The Blanko is a portable optical meter designed to measure sludge blanket and fluff level in clarifiers and thickeners in water and wastewater plants, as well as in other facilities.

The Blanko is able to store up to 250 measurements as a graphical profile, each with information about time, date and location that may be named by the user. Each profile also contains data about blanket and fluff levels that apply for the specific measurement. The sensor is made of high quality 316 stainless steel.

The Blanko is delivered in a practical briefcase. It is only supposed to be used in combination with the portable central unit, the Multitracker.
