Digital Dissolved Oxygen Analyzer pH Controller Online Orp pH Meter

タイトルまたは説明

1. Product introduction

Online PH meter JC-PH***0 is a new generation of intelligent water quality detector. It has the characteristics of Chinese menu operation, high stability, excellent repeatability, multi-function, etc. It can accurately measure the pH value, oxidation-reduction potential (ORP) and temperature value in the solution. Widely used in: environmental protection, sewage treatment, thermal power, aquaculture, food processing, printing, metallurgy, fermentation, chemical industry, tap water and other solutions on-line detection of PH value.
