The automobile industry, can and bottle manufacturing, metal processing, food and pharmaceutical packaging are examples of industries where production cycles often involve a step for cleaning of manufactured parts or for lubricating parts for production line speed efficiency. The liquid formulations for degreasing, cleaning, lubrication or surface treatment widely utilize chemical additives such as surface active agents in the process liquids in order to optimize process conditions. The surface tension of water based solutions correlates with the amount of surfactants in the formulation. Monitoring the surface tension of process liquids allows operators to add the correct dosage of chemicals into the process. This leads to reduced costs, improved efficiency and better quality, higher yield, increased environmental waste monitoring and extended process lifetimes. The AL20 and OL55 industrial tensiometers from Attension enables checking the levels of chemical additives in process liquids by measuring the surface tension either at-line or on-line, respectively. By contrast, BPA-800P measures the dynamic surface tension and is highly suitable for process liquid optimization in pre-studies in the laboratory environment.
