The ST-730 series of turbidity probes are designed for a wide range of turbidity monitoring in various applications. Each device is configured with a specific scale for NTU detection, ranging from as low as 1NTU to as high as 10,000 NTU. These series of probes are more robust and tolerant to fouling, particulate and air bubble challenges compared to alternative turbidity meters designed for relatively clean water applications. The ST-730 series of probes also offer desired resolution and accuracy in high turbidity applications commonly using Suspended Solids Meters.
