A new generation of intelligent water quality detector. It can accurately measure pH value, oxidation-reduction potential (ORP) and temperature in solution. It is widely used for on-line detection of pH value in solutions such as environmental protection, sewage treatment, thermal power, aquaculture, food processing, printing, metallurgy, pharmacy, fermentation, chemical industry and tap water.
