21/02/2021& 0183;& 32;Gold testing equipment is useful for valuing gold although some gold testers have more features and better accuracy than others. You may prefer a testing kit over an electronic gold tester. Alternately an electronic pen is small and lightweight to use but may not offer all the features of a larger device. Decide whether you prefer a gold tester for testing gold content only or if you require a

18/12/2017& 0183;& 32;Accuracy is an indi ion of the correctness of a measurement. Because at a single measurement the precision affects also the accuracy an average of a series of measurements will be taken. The uncertainty of measuring instruments is usually given by two values: uncertainty of reading and uncertainty over the full scale.
Gold bullion bars have been fraudulently adulterated through the insertion of slugs of inexpensive base metal of similar density. These insertions are difficult or impossible to detect through weighing radiography or X-ray fluorescence so some precious metals processors have resorted to drilling or cutting bars to verify integrity. However a simple ultrasonic test can quickly and reliably lo e inserts

The test equipment being calibrated can be just as accurate as the working standard. If the accuracy ratio is less than 4:1 then the calibration tolerance can be reduced to compensate. When 1:1 is reached only an exact match between the standard and the device being calibrated is a completely correct calibration.

Pure gold is heavy due to its high density 19.32 g/ ml . If your gold item floats or hovers above the cup’s bottom then it’s fake or plated gold. This is because its density is lower 14K is 12.9 to 14.6 g/ml 18K is 15.2 to 15.9 g/ml and 22K is 17.7 to 17.8 g/ml. However the Float Test is not a 100% accurate test because the fake item can have other heavy metals that sink as well. This is why it must be a
