The HI5522 is an advanced research grade benchtop pH/mV/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 rich in features including data logging, alarm limits, comprehensive GLP, and many more while retaining simplicity in use with both dedicated key for routine operation and virtual keys that guide the user through setup options. The HI5522 ensures confidence in pH measurements with the exclusive Hanna Instruments CAL Check™ feature that alerts the user to potential problems during calibration including if the buffer is contaminated or the probe needs to be cleaned.
- Capacitive Touch Keypad
- Two independent channels. Supplied with HI1131 pH electrode, HI7662-T temperature probe, HI76312 conductivity probe
- ISE choice of concentration units and incremental methods
Features at-a-glance
Highly Customizable User Interface – The user interface of the HI5522 allows the user to show measurements in various modes: basic measurement with or without GLP information, real-time graphing, and logging data. Calibration stability criteria can be adjusted from fast, moderate, and accurate. Programmable alarm limits can be set to inside or outside allowable limits.
Color Graphic LCD – The HI5522 features a color graphic LCD with on-screen help, graphic, and custom color configurations. The display allows for real-time graphing and the use of virtual keys provide for an intuitive user interface.
Capacitive Touch – The HI5522 features sensitive capacitive touch buttons for accurate keystrokes when navigating menus and screens. There are four dedicated keys that are used for routine operations including calibration and switching measurement modes and four virtual keys that change based upon use. The capacitive touch technology ensures the buttons never get clogged with sample residue.
Four Ring Conductivity Probe – Conductivity readings are performed with the HI76312 four-ring conductivity probe that has a built in temperature sensor for automatic temperature correction. The four rings are made with platinum and the body of the electrode is made of Polyetherimide (PEI) plastic that is resistant to many harsh chemicals. The four-ring design allows for this probe to be used over a wide range of measurements.
Choice of Calibration – Automatic buffer recognition, semiautomatic, and direct manual entry pH calibration options are available for calibrating up to five points, from a selection of eight standard buffers and up to five custom buffers. For the conductivity channel the calibration can be set to automatic standard recognition or user entry along with a choice of single or multi-point. Calibration can be performed up to four points when multi-point is selected.
CAL Check™ – CAL Check™ alerts users to potential problems during the calibration of the pH electrode. Indicators include “Electrode Dirty/Broken,” “Buffer Contaminated,” electrode response timeand the overall probe condition as a percentage that is based on the offset and slope characteristics.
GLP Data – HI5522 includes a GLP Feature thatallows users to view calibration data and calibration expiration information at the touch of a key. Calibration data include date, time, standards used for calibration.
Data Logging – Three selectable logging modes are available on the HI5522 : automatic, manual, and AutoHold logging. Automatic and manual logs up to 100 lots with 50,000 records max/lot, with up to 100,000 total data points. Automatic logging features the option to save data according to sampling period and interval.
Data Transfer – Data can be transferred to a PC with USB cable and HI92000 software (both sold separately).
Contextual Help – Contextual help is always available through a dedicated “HELP” key. Clear tutorial messages and directions are available on-screen to quickly and easily guide users through setup and calibration. The help information displayed is relative to the setting/option being viewed.
