Laboratory Research Grade Benchtop EC/TDS/Salinity/Resistivity Meter with ATC and Extended Range


The HI5321 is an advanced research grade benchtop EC/TDS/Salinity/Resistivity meter that is completely customizable with a large color LCD, capacitive touch keys, and USB port for computer connectivity. The HI5321 is rich in features including 4 point calibration, autoranging, 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.

•  Autoranging over a wide range from 0.000 μS/cm to 1000.0 mS/cm
•  Capacitive touch keypad
•  Preprogrammed with USP method

Features at-a-glance :

  Capacitive Touch
•  The HI5321 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.

  Choice of Calibration
•  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.

  Color Graphic LCD
•  The HI5321 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.

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.

Data Logging
•  Three selectable logging modes are available on the HI5321: 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).

  Four Ring Conductivity Probe
•  All 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.

GLP Data
•  HI5321 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.

Highly Customizable User Interface
•  The user interface of the HI5321 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.
