Hanna Instruments HI-7631233 Platinum four-ring EC and resistivity probe
The HI-7631233 is a four-ring conductivity/resistivity/TDS/salinity probe. The electrolytic conductivity (EC) reading from the HI-7631233 sensor can be used to calculate Total Dissolved Solids (TDS), Resistivity, and Salinity (PSU, ppt, or %).
HI-7631233 Platinum Four-Ring EC and Resistivity Probe
Recommended for a wide range of industrial process water applications, HI-7631233 provides stable measurements over a wide measurement range and does not require frequent calibrations. An integral temperature sensor measures the process temperature and adjusts the measured conductivity to a reference temperature by applying specialised compensation algorithms.
This electrode has a range from 0 to 1000 mS/cm and is supplied with a DIN connection and 1m cable
The HI-7631233 probe is compatible with the HI-6000 multiparameter system from Hanna Instruments. This modular multimeter allows you to plug-and-play modules for pH, ORP, ISE, EC and DO, providing full flexibility in measurement while saving benchtop space for laboratory and research environments.
