ZHC 1200 HELMEN®-Chalking tester
  • Unique measuring instrument for quantitative determination of the degree of chalking resulting from natural or artificial weathering of coatings using a specimen holder as well as direct measurement of the light-transmitting properties (luminous transmittance) of samples.
  • The very first chalking tester with a touchscreen, on which 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 results independent of the individual person.

 

Standard Delivery
  • 1 chalking tester
  • 1 specimen holder
  • 2 plastic spatulas
  • 2 batteries type AA
  • 2 rolls special adhesive tape with 1 adhesive tape roller
  • 1 instruction manual
  • 1 certificate of manufacturer
  • 1 carrying case

 

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.
