Neptune Systems Conductivity Calibration Solution - 53000 Microsiemens

Keep your Neptune Systems conductivity probe calibrated with this single-use 53,000 µS reference solution. Formulated to match natural seawater at 35ppt salinity, it delivers the accuracy your reef tank demands. The convenient tear-open packet prevents contamination and ensures reliable readings every time. Calibrate every 3–6 months using RO/DI water between steps for optimal performance. Compatible with Neptune Systems Conductivity Probes and PM2 Module. For freshwater applications, use the 447 µS solution instead.
