    Marine TransmissoMeter

    Overview Products Knowledge Standards Terms
    The marine transmissometer measures changes in transmitted light intensity by projecting a light source into the water, calculating the transmittance of seawater. It is used to assess water transparency, plankton distribution, and pollutant diffusion, and is commonly employed in marine environmental monitoring and ecological research.
    Selection
    When selecting, consider the measurement depth range and the instrument's pressure resistance rating, ensuring compatibility with common seawater light transmission bands. Focus on sensor accuracy and anti-biofouling design. Verify the length of underwater cables and the compatibility of data interfaces. Prioritize materials with corrosion resistance and on-site calibration capabilities.
