Combination TDS & EC Meter

The Combination TDS & EC Meter provides both total dissolved solids in ppm and electrical conductivity in µS/cm or mS/cm on a single device, with a third readout for water temperature. This dual measurement capability is particularly valuable for aquarists who use EC as the primary unit for remineralising RO water (especially for shrimp and planted tanks) while also communicating TDS to other hobbyists.

The automatic temperature compensation corrects EC readings to a 25°C reference standard, ensuring comparability across readings taken at different water temperatures. The ATC range covers 0–80°C, accommodating everything from cold-water fish tanks to hot RO membrane output.

The large three-line display shows all three values simultaneously, enabling immediate assessment of water chemistry without switching between modes. The probe is waterproof to IP67 and can withstand brief full immersion.
