Standard:

In accordance with Archimedes principle water buoyancy method, GB/T1423 of precious metals testing standard,and so on.

Application:

The high-precision gold purity tester will not damage the sample, can quickly, easily, and accurately distinguish and

test the K value of gold, the PT value of platinum,the purity percentage of other precious metals, and their density.

It is suitable for the jewelry shop,pawn broking, bank, precious-metals recovery, jewelry factory, Gemstone Testing Center,

precious metals researching laboratories.etc. It can measure precious metals such as gold, karat gold, platinum, platinum, and silver.

Advantage:

Quickly test the purity of gold, platinum, and other precious metals,distinguish fakes.
Non-destructive testing, clean and environmentally friendly, with no damage to the original sample.
Fast and convenient testing,just need 10 seconds, stable and accurate.
Multi-mode: freely switch between gold, platinum, and other precious metal modes.
Multi-function: it can measure the purity of other precious metals, such as tin, copper, and silver, can also be used as a precision balance.
With upper and lower limit functions:it displays OK, HI, LO based on the status of qualified, exceed,less with an alarm.
Cannot measure hollow samples or samples inlaid with gemstones.
With fully automatic zero tracking, buzzer alarm, and overload alarm functions.
Uses water as the medium, other liquids are also acceptable. The actual water temperature can be set.
Compared to traditional drop-in-water methods, this unit utilizes a single-piece, large-capacity measuring instrument.
The water tank is corrosion-resistant, drop-resistant, and break-resistant, and the hanging wire will not affect the measurement results.
Standard with RS-232 output port.
Printer is optional,can print the testing result directly.
Standard with dedicated windproof and dust-proof cover,easy assembly.
High-precision, suitable for small samples and demanding applications.
