Metal purity tester PS/X/AU

waga jubilerska PS 200/2000/X/AU

Metal purity tester PS/X/AU series special design of the container and dedicated software, allow for density determination of metals. Application of the method for density determination provides the following options:

  • Determination of carat value of gold,
  • Density determination of platinium,
  • Density determination of other metals.

Thus, the software has the option of distinguishing precious metals from counterfeited by density determination of a sample.

Balances for testing gold may cooperate with a temperature sensor used for measuring liquid temperature.


  • Units of measurement: [g], [mg], [ct], [lb],**, [oz],** [ozt],** [dwt],**
  • Additional units: [K], [cm3], [g/cm3], [oz/gal], [°C], [°F], [%],
  • Autozero function,
  • Adjustable baud rate of data transmission,
  • Continuous data transmission for RS 232 protocol,

PS/X/AU series of precision balances feature large graphic backlit display. The housing is made of ABS material.
The balances design incorporates a liquid container with a weighing pan has a form of a dedicated adapter. The construction of the adapter enables weighing of an object in the air and then on the pan immersed in the liquid. The adapter design facilitates easy and quick setup.
Balance PS/X/AU series features a 12 key membrane keyboard , and it comes standard with interfaces USB, RS 232 with slot DB9/M.
The balance is powered from an external adapter 230VAC / 13,8VDC.

Optional liquid temperature sensor:

Balance PS/X/AU series enables cooperating with a liquid temperature sensor TB-2. On assembling the temperature sensor, balance’s software automatically detects its presence and includes the value of measured liquid temperature when calculating carat value of gold, density of metals and in all other calculations.
