ANALYZER (by Auracle)

Analyzer: summary

The ANALYZER has the same electronics as the Kee tester (the most reliable electronic gold  ever!). The ANALYZER features an LED meter instead of an analogue meter, and an LCD display with 'prompts' to help you with the instructions. 

• Tests gold from 8ct to 24ct. 
• Can be powered by mains in addition to battery  
• Low-battery indicator
• One-touch calibration
• Compared with previous models the pen-probe has finer tip, lasts longer and costs less 
• Carrying pouch included when you buy from Quicktest
• Gold-polishing cloth included when you buy from Quicktest
• Hallmark card included when you buy from Quicktest
• UK power supply for mains operation included when you buy from Quicktest

Analyzer: detail

It has the same electronics (microchip) as the KEE tester (the best-known and most reliable tester, discontinued in 2025). Instead of an analogue meter found on the KEE, the ANALYZER has a row of LED lights. This is a greatly improved version of the old AGT1 Deluxe (the manufacturers say, "20% more accurate") - the reading is instant and definite (no judgement involved). In addition to the row of LED lights (which tell you the carat) there is an LCD display that gives you instructions ('prompts').   

• As with every tester (whether you spend £100.00 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. 
• The pen-probe provides up to 6000 tests (then you buy a replacement pen-probe).
• As with every electronic tester (whether you spend £100.00 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. 
• Size 145 X 105 X 30mm (5.75 X 4 X 1.25 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)
  
• Simply touch pen probe to the item, result is shown in 2 or 3 seconds, very fast
  
• Easy one-touch calibration with a sample of 18ct - not included

It works best on yellow gold, they are unreliable on white gold, they are not suitable for testing platinum, steel, Palladium and silver - every serious scrap/bullion dealer keeps a set of acids (e.g. Troyest-4) for testing these.  Scroll to the bottom of this file to WHITE METALS to see what happens when you test these on an electronic gold tester. 

Important: 

• The tester will require calibrating regularly, you will need a calibration sample. This  is not included (because you probably already have some hallmarked 18ct - but if you don't have any please add an 18ct calibration sample from OPTIONAL EXTRAS. 
  
• We don't advertise this as being able to test for platinum because the 'platinum' reading is not reliable.

Analyzer: pros and cons

PROS

• TWO displays, one for the reading and one for instructions
• One-touch calibration, no need to turn a knob
• Only requires one calibration sample, not two 
• Low-battery indicator (and easy to change the battery)
• The pen-probe has a fine tip (easier to test very small items) and lasts longer and costs less than the old pen-probes.
  

CONS

• Old-fashioned in appearance, with the LED lights, not super-slick like the latest fully-digital models
• More sensitive than the Kee, the item has to be well-filed before testing
• The pen-probe must be primed* before you start testing, by carrying out two or three 'dummy' tests before taking the final reading. 
  
• The manufacturers incorrectly describe this as 'charging' the pen-probe rather than 'priming', which causes great confusion!

** To keep these testers working accurately you need to calibrate them against a known sample.

WHITE METALS

These testers are not for testing white metals. 

White gold with a high nickel content will give a reading that is too low; or if it contains Palladium or has a high silver content it will give a reading that is too high. You will not, of course, know if it is reading too high or too low, just be aware that the reading will not be accurate. 

Silver reads as not gold. We do not know of an electronic silver tester, if you find one, please let us know. 

Although there is a 'P' reading for Platinum, we don't advertise these as a platinum testers. Rhodium gives a platinum reading. Steel, tungsten and pure Palladium can read as platinum...or they can read anywhere from 18ct to 24ct.

In summary: do not use these testers on white metals.  Do not turn down jewellery made of white metal, make more money, get a Troyest-4.
