Karl Fischer Coulometric Titrator HI934-02

The HI934 is a Karl Fischer coulometric titrator with high accuracy, great flexibility and repeatability.
The titrator is designed to perform titrations for a variety of applications, allowing the user to obtain both good results and high-speed analysis. The HI934 analyzes for water content ranging from 1 ppm to 5%. This powerful titrator effectively monitors the KF reaction, detects the endpoint, and performs all necessary calculations and graphing.

Coulometric Reagent System

Precision Iodine Generation
Hanna's dosing algorithm allows for an extremely small amount
of iodine necessary for the Karl Fischer reaction to be generated
electrolytically using a pulsed current up to 400 mA delivering titrant
accurately and precisely.

Titration and Solvent System

Chemically Resistant Titration Vessel and Tubing
The glass titration cell and PTFE tubing is designed to withstand the
harsh solvents and reagents involved in Karl Fischer reactions.
Sealed Solvent System
Ground glass joints completely seal the glass titration cell minimizing
exposure to ambient humidity, keeping the system dry, and reducing
reagent consumption while saving time between titrations. Solvent
may be exchanged in a matter of seconds with a quick fitting adjustment.
Molecular Sieve Desiccant
High efficiency molecular sieve desiccant helps maintain low and
stable drift rates within the titration cell while preventing the ingress
of ambient humidity into the sealed solvent system.
Digital built-in stirrer
Automatic, integrated magnetic stirrer adjustable from 200-2000
RPM with optical feedback for automatic speed control.

Titrator Capabilities

Dynamic Titrant Dosing
The titration speed feature allows for timely and accurate titration
results by relating the amount of iodine generated to the mV response
from the Karl Fischer reaction.
Drift Rate Compensation
The HI934 automatically adjusts the titration calculation to account
for the effects of any ambient humidity entering the titration cell. This
provides a more accurate result by correcting for water not present in
the actual sample.
Titration Results Averaging
Successive results from a titration method may be averaged with
recording of the standard deviation.
Selectable Endpoint Criteria
The HI934 employs a dual platinum pin electrode for bivoltammetric
endpoint determination. Users may choose termination criteria based
on mV stability times or drift rates.
Multistage Cell Preparation
A pre-titration stage eliminates residual water present in the solvent
and the cell, providing a reliable baseline start to analysis. Standby
mode then keeps the solvent dry between titrations and when the
titrator is not in use.

Interface & Display

Detailed Titration Graphs
A real-time titration curve can be displayed during each titration; this
feature is useful when new methods are tested or when a procedure
requires optimization.
Interactive Color Display
A large, color LCD screen clearly shows the chosen titration method
along with results, units, drift rate, and mV value.

Simple and Quick Navigation

Virtual key selections present on the display allow for simple and quick
navigation between screens and menus without getting lost in a nest
of information.

Data & Storage

Customizable Titration Reports
Each titration report is fully customizable so users can ensure they are storing and filing the appropriate data required for their application and procedures.
Flexible GLP Management
All necessary GLP (Good Laboratory Practice) information can be recorded with each sample including: sample identification, company and operator name, date, time, electrode ID codes, and calibration information.
Effortless Data Transfer
Data can easily be transferred to a USB flash drive or PC with the Hanna HI900PC application software. The USB port allows for the transfer of titration methods, titration reports, and software upgrades via USB flash drive.
Methods of Analysis
Customizable Methods
The HI934 can store up to 100 user-defined or standard titration methods. Each method may be customized and optimized for performance based on application and user requirements.
Titration Method Support
Onsite installation, training, and customization is available from one of our Applications or Service experts. Hanna offers continued support via phone or webinar for any questions you might have along the way.
Adaptable Standard Methods
Our technical experts can program and customize standard methods developed by such affiliations as ISO, ASTM, AOAC, AOCS, EPA, and more directly onto your titrator. Ask our Sales Consultants which standard methods are possible with our HI934 Karl Fischer system.
Connectivity and Functionality
Configurable Balance Interface
Sample size may be automatically entered from any laboratory analytical balance with a RS232 serial output saving time and labor.
Multiple Peripherals
Users can print reports directly from the titrator using a standard parallel printer. An external monitor and keyboard may be attached for added versatility, as well as an analytical balance for automatic sample mass entry for titrations.
