Details
The weights of these calibration samples vary slightly but are approximately 0.4g.
Electronic testers need to have their electronics matched (calibrated) against known samples.
The price of gold is volatile, we change the price of these samples each week, depending on how much the gold price has gone up or down.
For the Auracle ANALYZER and PRO testers you need 18ct
For the Gemoro AGT3 you need 14ct and 18ct
For the Gemoro model AGT1 you need 14ct
For the KEE you need 18ct, but also 22ct if you want to test high-carat accurately.
You don't have to buy our samples! But if you use your own, check that each has a full British hallmark to guarantee the carat. And they must be yellow gold (not white).
Sample size (approx. 0.4g): 14ct calibration sample (for AGT electronic testers), 18ct calibration sample (for ANALYZER, PRO and KEE testers), 22ct calibration sample (for KEE electronic tester)
