Pfund Black & White Cryptometer<br />
a simple and rapid test method to determine opacity in<br />
terms of hiding and spreading powers. This precision<br />
instrument is suitable for production and quality control<br />
purposes, particularly when product specifi cations are<br />
based on the evaluation of wet fi lms instead of dry coatings.<br />
The measurement is made simply by searching the position<br />
on the engraved scale where the wet coating, trapped<br />
between the wedged top plate and the scale, perfectly hides<br />
the background.<br />
Features<br />
Supplied with 2 top plates & case<br />
2 top plates combinations:<br />
K=0.04 + K=0.08, or K=0.02 + K=0.07, with optional<br />
K=0.035a simple and rapid test method to determine<br />
opacity in terms of hiding and spreading powers. This<br />
precision instrument is suitable for production and quality<br />
control purposes, particularly when product specifi cations<br />
are based on the evaluation of wet fi lms instead of dry<br />
coatings.<br />
