RHOTEC L  Laboratory high precision digital densitometer

The Principle

RHOTEC L continuously measures the density of liquids. Designed for laboratory applications that require maximum sensitivity and high accuracy, this device is ideally suited for extremely small sample volumes. For density measurement, the liquid flows through a U-shaped tube. While the tube is electronically excited to oscillate at resonance, the oscillation frequency is observed. Any change in the fluid density has an impact on the detected signal and can thus be identified. As a specific property of each liquid, the correlation between concentration and density can be described by a mathematical polynomial. With decades of experience and own laboratory facilities, we have a particular knowledge of the polynomials for a huge number of products. Any temperature drifts of the measured signal are automatically compensated for by an internal Pt1000 sensor. RHOTEC L is equipped with a very quick and accurate temperature controller based on Peltier technology. The 10” touch screen, the compatibility of the software and various interfaces for data exchange make RHOTEC L extremely user-friendly. The instrument displays various units, e.g. vol.%, mass %, °Brix and °Plato
