Question
What is the difference between salt bridge kits, PN SB-P1SV and PN SB-P1SP?
Summary
Differential pH and salt bridge part numbers
Answer
SB-P1SV is the standard salt bridge used on any pHD or pHDsc sensors.  Some applications may expose these sensors wetted materials to potential failure due to chemical incompatibility.  The standard o-rings included with the SB-P1SV are Viton material.  When the Viton material is not chemically compatible with the chemicals in an application, the SB-P1SP using perfluroelastomer o-rings is available.

PN SB-P1SV - Salt Bridge for pHD sc and pHD, PEEK Body and Kynar (PVDF) Outer Junction for PEEK Sensor with Viton O-rings

PN SB-P1SP - Salt Bridge for pHD sc and pHD, PEEK Body and Kynar (PVDF) Outer Junction for PEEK Sensor with perfluoroelastomer O-rings
