8500 Series

Ultrasonic process concentration analysers.
The model 8500 is a single channel ultrasonic inline concentration analyzer, for accurate concentration measurement of chemicals in many industries, like in electrolyte solutions, water or chemical purity and solvent concentrations.

8500 Ultrasonic Process Concentration Analyser

The RHOSONICS Model 8500 is the newest and most powerful instrument to measure the composition of industrial liquids. Thanks to the innovative electronics and sensor design, continuous in-line monitoring of diluted solutions is now possible with an extreme accuracy, virtually no maintenance and without moving or degrading parts. Model 8500 operates with the UMP or UFTC series of probes, available with several process connections and materials such as 316L, Hastelloy and PEEK.

The measurement technology for the model 8500 is only based on speed of sound determination in combination with high accuracy temperature measurement. Depending on the application and mounting possibilities, we can offer reflection or transmission probes.
