Hanna Instruments HI5521 Laboratory Research Grade Benchtop pH/mV and EC/TDS/Salinity/Resistivity Meter

The HI5521 is a benchtop, sophisticated research-grade pH/mV/EC/TDS/Salinity/Resistivity meter featuring capacitive touch keys, a big color LCD, and a USB connector for connecting to a computer.

The HI5521 is packed with capabilities, such as data logging, alarm limits, full GLP, and many more, yet it still manages to be simple to use thanks to dedicated keys for normal operation and virtual keys that lead the user through setup options.

The HI5521’s unique Hanna Instruments CAL CheckTM feature, which warns the user of potential issues during calibration and indicates whether the buffer is contaminated or the probe has to be cleaned, ensures the accuracy of pH measurements.
