Krüss density meter
Digital density meters – Precise laboratory and industrial measurement with modern technology
With their compact design, high precision and user-friendly interface, Krüss digital density meters are reliable instruments for quality control and laboratory automation worldwide. Modern measuring cells, automatic temperature compensation and advanced software support ensure that every measurement is fast, repeatable and accurate.
The Krüss range extends from entry-level compact density meters to high-accuracy professional laboratory models.
They are ideally suited to determining the density and concentration of liquids.
Automatic temperature control
Stable temperature is one of the most important factors in density measurement. Krüss instruments provide precise temperature control and extremely rapid thermal stabilisation, allowing the measuring cell to reach the set temperature within moments.
Intuitive software and data management
Modern touchscreens, cloud-based data export, LIMS compatibility and large storage capacity support efficient laboratory automation. Access management, electronic signatures and audit-trail functionality allow the instruments to be operated in a 21 CFR Part 11-compliant mode when required.
Combinable measurement systems
Krüss density meters can be easily integrated with refractometers, polarimeters or other analytical instruments to create a comprehensive quality-control system.
Ideal applications:
- Food industry (e.g. sugar solutions, beverages and dairy products)
- Pharmaceutical and chemical industries,
- Research and development (R&D) and teaching.
