Shanghai Longtuo Professional Supply Improved Ross Foam Meter is widely used in foam fire extinguisher, foam flotation, foam drilling fluid surfactant determination, cosmetics, detergent, grain and oil production, food inspection, petrochemical and other industries.


Improved Ross method for surfactant detection:
(1). Longtuo's modified Ross surfactant detection principle is to measure the volume of foam after 500mL of surfactant solution is free flowing from 450mm to the liquid surface of the same solution.
(2). The 500 mL solution was continuously flowed down until the water level dropped to the 150 ml mark line, and the outflow time was recorded. All measurements of the difference between the outflow time and the observed outflow time arithmetic mean planting greater than 5% should be ignored, and an abnormally long time indicates the presence of air bubbles in the metering tube or cock. The foam volume (foam only) was measured at 0.5 min, 3 min, 5 min after the flow was stopped. 2152 Modified Foam Meter (Improved ROSS-Miles Method) Improved Ross Foam Meter, Surfactant Tester
