2.Is the test result accurate? What's the margin of error?
Our gold tester uses high-precision XRF (X-ray fluorescence) technology with typical accuracy within ±0.01% to ±0.1%. The accuracy varies with different machine configurations.Regular calibration ensures long-term stability and accuracy.
3.Does testing damage the sample?
No. This is a non-destructive testing device. The sample remains intact and can be tested multiple times without any damage.
4.How long does a gold tester take to test a sample?
Our instruments displays the preliminary analysis data in about 3 seconds and completes the sample analysis in 30 seconds.
5.Is there a warranty and after-sales support?
