Introduction
Product Definition
The A68 hydrogen-rich water test pen (English identifier: a68-hydrogen-rich-water-test-pen) is a portable multi-parameter water quality test pen capable of simultaneously measuring pH, ORP oxidation-reduction potential, dissolved hydrogen concentration (H2), and temperature of water samples. It is primarily used for rapid on-site testing of hydrogen-rich water and related water quality.
Product Features
