Product Features
① ISO7027-Compliant Optical Design
Utilizing a 135° backlight scattering method, the sensor adheres to the ISO7027 standard for turbidity and TSS measurement. This ensures global compatibility and reliable data accuracy across applications.
② Anti-Interference & Sunlight Resistance
Advanced fiber-optic light path design, specialized polishing techniques, and software algorithms minimize signal drift. The sensor operates accurately even under direct sunlight, ideal for outdoor or open-air installations.
③ Automatic Self-Cleaning Mechanism
Equipped with a motorized brush, the sensor automatically removes fouling, bubbles, and debris from the optical surface, ensuring long-term stability and low maintenance.
④ Compact & Durable Construction
The 316L stainless steel body resists corrosion in aggressive environments, while its compact size (50mm × 200mm) simplifies integration into pipelines, tanks, or portable monitoring systems.
⑤ Temperature & Chromaticity Compensation
Built-in temperature compensation and immunity to chromaticity variations guarantee consistent readings in fluctuating water conditions.
Application
1. Industrial Wastewater Treatment
Monitor TSS levels in real time to optimize sludge dewatering, discharge compliance, and process efficiency.
2. Environmental Water Monitoring
Deploy in rivers, lakes, or coastal areas to assess sediment load, erosion, or pollution events.
3. Drinking Water Systems
Ensure water clarity and safety by detecting suspended particles in treatment plants or distribution networks.
4. Aquaculture & Fisheries
Maintain optimal water quality by tracking suspended solids that affect aquatic health and equipment performance.
5. Research & Laboratories
Support high-precision studies on sediment transport, water clarity, or environmental impact assessments.
6. Mining & Construction
Monitor runoff water for regulatory compliance and mitigate environmental risks from suspended particulates.
