Liquid hydrogen peroxyde generator WP10.1

for water treatmentindustrialfor disinfection

Overview
The German-made WP10.1 hydrogen peroxide sensor uses a membrane-covered amperometric 2-electrode system to measure hydrogen peroxide (H₂O₂) across multiple ranges up to 200000 ppm. Designed for industrial water treatment including seawater, it operates in a pH range of 2–11 and offers mechanical durability and high resistance to surfactants and chemicals. The sensor includes automatic temperature compensation and is available with multiple flexible output options. With IP65/IP68 protection and calibration via on-device analytical determination, no zero-point adjustment is required.
