Summary

• 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 

INCLUDED, IF YOU BUY FROM QUICKTEST:

• Carrying pouch 
  
• Gold-polishing cloth
• Hallmark card
• UK power supply for mains operation

Technical

• 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)
• The pen-probe provides up to 5000 tests.
  
• 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 
  
• 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. 
  

Review

This has the same electronics (microchip) as the KEE tester (the best-known and most reliable tester which we sold between 2018 and late 2025). Instead of an analogue meter found on the KEE, the ANALYZER has a row of LED lights, so you can see how close to any standard carat (9ct, 14ct, 18ct, 22ct) the item is. 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!), and it also has has an LCD display that gives you instructions.  

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 model 
• 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!

OTHER METALS

The ANALYZER tester works best on yellow gold. Results on white gold are not so accurate. 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. 

Although there is a 'P' reading for Platinum (and the ANALYZER is is widely advertised as a 'gold and platinum tester') - we don't advertise it as a platinum tester - because it's not reliable. It does usually work if you file the item very thoroughly...but this is not reliable. 

Pure Palladium, steel and tungsten can read somewhere between 18ct an 24ct (be suspicious, 22ct+ gold because 22ct+ can only be yellow), but they can also read as platinum.  

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 (of whatever is underneath the rhodium) will be more accurate.

Silver reads as not gold.

You can test all of the above metals with the Troyest-4 acid tester.

CONCLUSION

As a reliable no-frills tester, it really is hard to beat this one.
