The dimensions of the sink are 15.3cm in length, 10.7 cm in width, and 8.0cm in height (can be customized according to the measured product size)

Measurement function: Gold K value,% content, density value; Platinum PT value,% content, density value;

Silver S value,% content, density value; % content and density value of other alloys

Gold K value (1-24K)&content%

Measurement principle Archimedes principle buoyancy method

Measurement time is about 5 seconds to 20 seconds

Measurement step 1: First measure the weight in the air and press the ENTER key;

② Put it back into the water to measure its weight, press the ENTER key, and the result will be displayed

Parameter settings include water temperature setting, measurement medium density setting, air density setting, primary and secondary material density setting, and copper silver ratio setting

The range of copper silver ratio can be cyclically switched between 8/2, 7/3, 6/4, 5/5, and 4/6; The default setting is 7/3

Calibration method: single key calibration, automatic detection

Product Features:

1. Can quickly and accurately determine the purity% of precious metals and the K number of gold: only two weighing steps are needed.

2. After measurement, there will be no traces or contamination left, and there is no need to use sulfuric acid solution or test standard samples.

3. It can also be easily determined for Brazilian fired gold with a coating thickness greater than 30 μ m.

4. Special software design that can directly display the K number of gold (gold, copper, silver, gold, copper) in a loop, gold

Purity% (gold, copper, silver, gold, copper)

5. With upper and lower limit functions, the wide range of K numbers from 9 to 24K allows for free setting of HI and LO data.

6. It has a mixing ratio function and can test other precious metals. Such as platinum, silver, palladium, copper, rhodium, etc.

7. Adopting a large water tank design to reduce the error caused by the buoyancy of the suspension line.

8. Cannot test samples with gemstones or hollow cores. Can be used as a general balance
