Two premium electronic gold testers from Tri Electronics
The built in microprocessor makes gold testing simple. Simply squeeze the special gel from the probe, press the button for the color of gold you are testing, and obtain the reading in karats and percent. Also reads "Platinum" and "Not Gold." These units test yellow, white, green, and red gold.
The GTXL18 is our most efficient gold tester for those testing 18 karat and below. Reads from 6 karat - 18 karat. 3 year manufacturer's warranty.
Uses gel product code GEL.
The GTXL24P is a highly recommended gold tester for those who regularly test gold above 18 karat. Measures from 6 karat - 24 karat. It comes with instructional DVD. 3 year manufacturer's warranty.
Uses gel product code GEL24I.
The GTXL18 is shown at right in image along with the economy model GT3000.
Portable Tri Electronics Gold Testers
Tri Electronics Pocket-Size Electronic Gold Testers
Using an ecologically safe liquid, Tri Electronics two new gold testers accurately test both yellow and white gold and give their results on an easy to read digital display. The GTP18 tests both yellow and white gold from 6 to 18 karats; the GTP24 tests yellow gold from 6 karat up to 24 karat and white gold from 6 karat to 18 karats. Both read "Not Gold" for anything below 6 karats. Both testers use the GTP-TL testing liquid; one bottle gives about 400 tests.
Both operate on 3 supplied AAA batteries or with an optional AC/DC adapter. The GTP24 is covered by a 2-year manufacturer's warranty; the GTP18 by a one-year warranty.
Model GTP24 is shown at left - the GTP18 is similar.

Acid Gold Testing Kits
Gold/Silver Acid Testing Instructions
-Leaves no scratches or stains on your gold after measurements
-Wide karat range—from 9 to 24K
-Tests other precious metals such as platinum and silver (SCGK2000 only)
-Also functions as a normal gram scale
-Available in 220 volt
“The acid test” is the traditional method of testing gold: if the gold is the same karat as or higher than the test acid, it will not react. If it does react, it is of a lesser karat than the test acid. The needles included in the test kits provide a standard for comparison. The acids are easily dispensed from plastic squeeze bottles. Available in wood or plastic box.
Acid gold testing kits include:
• Set of test needles - 8kt, 10kt, 12kt 14kt and 18kt gold, .999 silver-tipped needles and instructions;
• Top quality test stone (1¾" x 1¼" x 3/8";
• 10kt, 14kt, and 18kt acids in plastic, color coded squeeze bottles;
• Instructions.
Gold, silver, and platinum test acids; test needles; and test stones are also available separately.

Precious Metal and Gold Karat Testers
Quickly, easily and accurately determine purity of precious metals and gold karat by two weighings ( By measuring the Specific Gravity) : one with the piece in a water tank, the other normally. An internal computer does all the calculations for you. Works only for solid metal pieces without set stones.
-No acid, needles, or test stones needed -Leaves no scratches or stains on your gold after measurements
-Wide karat range—from 9 to 24K
-Tests other precious metals such as platinum and silver (SCGK2000 only)
-Also functions as a normal gram scale
-Available in 220 volt
**Advanced Model GK-2000 can measure up to 2,100g, which makes it possible to measure ingots and statues. Gold and Platinum measurement modes are available on GK-2000.**
