Description

Convenient design verified by work experience in many laboratories, extremely easy operation, (only one touch button and automatic switching of measuring ranges) advanced electronics and optics, wide dynamic range with excellent stability and reliability – are attributes coditioning this hazemeter for everyday usage everywhere, where the purity (haze) of liquid samples needs to be regularly examined.
Inspection, quality control, process optimisation in food manufacturing, drinking and waste water and biotechnology.
Immersion technique with water bath, automatic bottle rotation and digital signal processing enables measuring of samples not only in standard cuvettes but directly in sealed bottles of various diameter as well.

Measurement of small volume samples in chemical tubes
Kinetics measurement of haze development
Turbidimetric titration………….

Dual-angle hazemeter COLORTURB-MZN2012 offers qualitatively entirely new possibilities compared to common one-angle nephelometers or turbidimeters. Intensity of light scattered at specific angle depends not only on the concentration of haze particles but also on their size. The comparison of haze values in both independant measuring channels so provides information regarding the haze particle size.
