Specifications
Measurement Method
The turbidity analyzer consists of a light source, a sample cell, and a light detector (photo detector). Incident light is scattered by the particles in the sample, and the scattered light is measured by the detector. The amount of scattering depends on the amount of material in the sample, the wavelength of light used and the size and composition of the suspended particles. The analyzer uses a long life near infrared LED (880 nm) and the 90° scattered light method which complies with DIN ISO 7027 or EPA method 180.1. An automated mechanical wiper is to remain surface clean and remove air bubbles of the optical window in order to maximize the accuracy and minimize the maintenance requirement.

Installation
Submersible, flow through, pipe insertion
