Product Description

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.

• Extends life of differential pH & ORP sensors: for use with SD7000, SD7420, and SD7500 sensor models
• Direct-fit Compatibility: Compatible with several popular Hach & Water Analytics 5-wire differential pH & ORP models
• One year limited warranty: We stand behind all our products with the Sensorex Guarantee
