HI-901W Automatic Titration System for wine
The HI-901W Wine titrator is perfect for winemakers who need accurate results, ease-of-use, and the ability to expand the system as their analytical needs grow.
It comes preloaded with methods for wine analysis, and with Hanna, you get the support you need to run them perfectly in your lab.
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.
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.

|Yeast available nitrogen (YAN) titration solution|
|HI-70456||Sodium hydroxide solution (0.1N), 1L|
|HI-70457||Sodium hydroxide solution (1N), 1L|
|Titratable acidity titration solution|
|HI-70456||Sodium hydroxide solution (0.1N,) 1L|
|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 0.2-0.4 g/L. Any level higher could indicate microbial involvement and potential spoilage. Solutions available:|
