Applications
Designed for continuous transparency monitoring in surface water, urban rivers, lakes, reservoirs and aquaculture. Transparency is also a useful indicator for monitoring black and odorous water bodies and changes in suspended or colored material.
Installation & Integration
The digital RS485 interface supports direct system integration. For project selection, provide the expected transparency range, water-body type, flow conditions, mounting depth, cable length and whether automatic cleaning is required.
