HANNA – HI2550

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

The HI2550 is a rugged and highly accurate multiparameter benchtop meter. Offering two input channels, this meter is able to measure up to seven parameters including pH, ORP, ISE, EC, TDS, 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 HI2550 offers many features including five-point pH calibration, auto ranging EC and TDS measurements, data logging, comprehensive GLP data, and PC connectivity via USB to provide users with a simple way to organize and manage their data.
