API degree, specific gravity or density, acid number (TAN), base number (TBN), refractive index, water content, sulphur, mercaptan … there is probably no other industry where that a wide variety of different parameters must be determined in quality control as in the petroleum industry.
Our offering includes four product lines which are required in almost every petrochemical laboratory:
Density Meters
to determine API gravity, density and specific gravity.
Refractometers
with built-in solid state thermostats.
Potentiometric Titrators
to perform determinations of the acid and base number (TAN and TBN), the sulphur (Thiol, Mercaptane) content, etc.
Karl Fischer Titrators
for volumetric and coulometric moisture determinations in petroleum products.
ASTM and ISO Petroleum Standards
In most petroleum laboratories, testing of the composition, purity, density, etc. is done according to ASTM or ISO petroleum standards.
