Density Meter

Oscillating U-tube Technology

A.KRÜSS Optronic Density Meters

The measurement of the density of an aqueous solution can be utilized to identify substances, to determine their quality or purity and to measure their concentration in binary or quasi-binary mixtures. This digital density meter for liquids is a common tool utilized for quality assurance in the pharmaceutical, food & beverage, chemical and petrochemical industries.  For more information about A.KRÜSS Density Meter technology and applications, click here to visit the A KRÜSS Optronic Campus.

A.KRÜSS optical density meters utilize the highly accurate oscillating U-tube method in combination with controlled temperature for simple, fast and precise measurements of all flowable media, including viscous ointments and creams. These oscillating U-tube density meters also provide information concerning substance conversions and reaction dynamics. Their accuracy and versatility are two of the biggest reasons these density measurement instruments are vital equipment across a broad range of industries.

Key Features
