The Portable Digital is a highly accurate, handheld device designed for determining the density, relative density, or API gravity of liquid petroleum products. It offers a practical solution for field testing, especially where laboratory conditions are unavailable.

Portable Digital Features :

• Density measurement of crude oil, fuel oil and lubricant oil
• Oscillation method is specified in ASTM D7777
• 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 SG measurement of oils and fats such as vegetable oil, animal 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

For the determination of the density, relative density, or API gravity of liquid petroleum products using portable digital density meters at test temperatures between 0 and 40°C (32 to 104°F). Its application is restricted to samples with a dry vapor pressure equivalent up to 80 kPa (11.6 psi) and a viscosity below 100 mm2 /s (cSt) at the test temperature.
