Model 375 Volumetric Karl Fischer Titration Workstation
For water determination from 100 ppm to 100%

The Denver Model 375 makes quick, easy work of common KF titrations, because the titrator arrives pre-programmed for your specific applications. Setup is simple and you’re titrating in no time. Typical results, obtained in minutes, are repeatable with a relative standard deviation of less than 1%. All this precision, and it’s affordable too!
