The SPR-512 is a portable, multi-parameter digital meter designed to measure conductivity, total dissolved solids (TDS), and salinity in water and aqueous solutions. It features automatic temperature compensation (ATC) for accurate readings across varying conditions and includes a large LCD display with intuitive controls. While the standard SPR-512 also supports pH measurement, this version excludes the pH functionality.
This meter is ideal for environmental monitoring, water treatment, aquaculture, hydroponics, and laboratory use where conductivity-based parameters are essential.
