Auracle electronic gold tester, model PRO

Summary

This is the top model of the Auracle brand: the PRO (professional) gold tester. For the professional dealing with several thousand pounds-worth of gold per day, this is not expensive, just go for the best!

Two modes, standard and enhanced. 

• Standard mode shows the nearest 'standard' carat: 8K or 10K (because it's American), 14K, 18K, 22K or 24K. 
  
• Enhanced mode shows the proportion of gold, eg .750 for 750 parts per thousand (=75% gold = 18ct). This mode also shows a graph indicating how close the reading is to the standard carat. 

Guarantee: 1 year

Detail

• 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)
• 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 
  
• Works on battery or mains, mains adaptor (power supply) 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. 
  

Extras

Also included, the following free gifts (these don't come as 'standard'):

• Carrying pouch

and you will have the option of selecting a free gift! (online orders only). 

OPTIONAL EXTRAS:

A pen-probe is included, if you want a spare, select it from "Optional Extras".

You will need a sample of 18ct yellow gold (it must be exactly 18ct). This is to 'match' the electronics in the tester reading on the display (technical term: calibration).  Anything made of 18ct yellow gold will do, just check carefully that it has a British hallmark, then you will know it's exactly 18ct.  If you are a trader, go through your scrap / jewellery, you are certain to have some 18ct hallmarked yellow gold. If not, an 18ct calibration sample is available from us, see OPTIONAL EXTRAS.

Reliability

The tester is guaranteed for one year.

• new item as of late 2025, we do need to be selling these for a few months to get feedback (we do tell you which items are reliable and which are not!) - that it has the same electronics as the famous KEE tester (now discontinued) is a good sign, since the KEE was the most reliable tester we have ever sld. 
  

Pen-probe 

A pen-probe is included with your purchase, if you want a spare, click on View Optional Extras. A pen-probe is guaranteed for one month.

The pen-probe is like a felt pen, if you don't replace the cap firmly it dries out. The manufacturers say it will give "up to a 5000 tests" (which could mean any number less than this). They also say it should be replaced after a year (a year from the date on its sticker).

The following comments are from customers regarding the old (KEE) pen-probe, they say that this (Auracle Pro) pen-probe lasts much longer : 

• Tests on average about 40 items a day and  the probe lasts about 6 months, 5000 tests. The solution in the probe outlasts the tip which becomes soiled from testing scrap. We replace the probe when reliability drifts and more regular calibration is required with our 18ct control sample.
  
  
• We get around 3 months and test around 10 times a day, often 15 times a day. Overall we think they last well. 

• Our probe only lasted 3 months, we are very disappointed.

• It's variable, some probes last approximately 12- 18 months each (about 2000 tests) and some  9 - 12 months (about 1000 tests). 
  
  
• The probes seem to last us at least a year, I would say that it was at least 200 individual tests, and perhaps even up to 400 tests over that period. 

• Sometimes a probe lasts a few months but sometimes only a few weeks.

Conclusion: 

• Generally, a pen-probe lasts between 3 and 18 months but it can be as long as 2 years or as short as 6 weeks - the guaranteed is one month from the date of purchase.

• Although the manufacturers recommend you change it after a year, if it's still working, it's fine. Providing you are still able to calibrated the tester, you will get accurate results.

• The date on the sticker on the pen-probe is so that we know which batch it comes from and so that you have an idea when it's getting to be a year old. Irrespective of the date on the sticker, the guarantee is one month from the date you purchased it.
