Product information "HI901W-02 Automatic Titration System for Wine"

The HI901W Wine Titrator complements our wide range of products dedicated to efficient and accurate laboratory analysis. The HI901W potentiometric titrator can perform acid/base, redox (ORP), complexometric, precipitation, non-aqueous, argentometric, and ion selective titrations.

This powerful titrator dispenses the titrant, detects the endpoint, and performs all necessary calculations and graphs automatically. In addition to titration mode, the HI901W also operates as a fully functional pH, mV/ORP, and ion selective electrode (ISE) meter.

This titrator is supplied with standard wine methods or you can create your own. Methods (standard or user) can be easily transferred between titrators via USB flash drive or PC application.

 

Methods of analysis

Customizable methods

The HI901W can store up to 100 userdefined or standard titration methods. Each method may be customized and optimized for performance based on appliction 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 the phone for any questions you might have along the way.

Titrator Capabilitities

  • DYNAMIC TITRANT DOSING
  • EQUIVALENCE ENDPOINT DETECTION
  • MULTIPLE TITRATION TYPES
  • SIGNAL STABILITY TIMING
  • MULTIPLE BUREETE SIZES
  • PRECISION DOSING PUMP

 

DYNAMIC TITRANT DOSING

Dynamic dosing allows for timely and accurante titration results by relating the titrant volume dosed to the mV response from the titration reaction.  This provides for larger doses near the beginning of a titration and smaller, more presise doses near the titration endpoint.

EQUIVALANCE ENDPOINT DETECTION

Equivalance endpoint detection is critical in applications where fixed endpoints are not specified in standard methods.  This endpoint indicates where the MV response from the titration is greatest with respect to the volume of titrant dosed.

MULTIPLE TITRATION TYPES

Paired with the right electrode from our sensor line, our potentiometric titrator can perform acid/base, redox (ORP), complexometric, precipitation, non-aqueous, argentometric, and titrations with an ion selective electrode.

SIGNAL STABILITY TIMING

The signal stability feature monitors when the mV response of the titration reaction stabilizes before providing the next titrant dose.  This ensures reliable measurement values throughout the length of a titration.

 

Burettes and Dosing System

SIGNAL STABILITY TIMING

With Hanna's Clip-Lock burette, it only takes a few seconds to exchange titrants and reagents, preventing cross-contamination and saving time.

MULTIPLE BURETTE SIZES

The HI901W comes standard with a 25ml burette, but may be equipped with a 5ml, 10ml or 50ml burette.

PRECISION DOSING PUMP

Our unmatched 40,000 setp piston driven pump is capable of dosing extremely small and precise volumes of titrant or reagent. 

 

Data and 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 procedurers.

EFFORTLESS DATA TRANSFER

Data can easily be trasferred to a USB flash drive or PC with the Hanna HI900PC application software.

 

Connectivity and Functionality

MULTIFUNCTIONAL WITH FOUR WORKING MODES

The HI901W functions as a titrator, pH meter, mV(ORP Meter), and ISE Meter.

MULTIPLE CONNECTIONS (HI901C2 ONLY)

The titrator offers device support for two analog boards, which allows two electrodes and two stirrers to be simultaneously connected to one unit.

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 titrators.

Volatile Acidity (VA)

Acetic acid is commonly formed during yeast growth in the early stages of fermentation.  The rate and amount of acetic acid formed is partially dependent on the pH, sugar levels, available nitrogen, and temperature of the system.  Typical VA levels post-fermentation range from 0.2-0.4g/L.  Any level higher could indicate microbial involvement and potential spoilage.
