Quick and acurate density measurements on site

With our portable density and concentration meter DA-130N you can measure density or alcohol consentration just in few seconds in the laboratory and on-the-go in the production site or warehouse for incoming or final products.

Main features and advantages:

  • Light, robust and accurate handheld instrument
  • Density measuring range: 0.0000 to 2.0000 g/cm3 with accuracy ±0.001g/cm3
  • Capable of measuring samples of up to 2000 mPa·s of viscosity.
  • The display shows density, temperature compensated density, specific gravity, temperature compensated specific gravity, Brix %, alcohol concentration, sulfuric acid concentration, API degree, Baume degree, Plato and Proof degree and the like.
  • Measurement of alcohol or extract concentration of beer, whisky, wine, etc. is possible.
  • Only 2 ml of sample required.
  • Compliant with ASTM D7777 for liquid petroleum products (crude oil, fuel oil and lubricant oil)

Taking the Karl Fischer Moisture Titrator into a new stage

Hybrid Karl Fischer Moisture Titrator MKH-700 has the world’s first & convenient functions equipped such as high-speed & high-precision measurement by “Hybrid titration method” which uses both “Volumetric titration method” and “Coulometric titration method”, and “Electrolytic Factor Measurement System” which does not require pure water for factor determination.
mkh7001
Karl Fischer Moisture Titrator which is on the market is necessary to adjust the sample amount when carrying out the measurement.
“Hybrid titration method” automatically switches between the parallel measurement by “Volumetric titration method” and “Coulometric titration method” by monitoring moisture content in titration cell with high-speed & high-precision measurement, therefore can measure without adjusting the sample amount.

With just pressing one button, the “Electrolytic Factor Measurement System” automatically performs the factor determination of Karl Fischer reagent, and save the time & work without using pure water.
