HI-2631 Conductivity Benchtop meter with Data Logging
HI-2631 benchtop meter enables fast, accurate measurements utilising the Hanna Instruments digital electrode for conductivity (HI-763100) which includes an integral temperature sensor. Each digital electrode has a unique serial number and the parameter that it measures is automatically identified by the meter.
The 2631 measures conductivity and TDS while adding salinity measurement and calibration along with data logging capabilities.
The intuitive design simplifies configuration, calibration, measurement, data logging and transfer of data to a USB thumb drive or computer.
The benchtop meter offers a Basic Mode that streamlines measurement configuration and is useful for routine applications. Additionally, the HI-2631 can be used in Standard Operating Mode, where all features and capabilities are enabled.
The meter has a large display with capacitive keys which features a 5.5” (14 cm) LCD. The large display provides a 130 ° wide viewing angle.
