Accuracy of measurement is ±0.001g/cm3 by measuring resonant frequency.


  • Temperature can be selected in the range from 15 deg. C to 40 deg. C by 0.1 deg. C step. Also setting in deg.F(59°F ~104°F, 1°F step)is available.
  • Can convert density/specific gravity to concentration value and display the result. Conversion Equation is linear and display is in 12 different units. It enables more efficient and effective routine measurement than conventional measurement with hydrometer for API degree. Baume degree and others.
  • Can output data of density, specific gravity, concentration values, date and time, etc through RS-232C and can be connected to an external computer or an optional printer. (External computer and printer cannot be connected at the same time.)
  • Parameter setting and operating is designed user-friendly, easy to use, being guided by dialogue message on display.
  • Purge pump is equipped as standard to desiccate the measuring cell.
  • Easy factor calibration of measuring cell can be performed using air and pure water. No complicated calculation is required.


  • Auto Sampling Unit.  The built-in sampling pump controls sampling, draining the sample, and rinsing and drying.
  • Printer

DA-130N Portable Density Meter
