300g DahoMeter Digital Portable Gold Content Tester , Electronic Densimeter Gold Karat Testing Machine
Application:
pawn broking, bank, jewelry shop, precious-metals recovery, jewelry factory, Gemstone Testing Center,precious metals researching.etc.
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;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.
K value of gold,PT value of platinum,density value,purity percentage can be measured.
Specifications:
Model:DH-300K
Density resolution:0.001g/cm3
Weight resolution:0.05g
Necessary weight for density:4g
Features:
Measurement Procedure:
a) Place sample on testing board to measure weight in air,press ENTER key to memory.
b) Place sample into water to measure the weight in water,press ENTER key.the K value of gold,purity percent,density value will be displayed.
Standard accessories:
Host,sink,test board,tweezer,thermometer,weight,wind and dust cover,a set of measuring particle parts,a set of measuring floating body parts,power transformer

Our Advantages:
Our machine has the interface of RS-232C.which can be connected with computer or printer.
For connecting computer,there is no need to install extra driver or software in order to output data from density meter to computer.the driver is including into the windows system when install initially,all need to do is setup one parameter (which is Baud rate) of computer to 9600.Then all is done.
Operation like this:(windows system)
Control panel------>Accessibility options------->general
option------>serial key devices (check)------>serial
port:COM1(check);baud rate:9600(check)------>done
Parameter setting for the gold testing machine:
Long press Zero + C key at the same time,the screen will be
displaying AUT 1,If not,press B key to shift it to AUT 1,Press A
key to change AUT 1 to AUT 0,press ENTER to confirm.
After connect to computer.need to creat one new excel.open the
excel,choose one blank space.
When the gold testing machine do the testing .the testing result
will be displayed at the blank space automatically.
