Chemical processing, industrial water and wastewater applications can be challenging environments for a pH sensor. Chemicals from the process mix with the reference electrolyte solution, changing the chemistry and leading to erratic readings. Fortunately, our differential pH and ORP sensors feature buffered reference electrolyte (SDS-7050), which can be replaced or refilled when needed. Also compatible with other brands, including Hach* and Water Analytics*. Contains 500mL.
