Product Details

PHS-8B handheld protable digital online PHS-8B ph/orp tester / transmitter

Introduction

PHS8B intelligent industrial PH transmitter is the intelligent industrial online analytical instrument. It can be connected to the high-impedance analog signal pH ORP electrode of many companies at home and abroad. It can be used to detect the pH, ORP value of the solution in chemical, petroleum, rubber, paper, tobacco, alcohol, sugar, food, mining, smelting, iron and steel, power generation, pharmaceuticals, water treatment and other industries.
