Accurately measure turbidity with this portable device
The TB350 (photo) is said to be the most advanced portable turbidimeter on the market. It uses Multipath 90° BLAC (backscattered light absorbing cavity), a new, patented sensor technology. Two detectors are arranged at 90-deg, which ensures a purely nephelometric measuring principle. During the turbidity measurement, two different path lengths of the incident light beam through the sample are cleverly exploited. With the novel BLAC technology, the light-absorbing trap almost completely eliminates unwanted stray light and provides extremely accurate results for low turbidities down to 0.01 NTU. The TB350 has the accuracy of a laboratory measurement, but in a portable instrument. Highest accuracy is guaranteed in the lowest turbidity range from 0.01 NTU, while maintaining the precision level in the highest turbidity range up to 4,000 NTU. The TB350 is available as an infrared or white light version, is compliant with valid ISO 7027 and U.S. EPA (pending) regulations and standards. Hall C1, Stand 329 — Tintometer GmbH, Dortmund, Germany
