The power of a lab in the palm of your hand.

The Sentia™ Analyzer measures free SO₂ and Malic Acid in post-fermentation red or white wine. With a rich touchscreen display and long re-chargeable battery life, the Sentia™ system makes it easy for you to get test results in under a minute, wherever and whenever you need.

And there’s more to come. Our team is working on more key wine analysis tests, so free SO₂ and Malic Acid is just the beginning.

Take Sentia™
everywhere you go

Sentia™ is light and portable. We’ve made sure it works just as well in your office as it does beside the barrel. With a footprint like your smartphone and battery life you can rely on, it is easy to carry wherever you need it.

Results in less than a minute

Small sample drop delivered to the Sentia™ free SO₂ Test Strip will deliver a result in under a minute.

No calibration. No reagents*

Avoid messy, time-consuming calibration or reagent preparation*. Everything you need is packaged into the Sentia™ Test Strips and Analyzer so you can focus on the results that matter to you.

*The Sentia™ Analyzer will need to be connected to Wi-Fi briefly, every three months in order to automatically acquire the latest calibration data for our Sentia™ free SO₂ Test Strip batches, although we recommend you connect whenever convenient.

Save on costs

Sentia is designed for use in the winery – at the barrel, tank or bottling line – so you won’t need to send samples off to the lab. Save on testing costs, logistics and time and take back control of your winemaking process.

“The Sentia free SO2 measurement tool has been a boon to a small winery like us who does not have a full lab. We can get immediate results at lower costs than outside labs—it was a no-brainer purchase that is going to improve our wine quality by allowing for more frequent testing and thus better SO2 protection of my wines.”

“The Sentia is fast, simple and above all convenient. It has been great to have a handheld tool that our staff can manage as easily as a pH meter. With the addition of malic acid testing, it will be worth every penny.”

“The Sentia free sulphur test and malic acid test has been a great addition to my winemaking tool kit.

“In the past I used a titrator for SO2 measurements, but it was tedious and time consuming, so when I saw the Sentia unit I was super excited! Now it’s easy, it takes less than a minute to measure a sample, AND I have a record of it in the unit without additional work. The addition of acids and sugars tests will multiply the Sentia’s usefulness. Best wine lab purchase ever!”

“The ability to run both free SO₂ and malic acid on the same device in a matter of seconds, and tracking the wine through Elevage makes Sentia an attractive tool in our winery. Coupled with its ease of use and on demand and just in time results it makes timely additions, avoiding issues down the road, easier than its ever been for us. The Sentia device frees up time and delays from waiting on shipped sample results to come in. Considering the origin of the technology in the healthcare industry we can see why the results are so precise and quick. It’s becoming an invaluable winery assistant for me.”

“Sentia is easy to use and provides quick, accurate results. But what’s exciting is the potential for future testing. For all the tests this unit will do makes it a smart, affordable choice for any size winery. Takes up very little space in the lab and handheld for portable testing in the cellar.”

“Sentia has fundamentally changed the way I work in the winery. I can check free SO2 almost instantly, on a tiny sample, with no concern about calibration or my consistency with test equipment. With the addition of tests for malic acid, glucose and fructose at the end of the year, I would consider it unusual for a winery not to be using Sentia.”

“Sentia is a great innovation. It’s really important to have an analysis tool that is compact so the portability feature is great. Compared to A/O, it is such a time saver – we can do a round of free sulfur testing in the winery in just over an hour so it frees up time to focus on other quality measures. You don’t need to be trained to use it so we can give the task to anyone in the winery and we know the result will be the same. When the sugars and malic tests become available Sentia will be irreplaceable.”

“The Sentia device has been a game-changer for me. Checking Free SO2 levels is an integral part of the winemaking process on a year-round basis, and this device puts the power of convenience and immediacy in my hands. I can check in on individual barrels or tanks or do composite checks any time that I’d like at a fraction of the cost of having a third party lab run the same analysis. I highly recommend this device to small and medium size wineries that value maintaining quality in their wines.”
