Chelsea Alphatracka MKII Transmissometer

The Chelsea Alphatracka MKII Transmissometer is an optical instrument used in marine research, primarily for measuring the light transmissivity of water, which reflects the degree of absorption and scattering of light in the water body. This measurement can provide insights into the water transparency, suspended particulate concentration, or turbidity variations.

Basic Functionality:

• Light Emission: The device emits light at a specific wavelength (e.g., 660nm) through a known length of water path (such as 25 cm).

• Detection: A receiver detects the intensity of light after it has passed through the water, allowing for the calculation of light transmissivity.

• Estimate Parameters: The transmissivity data can be used to estimate the concentration of suspended particles, organic materials, or turbidity changes in seawater.

Common Applications:

• Marine and Lake Water Quality Surveys: To assess the clarity and pollution levels in water bodies.

• Biogeochemical Research: For studying interactions between biological and chemical processes in aquatic environments.

• Automated Monitoring Systems: Often deployed in CTD (Conductivity-Temperature-Depth) or ROV (Remotely Operated Vehicles) systems for continuous data collection and observation.
