Flow Cell Type Lower Range Lazer Tubidity Sensor For Drinking Water
The Daruifuno OLTU601 is a cutting-edge laser flow-through low turbidity sensor featuring an integrated display screen for immediate data visualization. This innovative sensor precisely measures turbidity or suspended particle concentration in liquids using advanced laser technology, providing real-time results directly on its built-in display. Users benefit from the convenience of accessing measurement values, units, and other pertinent information without the need for additional external equipment.
How it Works: Precision Laser Scattering.
The OLTU601 operates on the fundamental principle of laser light
scattering. A focused laser beam illuminates the liquid sample. Any
suspended particles within the liquid cause the laser light to
scatter. An integrated light receiver within the sensor detects the
intensity of this scattered light. Crucially, the intensity of the
scattered light is directly proportional to the concentration of
suspended particles in the liquid, enabling highly accurate
measurements.
Unmatched Sensitivity and User Convenience
Distinguishing itself from conventional turbidity sensors, the
Daruifuno OLTU601 offers superior sensitivity and accuracy.
Leveraging the unique properties of laser beams, this sensor
achieves precise measurements even at exceptionally low turbidity
levels. Furthermore, the integrated display screen enhances user
experience by presenting measurement results intuitively,
streamlining both operation and data collection processes.

Features
The Daruifuno OLTU601 flow turbidity sensor employs a sophisticated laser light scattering principle for highly accurate measurements. A 660nm laser is directed vertically downwards into the water sample. As the laser interacts with suspended particles, light is scattered. The sensor's embedded silicon photocell receiver, submerged within the water, precisely captures this scattered light at a 90° angle relative to the incident laser, enabling the calculation of turbidity.
