Summary In stock and available for immediate dispatch (unlike other suppliers, we don't take your money then order it from overseas!).  Includes pen-probe. Making it with a simple analogue meter seems to have solved the problems found with 'computerised' electronic gold testers. This is definitely the most reliable electronic tester we have seen. The price does not include a sample of 18ct and 22ct.  If you deal in jewellery you will have these - if not, you will need the 18ct sample for testing general jewellery; plus the 22ct sample if you want to test above 18ct accurately. Guarantee: 1 year Detail Size 90 X 170 X 50mm (3.5 X 7 X 2 inches) No acids involved, the probe contains a harmless salt solution. Tests gold from 8ct to 24ct (the scale is marked "K" instead of "ct" because it's American) The pen-probe provides up to 3000 tests. Simple analogue meter, good reliability Simply touch pen probe to the item, result is shown in 2 or 3 seconds, very fast Includes extra contact leads for large items that will not fit on the test-plate. Easy calibration with a sample of 18ct (+ a sample of 22ct gold if you want to test above 18ct accurately) - not included in the price of the tester As with every tester (whether you spend £15.00 or £12,000.00) it only tests the surface. This means you must file the surface with a fine needle-file (supplied with each tester) in a place where it won't show, to remove any surface plating.  INCLUDED: Battery Diamond-impregnated file Very clear illustrated instruction booklet written by QUICKTEST An extra set of leads for testing very large items that will not fit on the test-plate (though we have never known anyone who has needed to use these). White Metals  SUMMARY The KEE tester works best on yellow gold.  On white gold It will (providing the item is filed thoroughly) tell you if it is gold but will not necessarily give an accurate carat reading; it will also (providing the item is filed thoroughly) tell you if it is platinum.  DETAIL Silver reads as not gold. Steel or tungsten can read as high-carat or as platinum if it is not filed first; once filed it should read not gold. White gold with a high nickel content will give a reading that is too low; white gold containing Palladium, or with a high silver content, will give a reading that is too high. Pure Palladium will read somewhere between 18ct an 24ct (be suspicious, 22ct+ gold an only be yellow). Rhodium is used as a plating to improve the colour of the gold. If you don’t file it, it will test as platinum; if you file it slightly, the tester will pick up both rhodium and gold and the reading will be too high; if you file it thoroughly, the test will be more accurate. Extras Also included, the following free gifts (these don't come as 'standard'): Carrying pouch  Mini hallmark chart  Gold-polishing cloth and you will have the option of selecting a free gift! (online orders only).  OPTIONAL EXTRAS: A pen-probe is included, if you want a spare, select it from "Optional Extras". To test 9ct to 22ct you will need a sample of 18ct yellow gold (it must be exactly 18ct). This is to 'match' the electronics in the tester to the carat (technical term: calibrate). You cannot use the tester without this. If you want to test 20ct to 24ct accurately you will also need a sample of exactly 22ct. You can use anything with a UK hallmark or you can add one (or both) calibration samples to your order, click on View Optional Extras. UK traders will already have hallmarked items, which is why we don't include the calibration samples in the price of the tester. Reliability The tester is guaranteed for one year. the level of returns is 2%, of which half turn out not be faulty at all (used-up probe, flat battery, out of calibration).  we do find that many are faulty when we receive them from the supplier in the USA.  We return these to the supplier, we do not sell them. Unlike other companies, we open and test every one thoroughly  That's why we have such a low level or returns; that's why we have such good feedback.  Pen-probe  A pen-probe is included with your purchase, if you want a spare, click on View Optional Extras. A pen-probe is guaranteed for one month. The pen-probe is like a felt pen, if you don't replace the cap firmly it dries out. The manufacturers say it will give "up to a few thousand tests" (which could mean any number less than this). They also say it should be replaced after a year (a year from the date on its sticker). Comments from customers:  The KEE tests on average about 40 items a day and  the probe lasts about 6 months, 5000 tests. The solution in the probe outlasts the tip which becomes soiled from testing scrap. We replace the probe when reliability drifts and more regular calibration is required with our 18ct control sample. We get around 3 months and test around 10 times a day, often 15 times a day. Overall we think they last well.  Our probe only

Replacing an existing one of these which lasted years. Very easy to use, and reliable. Pens wear out over time, so worth getting a spare. Quicktest service as usual was excellent - very fast delivery
