Gold Purity Tester
The Easy Way To Test Gold & Platinum Jewelry Measure the purity of rings, chains, watches and more… So now that you’ve found your fortune detecting – how much is it worth? That’s the potential dilemma facing every successful detectorist – you may know a friendly reputable jeweller who pays ‘top dollar’ for your treasure finds, or do you take your chances at the nearest unknown pawn shop?
While golden treasure may be instantly recognisable as soon as you uncover it, the gold karat purity rating could be anything from 9K to 24K and that dirty silver ring could even be platinum in disguise! With the PRO‑ALLOY gold tester there’s no messing around with dangerous acids or having to scrape away a portion of your find and potentially damage its intrinsic value. Just place your item on the test plate, touch it with the attached probe, and determine its gold purity from the easy-to-read scale. PRO-ALLOY is battery powered, so you can use it at home or take it detecting and cash in your finds on the way home!
Features: Instant gold karat reading Fast and accurate Non-destructive Protective case included Batteries included (1xAA)

Test Probe Replacement The test probe supplied with the PRO‑ALLOY is a consumable part that will need to be replaced. A new probe is only necessary after several months if it's used frequently, or if the probe cap is left loose or off. If the pen has reached the end of its useful life, the unit will most likely behave with similar symptoms of a low battery. While attempting to calibrate on 18K, you will not be able to adjust the needle up (or down) to the 18K mark. If you ever experiences this, try the following: Make sure that the 18K sample is absolutely clean. Change battery to a fresh one to see if the problem disappears. We recommend alkaline batteries as they hold a flatter and more consistent discharge curve. If the two above points do not fix the problem, check the probe for a dry tip or other irregularities.
Replacement Probe (Part No. 3011-0309) Replacement PRO- ALLOY cables (Part No. 3011-0310) and a Protective Meter Cover (Part No. 3011-0311) are available for individual sale.
