The HI99171 is a portable, waterproof meter designed for use with leather and paper. It provides fast, accurate, direct pH measurements and features a multi-level LCD display with on-screen tutorial messages for calibration and set-up. The HI99171 utilizes a flat tip probe designed to optimize surface contact with the sample. pH measurement of papers and cartons is important, not only in the production phase, but also in the packaging phase. The food industry, for example, regularly performs pH compatibility tests.
