• TSS range: 0 to 50,000 mg/L*
• High stability, high precision, and excellent repeatability (±2%)
• Communication: MODBUS RTU (RS-485)

*The measurement range NTU or TSS must be chosen at the time of order. 

Few sensors can boast the versatility, low maintenance, and industrial-strength that the TT-NTU-DSS-7833D-SC turbidity sensor has to offer. The sensor body is made of 316L stainless steel, which is corrosion-resistant and extremely durable. A titanium version is also available for seawater applications or environments with high levels of corrosion.

The IP68 waterproof design can be fully immersed for continuous turbidity measurement in a wide variety of industrial applications including water quality monitoring, municipal water, industrial process water, cooling water, activated carbon filter effluent, and membrane filtration effluent just to name a few.

The TT-NTU-DSS-7833D-SC comes complete with a fully automatic sensor wiper. This self-cleaning function effectively prevents solid particles from building up on the lens, not only reducing the maintenance requirement but greatly improving measurement accuracy over the long term. The self-cleaning function can be set according to the application requirements to provide stable data and reliable performance, while the built-in diagnostic functions greatly simplify the sensor management.

The principle of the Turtle Tough Smart Digital Turbidity sensor is based on the combined infrared absorption and scattered light method. The ISO7027 method can be used to continuously and accurately determine the turbidity value. According to ISO7027 infrared double-scattering light technology is not affected by chromaticity to determine the sludge concentration value.
