The HI-99171 portable pH meter together with a HI-14143 combination pH electrode (when immersed in a drop of water on the surface of the sample), can determine the pH of the surface with high accuracy and repeatability without the requirement of sample destruction.
During production of cartons and paper used for food packaging, pH measurements provide a useful gauge of product compatibility. pH of a paper is usually considered one of the most reliable indices of the permanence of a paper.
Conservators of historical documents (some of which are very valuable or irreplaceable) require a convenient non-destructive method to determine pH.
Leather technicians rely on a pH determination to optimize dyes, coating, and softening agents in order to preserve the fibre structure and prevent damage to leather. Leather is acidic. Its pH is measured at between 4.5 and 5.0. Surface pH measurements provide a non-destructive means to meet specifications and optimize product quality.
