Replacement probe for AGT electronic gold tester.

You MUST calibrate the tester when you plug in a new probe, so please make sure you have a sample of 14ct yellow gold (must be yellow gold, must be exactly 14ct).


The last time we bought these from the supplier in the USA they quoted a month for delivery. Then, every week, there was a delay and in the end it took over three months.  Since these have a limited shelf life, we are now getting these as a special order only with delivery theoretically one month but could be over three months. 


This is a 'consumable'. Consumables cannot usually be returned if unsuitable.

When an AGT1 or AGT2 tester stops working, it might be because it needs a new probe but it might be because the machine has developed a fault. Maybe it does need a new probe...but it might also have developed a fault. Maybe it was working fine the last time you used it...but it might have developed a fault.

Since we have no way of knowing if your tester is faulty or if it just needs a new probe (we discontinued this item a few years ago so we have no way of checking the probe) - you may it for refund providing it is posted back to us within three days of receipt. POSTAGE IS NOT REFUNDABLE.

Please note, an AGT2 will stop working if you have upgraded your phone or its operating system since 2019. A new probe will not fix this. The app. for this product has been discontinued and is no longer available for download. 


Ask a Question
  • Can you use this probe with another gold meter tester? If same plug attachment?

    The probe can be used with AGT1, AGT2 and AGT3 testers only.

    It MIGHT have the same plug as other models, but it will only work with the above.

  • Hi are able to supply the tester (GemPro)? We are needing two machines.

    These models (the complete testers) are not longer available due to lack of electrical approval certificates for the UK/EU.

    This product is the replacement pen-probes which we still stock. 

  • Hi there Do you stock a UK AC mains adaptor for the AuracleAGT1 PLUS Gold Tester?
