HI-2641 benchtop meter enables fast, accurate measurements utilising the Hanna Instruments digital electrode / probe for dissolved oxygen. Each digital electrode / probe has a unique serial number and the parameter that it measures is automatically identified by the meter.
Once connected, the single sensor or sensors are ready to measure the parameter along with temperature. The HI-2641 measures dissolved oxygen in ppm and % saturation while adding data logging capabilities.
The intuitive design simplifies configuration, calibration, measurement, data logging and transfer of data to a USB or computer. The benchtop meter offers a Basic Mode that streamlines measurement configuration and is useful for routine applications. Additionally, HI-2641 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.
