The AquaScat measures turbidity of potable water according to IEC 27027 in a free-falling water stream. This contactless design eliminates window foiling and minimizes servicing which is especially of importance with the version HT for high turbidity. Calibration check is performed with a calibration unit with a glass reference to be mounted when performing the check.
