High precision Gold Purity Density Test Machine gold tester gold purity tester price

Principle: Accurately and quickly read gold (k number), density and purity% according to Archimedes’ principle buoyancy method.

Specifications: (The following three models can use the silicone oil method to measure the product density, if you need the mercury method, please contact the supplier)

Functional characteristics and devices:

1. Quick and accurate determination of precious metal purity% and gold K number: only two weighing steps are required.

2. No trace or pollution will be left after the measurement, no need to use sulfuric acid solution or test standard samples.

3. It is also easy to judge the Brazilian fired gold with the coating thickness> 30μm.

4. Special software design can directly display the gold K number (including gold, copper, silver, gold and silver,

Gold copper), gold purity% (including gold copper silver, gold silver, gold copper)

5. The K number ranges from 9 to 24K.

6. The large sink design is adopted to reduce the error caused by the buoyancy of the hanging rail.

7. Samples with gems and hollows cannot be tested. Can be used as a general balance

This machine adopts one-piece injection molding measuring frame, one-piece injection molding transparent sink, easy to assemble, wear-resistant, drop-resistant, anti-corrosion, can clearly observe the sample in the medium.

Gold density and purity K number measurement steps:

1.Put the gold into the measuring platform, measure the weight in the air, and press the MODE key to remember.

2.Fully immerse the sample in water, measure the weight in the water, press the MODE key to memorize, and directly display the density value.

3.Press the O button to display the purity of gold; then press the MODE button to display the gold K number.
