TRM-100
Turbidimeter (0...1.000 FNU or 500...4.000 FAU)
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).
