Hanna Research Grade Conductivity/TDS Meter with USP EC/TDS/Resistivity/Salinity and Temperature, 230V - HI4321-01

HI4321-02 Research Grade Conductivity/TDS Meter with USP EC/TDS/Resistivity/Salinity and Temperature, 230V by Hanna Instruments

HI 4321 is a research-grade EC/Resistivity/TDS/Salinity benchtop meter with a large, color, graphic LCD with backlight, capable of millesimal measuring resolution of conductivity with an extended range from 0.001 µS/cm to 1 S/cm.

Conductivity is fully customizable and include: temperature compensation coefficient, temperature reference, selectable compensation method, linear, natural water and no compensation, adjustable cell constant and TDS factor.

All ranges of conductivity, resistivity and TDS feature autorange or users can select the unit to measure manually. Three salinity scales are available: natural sea water, practical salinity and %.

HI 4321 can be used to perform all 3 stages of USP <645> method required for conductivity measurement of pure and ultra pure water. The instrument provides clear directions on how to perform each testing stage and automatically monitors the temperature, conductivity and stability during testing and determines whether a sample is within USP limits.

This instrument is equipped with auto standard recognition and can support custom calibration solutions. Up to a four point calibration can be obtained for enhanced accuracy over an extended measuring range.

The enhanced warning system is in place to alert users when measuring outside the calibration range. This system will also remind the user when a new calibration is due.

Features also include real-time graphic displays and on-screen GLP data. Fully customizable instrument and parameters via setup screens. On-board contextual help can be accessed from any mode simply by pressing the HELP button.

Up to 10 profiles can be saved and recalled eliminating the need to reconfigure each time when a different electrode is used.

Three selectable logging modes are available: Automatic, Manual and AutoHold logging. Up to 100 logging lots with 10,000 records per lot can be stored for automatic or manual modes along with up to 200 USP reports.

All features are available in English, Italian, Portuguese and Spanish. Connect to a PC via the USB or RS232 ports, with the use of HI 92000 Windows® compatible software.
