Horiba Conductivity Meter Kit (EC220K)
It’s the newest generation of Waterproof handheld meters from Horiba that measure pH / Conductivity / mV (ORP) / TDS / Salinity / Resistivity. This comes with:
If are you're looking to measure two parameters simultaneously (pH / Conductivity - also ORP/TDS/Salinity/Resistivity with additional electrodes) then this is right for you. The meter itself is very durable and the housing is IP67 waterproof, non-slip, shock & scratch resistant.
Compared to the lower model (PC210), the PC220 has larger memory, a real-time clock, date/time stamp and also PC connection.
Summary: The PC220 is a double channel multi-parameter suitable for measuring pH, Conductivity, ORP, TDS, Salnity and Resistivity.
