HANNA – HI3512

Professional Multiparameter Benchtop pH/mV/ISE and EC/TDS/Resistivity/Salinity Meter

The HI3512 is a professional, accurate multiparameter benchtop meter. Offering two input channels, this meter is able to measure up to eight parameters including pH, ORP, ISE, EC, TDS, resistivity, salinity, and temperature. The meter comes with Hanna’s HI1131B glass pH electrode, HI76310 four-ring conductivity probe, and a temperature probe to allow for automatic temperature compensation. The HI3512 offers many features including CAL Check, five-point pH and ISE calibration, autoranging EC, TDS, and resistivity measurements, data logging, comprehensive GLP data, and PC connectivity via USB to provide users with a simple way to organize and manage their data.
