| Nano bubble testing | Nano bubbles can exist for weeks to months, and can be sampled and sealed for testing to obtain a large amount of data and charts such as nano bubble particle size and concentration | Malvern Nanosight | Light scattering method | ||
| Micro bubble test | Due to the short lifecycle of microbubbles, sampling and measurement are not possible. In situ immersion online observation is used to obtain a large amount of data such as micro bubble particle size, and observe the real-time action and change process of micro bubbles | JWNP-WJS series | Microscopic imaging method | ||
