Spectra Watermakers Salinity Probe Replacement Kit KIT-MPC-SP

Overview

KIT-MPC-SP is cataloged as a salinity-probe replacement kit. Its title does not identify the supplied probe generation or whether a daughter board is included.

Spectra’s probe guide says MPC 3000 controls require an MPC 5000 upgrade to use SP4. Existing MPC 5000 installations must also be checked by board revision; the kit name does not bypass those requirements.

Record the board’s A## or B## identifier and the installed probe number before selecting a replacement package.
