HZ300K Precious Metal Gold Purity Tester
Principle
HZ300K gold purity tester is according to the Archimedes principle of buoyancy method, accurately and quickly read the precious metal density and purity%
Use:
Jewellery, banking, pawnshop, gold and precious metals research laboratories.
The measurement leaves no traces or pollution, eliminating the need for sulfuric acid solutions or test standard samples.
Gold plating with a thickness of 30 microns or more can be easily determined.
Equipped with upper and lower limit settings, allowing a wide K-value range from 9K to 24K to be freely configured with HI and LO data.
Samples with gemstones or hollow structures cannot be tested. The device can also be used as a general balance.
Measurement step
Remarks:
There are four kinds of measurement models for the purity tester of precious metals: D-G (pure gold mode), D-K (K gold mode), D-p (Platinum) and D-a (purity of silver). Before the test, please confirm the pattern.
The setting of the measurement mode: in 0 state, the "MODE" key is pressed into the measurement mode setting.
Press the "SET" key to modify the setting parameters and press the "ENTER" key to exit the setup mode.

1. Open the machine, the display will change from 99999 to 0.00g if not 0.00g, then the ZERO key to zero.
2. With no sample on the measuring table, after stabilization, press the ENTER key. "SAV-A" will appear, indicating that the sample weight in air has been recorded. At this point, the lower corners of the screen will display "LIq".
3. Put the sample into the water suspension bar and press ENTER after stability.
4. Calculate the mean value of the weight of the water and remember.
5. Screen directly shows the density value. According to the "MODE" button, it can switch the volume of display sample, P-1 gold + copper, purity, K-1 gold + copper, K number, P-2 gold + silver, purity, K-2 gold + silver, K number, P-3 gold + silver + copper, purity, K-3 gold + silver + copper, K number.
6. According to the "PRINT" key, we can input data of test results through RS232 communication or print out test time and statistics test data through special micro printer.
7. According to the "SET" key to return to the test state, the next group of samples can be measured. (the same sample needs to be retested when it is dry and must be more than 5 minutes)
