Frequently Asked Questions

Who should use Sentia™?

Sentia™ is designed for winemakers and other winery personnel that want to measure free sulfur dioxide, malic acid and glucose in red and white wine. No specialist skills are required.

What does Sentia™ measure?

Sentia™ measures free sulfur dioxide, malic acid and glucose in red and white wine. We are currently working on more tests including fructose, titratable acidity, acetic acid and more.

In which countries can I use Sentia™?

Sentia™ has regulatory approval in Australia, New Zealand, Canada, Europe (EU) and the United States of America.

Where can I use Sentia™?

Sentia™ is truly portable. It has the same form factor as a typical smartphone so it will even fit in your pocket. You can use Sentia™ wherever you need a test result.

Is sample preparation required?

No sample preparation is required for free SO2 and glucose methods. Simply apply a drop of red or white wine to the test strip when prompted by the Sentia™ Analyzer.

Malic acid requires a simple pre-dilution with Sentia™ malic acid buffer.

How long does it take to get a measurement?

After you apply your wine sample, Sentia™ delivers a result in less than a minute.

Does Sentia™ store past results?

Yes. Sentia™ stores up to 1000 results in its memory and can export those results over Wi-Fi.

Can I analyze my past results?

You can export your past results from Sentia™ over Wi-Fi to your computer in CSV format. You can then import the data into a spreadsheet in order to analyze, sort and filter your results. 

Do I need to be connected to Wi-Fi to get a result?

Sentia™ is able to run tests without a Wi-Fi connection. You will need to have a Wi-Fi connection when you first use Sentia™ so that you can download calibration data from the internet. After that, you will need to connect once every three months or so to download the latest calibration data for new strips made at our production facility. However, we recommend that you stay connected to Wi-Fi as often as possible so that your software can be upgraded when a new version is available.

Can I only use Sentia™ to measure wine?

Sentia™ has been designed for the testing of red and white wine. If you want to test another beverage, we recommend that you cross-check the results you get from Sentia™ with another independent method.

Do I need to provide batteries?

Sentia™ contains a fully enclosed rechargeable battery and comes with a power adaptor.

How long is the battery life?

Sentia™ can run at least 100 free SO₂ tests between battery charges. Charging the battery is as simple as plugging in the power adaptor (provided).

Will there be upgrades to the software in future?

Sentia™ will automatically check for software upgrades whenever it is connected to the internet (via Wi-Fi). If an upgrade is available, Sentia™ will perform the upgrade (after confirming with you that it is a good time to do so).
