Labotronics Ratio Turbidimeter is an analytical instrument specifically designed for measuring the turbidity of liquid samples by employing a ratio turbidimetry technique. This method involves the measurement of scattered light at two different angles, typically 90 and 180 degrees, to enhance accuracy in turbidity readings. The instrument uses a dual detector system to minimize interferences and improve sensitivity, ensuring precise and reliable turbidity measurements. Our ratio turbidimeters are commonly employed in water treatment facilities, environmental monitoring, and industrial processes where accurate turbidity assessments are crucial for quality control and regulatory compliance.
