EC/TDS Starter Benchtop Meter
HI2630 and HI2631 enables fast, accurate measurements utilizing the Hanna Instruments® HI763100 digital conductivity electrode with an integral temperature sensor. The probe has a unique serial number and, once connected, is automatically identified by the meter. Both meters measure conductivity (EC) and TDS while HI2631 adds salinity measurement and calibration along with data logging capabilities. The intuitive design simplifies configuration, calibration, measurement, data logging and transfer (to a USB thumb drive or computer). HI2630 and HI2631 benchtop meters offer a Basic Mode that streamlines measurement configuration and is useful for routine applications. Additionally, HI2631 can be used in Standard Operating Mode, where all features and capabilities are enabled
- Automatic parameter recognition
- Choice of measurement unit:
- Conductivity: μS/cm, mS/cm
