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
  

Benefits

• Eliminates overdosing of surfactants - reducing costs
• Controls processes - improves efficiency and quality
• Reduces waste and improves yield
• Improves environmental control
• Extends chemical lifetime in processes
