The 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.

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

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 procedures.
• Effortless data transfer
 Data can easily be transferred 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 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.

Methods of analysis

• Customizable methods
The HI901W 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.

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
Equivalence 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 type
    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.
