.

This is one of those tools that is great to have in your collection of testing tools. The tester is fairly small measuring only 8" overall. The device is top heavy, so its kind of hard to work with if you have small hands. There is also an extra set of spare tips mounted to the cover. This is an interesting test meter that lets you get into a dense surface mounted board to check voltages and continuity.

Good investment for long term
One of the new comers and featured product
