HM Digital SP-C4 Replacement TDS Sensor for COM-360 | OEM Drop-In Replacement
HM Digital SP-C4 Replacement TDS Sensor for COM-360 Restore your HM Digital COM-360 to factory-spec accuracy with the SP-C4 OEM replacement TDS sensor . Designed as a direct drop-in replacement, the SP-C4 delivers reliable total dissolved solids (TDS) measurement without the cost of replacing your entire meter — keeping your water quality monitoring operation running without interruption.
Key Features
Direct OEM replacement — engineered specifically for the HM Digital COM-360 TDS/EC meter
Accurate TDS measurement — maintains the precision your COM-360 was calibrated to deliver
Plug-and-play installation — connects directly to the COM-360 with no recalibration required
Durable probe construction — built to withstand continuous immersion in water quality monitoring environments
Why Replace Your Sensor? Over time, TDS sensors accumulate mineral scale, biofilm, and electrode wear that degrade measurement accuracy. Swapping in a fresh SP-C4 sensor is the most cost-effective way to restore your COM-360 to peak performance — extending the life of your instrument and maintaining data integrity for your water quality program.
