For many years, isotope density devices were the only option for measuring density. However, ultrasonic analyzers developed by Rhosonics are now increasingly being used.

The new technology has a number of advantages, including increased productivity, elimination of risks associated with radioactive technologies, reduced maintenance costs, and ease of installation and calibration.

There is no need to employ certified radiation safety personnel (RSO) or obtain special licenses to operate these analyzers.

The analyzers provide high accuracy and fault tolerance and are suitable for various types of pulps.
