Inline turbidimeter

Sigrist's AquaScat WTM turbidimeter offers maintenance-free inline turbidity measurement. The WTM model features contactless measurement, using a 'free-falling' stream together with programmable, automatic calibration. The AquaScat WTM has a wide measuring range from 0 to 4000 FNU covering all applications - from highly turbid raw river water, to optimally filtered pure water with 0.015 FNU. For normal measurement there is no need for a de-aeration tank, as the WTM model has an electronic, built-in bubble trap. This feature is sufficient for occasional bubbles. With an integral display and operating panel the AquaScat is fast and easy to install.

The AquaScat range includes a simpler HT model and a special P version for pressurised systems. The AquaScat HT is an economical model designed for applications with high turbidity and lower resolution, such as raw water. This version features manual calibration using a device with a solid reference. As with the WMT, the HT uses the maintenance-free, free-falling stream technology. The AquaScat P has a closed flow cell for measurement under pressure. This offers advantages when measuring turbidity in gas saturated water which is susceptible to bubble formation as pressure is relieved. As with the HT version, calibration is achieved using a device with a solid reference.
