HI-901W Automatic Titration System for wine

The wine titrator complements our wide range of products dedicated to efficient and accurate laboratory analysis. The HI-901W potentiometric titrator can perform acid/base, redox (ORP), complexometric, precipitation, non-aqueous, argentometric, and ion selective titrations.

The powerful titrator dispenses the titrant, detects the endpoint, and performs all necessary calculations and graphs automatically. In addition to titration mode, the HI-901W also operates as a fully functional pH, mV/ORP, and ion selective electrode (ISE) meter.

The 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.

Titrator capabilities

• Dynamic titrant dosing – Dynamic dosing allows for timely and accurate 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 precise doses near the titration endpoint.
• Equivalence endpoint detection – 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 stabilises before providing the next titrant dose. This ensures reliable measurement values throughout the length of a titration.

Optimised for wine

Supplied with a full suite of standard wine methods, the Wine Titrator is optimised for winemakers. Packages are designed so that you’ll have everything you need to produce quality wine. Our preloaded packages include the following methods:

• Titratable Acidity – Acid/Base Titration (pH)
• Free SO₂ (Ripper) – Redox titration (ORP) )
• Total SO₂ (Ripper) – Redox Titration (ORP) )
• Free SO₂ (AO) – Acid/Base titration (pH) )
• Total SO₂ (AO) – Acid/Base titration (pH) )
• Volatile Acid – Acid/Base titration (pH) )
• YAN (formal number) – Acid/Base titration (pH) )
• Reducing Sugar – Redox titration (ORP) )

Burettes and dosing system

Exchangeable burette system – 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 HI-901W comes standard with a 25ml burette but may be equipped with a 5ml, 10ml, or 50ml burette.

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

Methods of analysis

• Customisable methods – The HI-901W can store up to 100 user-defined or standard titration methods. Each method may be customised and optimised for performance based on application and user requirements.
• Titration method support – Onsite installation, training, and customisation is available from one of our titration specialists here at Hanna. Hanna also offers continued support for any questions you may have.

Data and storage

• Customisable titration reports – each titration report is fully customisable so users can ensure they are storing and filing the appropriate data required for their application and procedures.
• Effortless data transfer – Data can easily be transferred to a USB flash drive or PC with the Hanna HI-900PC application software.

Connectivity and functionality

• Multifunctional and four working modes – The HI-901W functions as a titrator, pH meter, mV/ORP meter, and ISE meter.
• 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.
