Hanna HI99171 Leather and Paper pH Portable Meter

Hanna HI99171 Leather and Paper pH Portable Meter – Precision pH Measurement for Tanning, Pulp, and Specialty Paper Industries

The Hanna HI99171 Leather and Paper pH Portable Meter is a rugged, portable pH and temperature meter specially designed for the leather processing and paper manufacturing industries. This HACCP-compliant instrument ensures fast, accurate pH measurements in low-moisture, semi-solid, or surface-level samples such as hides, skins, pulp, and specialty paper.

Paired with the HI1414D/50 pre-amplified pH electrode, this meter delivers consistent results even in harsh environments with high humidity, chemical exposure, or irregular surfaces. Whether used in quality control labs or on the production floor, the HI99171 offers a reliable way to monitor pH for process optimization, compliance, and product quality.
