Description

Technical Field

[0001] The utility model discloses a film pressing ring, belongs to the technical field of algae detection filter membranes, and particularly relates to a film pressing ring used for algae detection filter membranes. Background Art

[0002] Algae detection membranes are used to filter water samples for the detection and analysis of algae. They effectively separate algae cells from water samples for subsequent microscopic examination or other analysis. These membranes typically have a specific pore size to capture algae of varying sizes while allowing other smaller particles to pass through. This method improves the accuracy and efficiency of algae detection, helping to monitor water quality and prevent water pollution.

[0003] In-situ algae detection equipment is an automated wireless device for use on water, lakes, and oceans. Currently, algae density is measured using a cellulose membrane, filtered through a sand core. However, due to the 0.1mm thickness of the cellulose membrane, the automated in-situ detection requirements cannot be met. Utility Model Content
