KEE Gold Tester

The instruction sheet really needs to be improved, very ambiguous - went on you tube to make sense of it, plenty of instruction videos. The item itself is excellent and very easy to use (now I know how). Very pleased. Looks robust hopefully it will do the job for years to come. Way better than using acid and appears to be very accurate when calibrated with 18ct gold. The fly lead also works well for testing off of the unit's table Worked on Platinum as well.

Very bad

Once you calibrate it with 18kt gold. It works great very easy to use and a nice addition to my business. I would recommend calibrating it each use, for accuracy.

This is one of two test methods I use for every single piece of gold I have – my first piece of advice would be to get a whole pile of stuff you know is not gold, but probably gold tone, maybe gold plated and possibly gold fill. Then get as much gold jewelry as you have, in addition to gold coins or whatever gold you've got that you know to be solid. MAKE SURE YOU CALIBRATE THIS CORRECTLY! Start testing with the probe properly plugged in – clean the desk/plate with a polishing cloth, and make sure the pieces you are testing are clean. Write down how the needle reacts when you apply the probe to the gold on top of the testing disc. Once you've gathered a substantial amount of notes on maybe 20 to 50 pieces? You'll have a great idea of how this tool works and what to expect when you're dealing with real gold or other – you'll know exactly what behaviors indicate what gold content or lack thereof. In most cases, it correctly registers 10 K versus 14 K versus 18 K, etc. However, it doesn't always do that – especially once your pro tip gets a bit dirty, which is why you need to clean the jewelry you test. I use this first, then drill down with an acid scratch test to determine the exact gold karat purity. (10k, then 12k, then 14k, then 18k, and so on. Without a $10,000 XRF machine, don't expect the wonderful little tool known as the KEE gold tester to be your oracle. It's 300 bucks and well worth money. For what it does. critical final note: ALWAYS, always, always Replace the cap on the probe as soon as you're done with it. Once it dries out, it will not work anymore and you'll need to replace it. The probes are not cheap. If you need a relatively inexpensive tool? Buy this, and make sure you don't end up replacing the probe because you'll end up spending about a grand within a year. Try calling your local jeweler to see if they've got one and would be willing to calibrate yours for you especially if you don't have an 18 carat disc or can't afford to buy one. You'll need one for calibration and you can't skip that step.
