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

DA-100 Operating Charateristics

  • 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 and Printer Options

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

Test Density On-site With A Portable Gravity Meter 

The DA-130N portable density/specific gravity meter is ideal for obtaining liquid property information on-site quickly.da130n_1.jpg

Typical applications include:

  • Density measurement of crude oil, fuel oil and lubricant oil.
  • Oscillation method is specified in ASTM D 7777.
  • Density or Brix measurement of various beverages such as milk, soft drink, fruit drink, etc.
  • Measurement of alcohol or extract concentration of beer, whisky, wine, shochu(Japanese distilled alcohol), Japanese sake(fermented alcohol), etc.
  • Measurement of Brix or constituent concentration of food materials for quality control purposes.
  • Density or Specific Gravity measurement of oils and fats such as vegetable oilanimal fat and oil, etc.
  • Conforming to Japanese Pharmacopoeia.
  • Concentration check of etching solution or acid pickling solution for electronic parts.
  • Concentration check of flux or plating solution.
  • Learn about 5 ways we use liquid density information.


Suctioning and draining can be done with your thumb and forefinger.  Once you stop pressing, operation will stop.  Measurement can easily be done with your thumb, enhancing efficiency of your work.
