The turbidimeter TRM-100 is a compact device for measuring turbidity in liquids. The "turbidity" is measured using the scattered light method (angle 90 degrees) for the turbidity range of < 1,000 FNU (Formazine Nephelometric Units) and the transmitted light method (angle 0 degrees) for the turbidity ranges > 1,000 FAU (Formazine Attenuation Units).

QFS-55
Teflon float switch in rod design
The float switch combination is built with float switches of the QFS-50 and QFS-60 series. This makes it possible to control a level in a simple way.
