ZHC 1200 HELMEN®-Chalking Tester

Unique measuring instrument for quantitative determination of degree of chalking resulting from natural or artificial weathering of coatings
Direct measurement of the light-transmitting properties (luminous transmittance) of samples
The very first chalking tester with a touchscreen where you can immediately read off the degree of chalking
Superior sensitivity at the most crucial initial chalking stages and high accuracy also with regard to coloured pigments
Easy to handle
Reliable and objective measuring results
Reproducible, operator independent results

Features
Results can be reproduced impartially as no element of visual judgement applies, i.e. independent of the individual executing the test.
Superior sensitivity in the most crucial initial chalking stages compared to other approaches.
Increased accuracy in case of coatings showing chalking of coloured pigments compared to methods based on a contrasting substrate.
Up to 70 % relative chalking there is a linear relationship between the measured value and the quantity of loosely adhering pigments.
Direct checking of the light transmitting properties.
