Unique dual light path, dual detector turbidity measurement system

·LED light sources have a longer lifespan (up to 100000 hours) than traditional tungsten light sources, do not require replacement of the light source, have better stability and accuracy with temperature changes, shorter preheating time (about 1 second), and good shock resistance
·90 ° scattered light detection
·The design of dual light paths and dual detectors determines turbidity by measuring the ratio of the light beam to the reference beam, effectively compensating for colored samples
The system design complies with multiple turbidity detection standards
·Simultaneously comply with EPA 180.1 and ISO 7027 turbidity measurement standards
·The only product in the industry that meets both the American Breweries Association (ASBS) and European Breweries Association (EBC) turbidity testing standards
Excellent low turbidity measurement technology
·0-40 NTU low turbidity measurement complies with EPA GLI No.2 standard method
The 'Average' calculation function ensures the reliability of turbidity measurement results for lake water and river water with particulate matter
