OL-55 On-Line Tensiometer

By continuously measuring surface tension, the�OL-55 monitors the level of surface active chemical additives in water-based process liquids. Based on the information from the measurement the operator can either manually dose chemicals into the process or the optional auto-dosing system can be used.

On-line tensiometer

Continuous monitoring of surface tension and other parameters, including pH, temperature, and conductivity, in various process liquids for optimising the dosing of chemicals
Rugged design for factory applications
Fully automatic computer controlled operation
Patented technology
