Ross-Miles foam meter is an instrument that uses the solution falling method to measure the foam activity value of soap, synthetic washing powder, laundry soap powder, shampoo, shampoo, dishwashing liquid (table detergent), hand soap and other detergents. The solution falls downward from a certain vertical position, and foam activity occurs in the small center of the graduated tube. The height is measured and the foam activity value is determined. It meets the technical requirements specified in GB/T7162-94; ISO696-75 national standards and departmental standards.
1. The Roche foam meter must be installed vertically, otherwise the liquid surface will be uneven and the reading will be inaccurate. 2. The test solution should be preheated to about 41.5ºC before being placed in the dropper. The temperature during formal operation after injection should be 40ºC±0.5, otherwise the temperature will have a great impact on the data. 3. The foam activity of some solutions is very unstable. After a few minutes, the foam surface will break and become an uneven surface. At this time, the height reading can only be an estimated average number.
