HI5522 Research Grade Meter pH/ORP/ISE and EC/TDS/Resistivity/Salinity and Temperature The HI5522 is an advanced research grade benchtop pH/ORP/ISE and EC/TDS/Salinity/Resistivity meter that is completely customizable with a large color LCD, capacitive touch keys, and USB port for computer connectivity. The HI5522 is a two-channel meter that allows for simultaneous measure of pH, ORP, or ISE on one channel and EC, TDS, Salinity, or Resistivity on the other. Channel one has a BNC connection for use with the expansive line of pH, ORP, and ISE electrodes that Hanna Instruments offers. The meter is supplied with the HI1131B glass body, double junction, combination pH electrode that operates over a wide temperature range from 0 to 100°C. All readings are automatically compensated for temperature variations with the separate HI7662-T temperature probe or from the built-in temperature sensor of the conductivity probe on Channel two. The HI5522 is supplied with the HI76312 four-ring conductivity probe that operates over a wide range from 0.000 μS/cm to 1000.0 mS/cm*. The meter can be set to autoranging in which the meter chooses the appropriate conductivity range from seven ranges or fixed range in which the meter will only display reading in μS/cm or mS/cm. All readings are automatically compensated for temperature variations with a built in temperature sensor. The temperature correction coefficient is adjustable from 0.00 to 10.00 %/°C. As a pH meter the HI5522 can be calibrated up to five points with a choice of eight pre-programmed buffers or five custom buffers. The HI5522 features Hanna’s exclusive CAL Check™ to alert the user of potential problems during the pH calibration process. Indicators displayed during calibration include “Electrode Dirty/Broken” and “Buffer Contaminated.” The overall probe condition based on the offset and slope characteristic of the electrode is displayed as a percentage after calibration is complete. 3 ISE 3.6 | www.hannainst.com benchtop
