Model 87 Lab Analyzer
The Model 87 is a lab adaptation of the Nusonics line of Sonic Concentration Monitors, used in both industry and research for over twenty years. Employing acoustic technology, the Model 87 continuously samples the sound velocity and temperature of a liquid and produces a concentration output based on those measurements.
Features of the Model 87:
- Displays concentration in a variety of units
- Instantaneous Measurement- Faster, easier, and more repeatable than titration
- Up to 0.02% by Weight Accuracy
- No moving parts and virtually no maintenance
- Measure acids, bases, organics, polymers and many others
See the Model 86 for additional information on Sonic Concentration Monitors.
