The DS300 Series online digital transparency sensor is used as an indicator for judging the degree of black odor in black and smelly water. It is based on the combined infrared absorption and scattering method. Transparency is closely related to light penetration and attenuation in submerged ecosystems and is important for monitoring changes in water ecology and biogeochemical processes, such as photosynthesis and growth of phytoplankton, sediment transport and resuspension.
The DS300 sensor adopts dual-beam infrared scattering photometer detection technology, which has good repeatability and stability. The cleaning scraper (optional) offers an automatic cleaning function to minimize the maintenance of the sensor. DS300 is suitable for monitoring surface water, aquaculture, inland rivers, lakes and reservoirs.
