Precious metals Purity Detector

DH-300K DE-120K Precious metals Purity Detector

Application: jewelry shop,pawn broking,bank, precious-metals recovery, jewelry factory, Gemstone Testing Center,precious metals researching.etc.

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

Combine archimedes principle with micro electronic technique and adopt sensor imported from Germany,the purity can be calculated through measuring density of precious metals; Features of no damage on sample; Simple operation; Fast and accurate; Distinguish.K value of gold; PT value of platinum,density value,purity percentage can be measured.

Specifications:

Model:DH-300K DE-120K

Density resolution: 0.01 g/cm3 0.001 g/cm3

Maximum weigh:300g 120g

Minimum weigh:0.01g 0.001g

Measuring time:10s 10s

Features:

The purity of gold,platinum,and other precious metals can be tested in a short time.the fake can be

distinguished.

No damage testing, cleaning and environmental protection.

Measuring just need 10 seconds;Convenience;Stabilization,and accuracy.

Multi-mode,gold mode,platinum mode,other precious metals mode can be switched.

Multi-function,the purity of other precious metals can be measured.such as tin,copper,silver .etc.

also can be used as precision balance.

Function of top and bottom limitation; It can display OK,HI,LO in the state of qualified,exceed,

less.and prompt alarm.

Function of automatic zero tracking,buzzer warning,and overload warning.

Function of solution compensation.necessary if liquid other than water is used as a medium for measuring.

Adopt the unicase high-capacity measuring accessories with the transparent injection mould tank,which can resist wear,fall off,and corrosion.

Adopt the unicase dedicated wind and dust cover,which makes the combination convenient and durable.

Interface of RS-232C is included.the printer of DE-40 will be available to connect PC with printer.

Measuring Procedure:

Measure gold weight in air,and then press ENTER button to memory.

Place gold into water to measure weight,and then press ENTER button to memory.The K value of gold,purity percent,density value can be displayed.

Standard Accessories:

Host,tank,testing board,tweezer,thermometer,weight,wind and dust cover,a set of measuring

particle parts,a set of measuring floating body parts ,power transformer
