Easily and inexpensively extend the life of your Hach differential sensors. By periodically replacing the salt bridge and standard cell solution, you can maximize the life of your Hach Differential Sensors. For optimum performance, Hach recommends that differential sensor salt bridges be replaced every 6 months.
The double junction salt bridge on all Hach pHDTM Differential pH / ORP Sensors is field-replaceable, and includes a FKM/FPM O-ring. Salt bridges are shipped in a salt solution to prevent dehydration / dry-out and can be stored in the shipping solution until needed. Salt bridges are available in a variety of materials and pre-packaged quantities.
