Best Electronic Gold Tester Reviews: Gold, gold, gold… It is a very precious element found deep inside the Earth. It is slightly reddish-golden, bright and delicate yet dense, and feels premium when in its most genuine form. For everyday use, pure gold is too soft to be worn. Therefore, it is alloyed with other base metals like copper, silver, nickel zinc, etc. This gives gold the needed durability. As a standard measure of its purity, ‘Karat’ (k) is the recognized symbol. Best gold testers can help you ensure its quality.
24k gold is the most expensive one being 99.9 percent pure. Mostly, it is not used for making jewelry and 22k gold is used for the same. It has 22 parts gold and the other two are base metals making it a lot harder. 18k, on the other hand, is 75% gold and 25% other metals. This is more appropriate for bejeweling diamonds and other stones. Gold is oh-so-valuable, thus, testing for its purity comes along. No matter the reason, gold testing techniques have been around for ages.
However, with the advancement of technology, such methods have increased. Today, we have electronic/ digital gold tester pens and instruments that prove valuable and help evaluate certified gold. So, here we’ll take a look at the best gold testers for sale on Amazon. I’ll tell you how the most accurate gold testers work, what are the advantages, and also share the best gold tester reviews for 2024.

What Are Electronic Gold Testers?
Acid tests are quite popular when it comes to gold testing. The best gold testing kits are brought to use for observing the resultant reactions. The scratch or touchstone test is another method of identifying the varying colors of the gold to find the genuine one. Since the advent of electronic gold testers, things have become easier. Nitric and hydrochloric acids are potentially dangerous to work with. One needs proper expertise as well as safety gear such as gloves and glasses. These aren’t travel-friendly, especially while shipping or by air. An electronic gold tester, however, differs in design and implementation. It is hassle-free and doesn’t involve any hazards. Although these too use some sort of gel or custom-made liquid. But, the level of risk is significantly reduced.
Tri Electronics and GemOro are popular US brands that manufacture such gold testers. These are less risky than household chemicals or other testing methods that have been around for some time now. Their testing units are compact along with being pretty affordable.
Such brands bring to you professional-grade instruments that can test a larger number of items daily. Mostly there are two types of gold testers available in the market – ones that can test up to 18k of gold purity whereas the others can test up to 24k gold. The former is a less expensive variant and the latter remains to be on the costlier side. 18K testers are generally less sensitive as compared to other advanced models. Therefore, there also are more chances for mistakes. So, testing coins, for example, would require a 24K electronic gold tester than any other to omit errors and give out precise readings. Such unconventional models are more sensitive as well as accurate. Let me now tell you how electronic gold testers work …
How Do Electronic Gold Testers Work?
The best gold testers out there help you gain some vital information. Gold, platinum as well as other such precious metals are measured to determine whether they are genuine or not. Based on an element’s electrical conductivity, authenticity can be obtained with a digital gold tester.
In professional terms, an electronic gold tester measures the decay of electrical current passing through it. You clean the piece in such a way that one spot remains on the testing board and the other side remains on the top so the sensor can test. A probe pen has some kind of non-toxic gel that releases onto the sample that is being tested. The battery current then passes through it to finally give the exact reading – in other words, the Karat reading. There’s no destruction or any kind of marking left while testing and the process is environment-friendly as well as safe even if you have kids around as opposed to acid testing.
Advantages Of Having A Gold Tester…
Counterfeiting is a serious scam for both jewelers as well as customers. However, an electronic gold tester can help you prevent the risk of that too without having to destroy the item. These devices are an innovative solution to ensure high-quality and precise testing of gold, platinum, silver, and other such metals. So basically, an electronic gold tester is a licensed as well as quality-controlled compact device that helps you test the genuineness of gold. It unconventionally helps test the purity of gold – no use of acids, filing or scratching. You can simply touch and test. (Check out the best gold tester reviews to choose the right device for yourself).
Gold testers for sale are lightweight and travel-friendly. The apparatus comes with a testing pen. LED indication bars, LCDs, or needles tell you the exact values in terms of karat along with other vital information. Once you put in the batteries and the device turns on, you will then have to calibrate the same before testing the final pieces. When the preliminary steps are taken care of, start testing without any trouble. You need no expertise in carrying out the test. Just go through the manuals and the device will show accurate results.

How To Use Electronic Gold Testers?
Gold testers are incredibly easy and quick to use. It’s a mess-free process and most of the testers display measurements in karats or gold colors. Not just gold, these kinds of gold testers for sale are efficient enough to even test silver, platinum, and other such metals. You can follow the instructions manual that comes along. But, if that’s not your thing, here I’ll simplify the steps. So, how to use electronic gold testers?
This Is How: You Can Use Electronic Gold Testers
Put in the required batteries for the unit to power on or you can also separately purchase and use an AC adapter. Switch on the battery setting when using that or switch to the adapter setting when the cord is plugged in. Quite easy to start with. (Keep in mind that I am referring to models like the GemOroAuRACLE for this explanation).
Next up, plug in the testing probe and run the calibrated device to maintain accuracy each time you want to test a metal in the future. Switch on the equipment, get a sample piece of gold (preferably or at least 14k), and place it on the testing pad. Remove the cap of the testing probe or pen, touch it to the item (not too hard, not soft), and wait for the light indicator on the LED bar to start ascending. Once it starts to move upwards, wait until it gets to a steady point somewhere in the middle. When the light blinks steadily, press the ‘Calibration’ button and hold on for a few seconds till you see a green light that indicates the machine is ready to test.
After calibrating, the final step now is to test any other piece of gold which is the procedure you carried out during the calibration process. However, now you can test for samples that you don’t know about. You also get a filer with some models to file the piece a little and get a cleaner surface for testing. However, it’s practically not recommended to do so with high-value pieces or jewelry since you may damage or heavily scratch the piece. But, it is totally up to you if there’s something you might want to test that way.
Anyway, just clean the piece yourself with tissue paper or just a regular paper eraser. Put it on the testing pad, take out your gold tester pen, touch the piece with it, and watch out for the LED indication to see how much karat gold it is.
An Example…
The above procedure is for testing gold items. So now for instance, if you have a platinum ring, the LED blinks on the PT (platinum) section of the same LED panel. A digital gold tester like the AuRACLE model by GemOre glows up the NA indication light if you test metals like silver, steel, or iron. NA means the metal isn’t gold. A metal like gold isn’t too light and feels dense when picked up as compared to other base metals. Put your common sense to the test and check for markings and other things. If you’re suspicious of an item, examine it further.
Once you are done testing with your electronic gold tester pen, make sure to put back the cap so it doesn’t dry up. Wipe off the tip of the device if you feel they are dirty – just use a paper towel and you are good to go. Some probe pens offer up to 5000 tests and once you’re done with that, you can easily purchase a new one.
In short, the conductor fluid of the probe pen reaches the gold item and applies the charge to indicate whether it’s gold (10K, 14K, 18K, etc.) or not. Check out our best gold tester reviews to find out which one to go for!
