Best Overall: DROK electronic component Tester

Buy on Amazon

The look and feel of this testers are consistent with the high quality we're used to from the rest of Drok's lineup. This multifunctional capacitance meter can be used to test triode, field. It's really handy, and helps keep the workspace clutter-free. It is good for testing transistors and caps and inductors. The tester automatically detects the device under test and provides textual as well as graphical display of device type, parameters, etc. It also is a quick way to read resistors, capacitors, and coils and display their value.

The tester will also check resistors, capacitors, and coils and display their value. They come in many pin sizes so be careful that you order the one with the same number of pins that the tester uses.

• Works great on unknown/unreadable transistors too for identifying the lead configuration
• Great for quick go-nogo checks on small discrete components
• Very easy to use and measures a multitude of transistors

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

Buy on Amazon

Der Ee Electrical Instrument has been making great tester for years, thanks to a combination of clever design and appropriate materials. It measures inductance from nanohenries to kilohenries with very good re-retest reliability. It measures down to the tenth of a picofarad in capacitance. It is valid for inductance, capacitance and resistance as well. It's also good as a bench model.

It is fully auto ranging operation for ac impedance & dc resistance measurement. It's extremely helpful for winding coils of a few nano Henries.

• Can measure capacitance at five different test frequencies
• Great tool to own for electronic hobbiest
• The highest test frequency supported by the de

Best For stuff: Ywnyt electronic component Tester

Buy on Amazon

If you often find yourself scrambling for appropriate and satisfactory tester, ywnyt electronic component tester should be your first option for buying. Being a great piece of test equipment, the TC1 is just plain fun to use. It is great for stuff less than 10v. The case, battery, and leads are enough to put it head and shoulders above the rest. The tester has a set of sockets for the devices, with a lever that releases and locks the component. It can set the battery voltage to be less than 4.5v, otherwise the tester may be damaged. This lever sticks out, and there's no way to put it into a safe position.

They give you two parts to play with and build your knowledge. It's not perfect, but it is very good, very cost effective, very portable and very capable.

• Can also press the multi-functional button to close the detector
• A must have for every electronic kit builder
• Great for hams and any component-level builder

Best For quick component testing: Aceirmc electronic component Tester

Buy on Amazon

Not everyone likes to purchase tester for their daily purpose, but the aceirmc electronic component tester would be an anomoly. This meter identifies which transistor lead is the base, collector and emitter. It works with NPN and PNP transistors which is nice. It can be in the correct order and the diode symbol displays two diodes, and gives the diode forward voltage. It even reads the value of air variable capacitors, just make sure the plates are fully meshed, and you will get the maximum value. It is pretty straight forward additionally it is great for a low cost tester.

The product runs on an Amtel microcontroller and is put together nicely. It is easy to use and makes a great teaching tool. It is good for testing items in-circuit.

• Highly recommended for any electronic repair person or hobbyist
• Great for a low cost tester
• More poking around with meter leads ascertaining readings

Best little Multifunction Tester: Sywan electronic component Tester

Buy on Amazon

Next on the list, we've got yet another tester that manages to win our hearts. It's the sywan electronic component tester and it's widely considered as tester that has the most suitable features. This is a super handy little gizmo. It is used to detect npn and pnp transistor, capacitor, resistor, diode, triode, n-channel and p-channel mosfet, igbt, jfet, triac and battery etc. It also does capacitors, diodes and resisters.

• Can also press the multi-functional button to close the detector
• Good investment for long term

Best For Basic component Tester: Aideepen electronic component Tester

Buy on Amazon

The aideepen electronic component tester should be able to handle its purpose and duties with ease. The Aideepen unit is solid. It allows the leads to be inserted "loose", and the lever does the clamping. Conversely, the aideepen tester has a rechargeable battery on-board. It displays the voltage of the battery on the screen. It works well on component testing.

This meter works well for identifying and measuring components. They offer the ability to KNOW exactly what you are installing in your projects, in a time when many companies play fast and loose with tolerances.

• Great value for a transistor tester
• Feels really wiggly, and very unprofessional
• Works fantastic, quick reads and easy to use

Best Easy To read: LCR research electronic component Tester

Buy on Amazon

The lcr research electronic component tester's high-end materials makes sure that it ages well with use. It is a high tech company founded by seasoned visionaries with real-world experience in hardware, software and business leadership. It is an all-in-one portable device that provides a simple and efficient solution for not only measuring smd components, but also making in-circuit debugging. It has all the great features that come with the lcr pro1, plus an additional led testing function and excellent sensitivity to measure very small inductance down to just a couple of nhs thanks to the ultra low noise design and 100khz testing frequency.

The ability to set excitation voltage to 0.2 V is great when working on mixed analog, digital circuits. It is specially designed for in-circuit debugging because it is low enough to prevent the silicon chips from being active during measurement. It is an ideal device for many applications including components verification and sorting, production lines, laboratory and service center, in-field repair and more. The tool also helps you to understand your circuits better.

• Accurate, usable, automatic lcr function is great
• Makes reverse engineering a circuit, a breeze
• Good display quality, super for component testing in dense surface mount environments
