This item is available to special order only, if you decide it is unsuitable for you needs it may NOT be returned. For the guarantee, see the GUARANTEE tab above, please check that you are happy with this before ordering.

Includes fitted case, U.K. power supply for mains

- reasonably accurate once you've got the 'knack' of interpreting the lights

- quite fast

- does not use an acid contact fluid

The price does not include a sample of 14ct (must be exactly 14ct, i.e. anything with a full British hallmark). If you are a dealer in scrap, you will have this - if not you will need both of these in order to use the machine, so please add "14ct calibration sample" to this order.

Typically, a test takes 2 or 3 seconds. Compare this with other testers (both acid-only and electronic) which are fiddly and can take over a minute per test. This DOES make a difference if you have 20 items to test and a queue of customers!

You do have to regularly calibrate the AGT1, but this takes less than 10 seconds, there is no other preparation (apart from filing the item). With other electronic gold testers, dispensing the acid / gel and testing is very slow, and cleaning up afterwards takes 2 or 3mns.

No acid involved (unlike chemical tests); no messy contact fluids of gel dispensers (which are always acid) unlike other electronic testers.

The probe lasts a few thousdand tests (the manufactureres say 5000, some of our customers say 2000) providing you replace the cap tightly when not in use.

Also tests platinum....but not always.

Each AGT1 is supplied with a case and a mains power supply (though it does also take batteries). IT DOES NOT INCLUDE A SAMPLE OF 14ct which you will need for calibration (otherwise the AGT1 will quickly become innacurate) - though if you are a scrap dealer, you will have this (do double-check that it has a Britsh hallmark).


As with all testers (including all other electronic gold testers) the item must be filed first, both to cut through any gold plating, and to remove surface contamination.

It's American so they use the abbreviation "K" for Karat rather than our "ct" for Carat, and they refer to 10ct rather than our 9ct. No great problem, just worth noting.

It does not test silver.

There is no acid, there are no export restrictions.




If the item develops a fault in the first year (even if that is in the first few days) we must return it to Gemoro in the USA for "evaluation and repair". We have been dealing with Gemorro for a few years: they ALWAYS say a repair will take a few days, it ALWAYS takes several weeks, without exception.

Returns out of guarantee -

After a year, if it breaks down, it is not economically viable to send it back to Gemorro for repair, they expect you to throw it away and buy another one. If you really want to try (and see wha happens!) we can give you their address.


The probe is a modified felt pen, it dries up easily if you leave the cap off or don't replace it firmly, and then you will have to buy a new probe. For this reason, the probes are not guaranteed. If you replace the cap between tests (push hard, until it clicks) it could last thousands of tests. Whether 'thousands' is 2000 or 5000 is open to debate. A new pen is not expensive, keep a spare in stock!
