Product description

DROK Electronic Component Tester

Parameters:
-- Voltage supply: DC 9V Battery 6F22 (NOT Included)
-- Transistors range: 2 or less (including 2) P-N junction transistor
-- Resistors range: 0.5Ω - 50MΩ
-- Capacitors range: 25pF-100000uF
-- Inductors range: 0.01mH - 20H
-- Dimensions: 70mm × 135mm × 24mm

Operating Instruction:
>> The pins of the electronic components can be connected to the 1,2,3 pin optionally. This multifunctional meter is automatic identification type,
which can detect the pin sequence, graphic display and parameters automatically.
>> Eg. If you want to test a triode, you do not need to worry about the BEC order of 1,2,3 pin.
You just insert the triode into the testing interface optionally and then push the testing
button. The meter will identify it if it is triode, field-effect tube, controlled silicon or resistance capacitance.
After that, the tester will detect it if it is NPN OR PNP and then the BCE order and other information.

Testing Range:
▶ Range of Transistor: Less than 2 (included 2) transistor which is made up of PN junction. Do not have any other resistance components in the interior.
▶ Range of Resistance Testing: 0.5Ω-50MΩ
▶ Range of Inductance Testing: 0.01mH-20H
▶ Range of Capacitance Testing: 25pf - 100000uF

Package includes:
1× Multifunction Transistor Tester

Brilliant bit of bench testgear
Reviewed in Australia on 30 March 2021
Verified Purchase
This inexpensive and very portable test set can handle all manner of diodes and transistors, detecting type and pinouts on a colour screen. It can also accurately measure resistors and capacitors and reports ESR.
The items can be inserted anywhere in the ZIF socket provided. It would have earned a fifth star if the ZIF socket could be mounted in a more stable fashion, but this is overcome with careful handling. Highly recommended - a very useful item for identifying and measuring all the usual single components.

Very accurate measuring instrument
Reviewed in the United States on 5 December 2017
Verified Purchase
Product arrived as scheduled. Packaging was very sufficient as to prevent possible shipping damage. Installed fresh 9 volt battery, powered unit on and immediately began testing components. Upon power up, cool little logo appears onscreen and software boots up quickly. Tested and correctly identified approximately 40 capacitors in under half an hour. Color resolution is very clear. Tester showed very accurate identification for all capacitors I tested in uF, nF and pF values. Had a couple of 5k, 10k and one 20k resistor to check and the software quickly and correctly identified each one. Have not used for diodes, bridges or any other component as of yet, but am sure the same satisfactory results will be offered. Thanks.

Limit of 1 mV accuracy for transistor Vbe testing
Reviewed in the United States on 29 March 2018
Verified Purchase
I've tried this so far with BJT transistors and capacitors, and so far it seems to do a good job with both. The unit comes with no instructions, but couldn't be easier to use... plug each lead of the component into the ZIF socket, and press test. It's pretty magical actually to see the pinout and the component type automatically identified. In the case of a transistor, it will also show you the Hfe and Vbe... indeed, I bought this primarily for transistor matching and binning. A limitation here is that the unit's Vbe reading only goes down to the millivolt level, whereas demanding Vbe matching applications might demand 100 microvolts or even better. Nevertheless, I still think this is a win.. for getting really well matched resistors, the easiest approach is to use one of the simple breadboard rigs that you can find online that compares a test transistor to a reference transistor. This unit will let you do some easy prescreening for that workflow.. i.e. you can pre-identify the most promising reference transistor with respect to Hfe, and you will then also have a much smaller pool of candidate matches to screen (presuming you start with a pool that are already matched at the mV level). Two other factors lead me to knock of a star -- my unit arrived with a cosmetic scratch across the screen and faceplate. Also, unlike some of the other units out there, this one has no contact pad that will allow you to directly test SMD units, if that is important to you.

Works, but quality could be improved.
Reviewed in the United States on 8 December 2019

It works okay but has some issues. For a start, if your 9V battery gets a bit low it doesn't show warnings, it just stops working, turning itself off.

The little green insertion socket has a bump in the middle of the back, making it rock when plugged in. I filed that down so it will sit flush, but even then it sits above the case at either end so inserting or removing components to test also causes rocking. I expect it will break eventually. If the manufacturer improved the fit that would be nice. The green socket also has another problem: when the lever is upright there is nothing but friction holding it in place and it can work its way toward falling out as you use it.

There's no brightness control for the display to help save battery life (IMO it's unnecessarily bright). I opened it up and there is no trim pot for this either.

I don't read chinese, but there appears to be a warranty sticker over one of the screw holes on the case. These aren't legally enforcable in the US. It would be nicer to not see this kind of thing.

So overall decent enough and useful, but it would be easy for some small improvements to be made that I think would substantially increase the quality of this device.

A must have for any electronic test bench
Reviewed in the United States on 7 June 2017

There are other similar testers out there, but this one is unique in that it is mounted in a case and has a color LCD display. The versatility of this tester has replaced several other pieces of outdated test equipment on my bench. Besides providing nearly instantaneous accurate measurements this tester also identifies unknown components. It doesn't come with instructions but it's pretty easy to use: just plug your component into terminals 1-3 or 4-6 and the tester will figure it out.
