The HI98131 GroLine Combo offers high accuracy pH, EC (conductivity), TDS (total dissolved solids), and temperature
measurements in a rugged, waterproof casing that floats.
The GroLine Combo features a replaceable pH electrode with extendable cloth junction as well as an EC/TDS graphite electrode.
The renewable cloth junction provides an extended electrode life and the replaceable pH cartridge means that this tester does not
need to be thrown away when the pH sensor is exhausted.
The EC/TDS conversion factor is userselectable, as well as the temperature compensation coefficient (β).
