AL-20 At-Line Surface Tension Monitor

Check the level of surface active chemical additives and impurities in water-based process liquids quickly and easily by measuring surface tension. The operator can then dose the process with surfactant until the surface tension is at the desired level.

The AL-20 is ideal for regular or continuous sampling of process liquids and Statistical Process Control.
