In developing the Sentia™ free SO₂ system, Universal Biosensors created the Sentia™ free SO₂ Test Strip using their heritage in electrochemical technology developed in the medical device field. They then matched this to the hand-held Sentia™ Analyzer boasting a color touchscreen display and wireless connectivity.

Their goal was simple: take the pain out of free SO₂ testing. Make your own testing simpler and faster. No more sending samples to the lab waiting days for the data to come back or messing with reagents and titrations. Just reliable test results you can collect yourself in under a minute.

  4. Remove a strip from the vial then securely close the vial. Always store strips in the fridge when not in use.
  5. When prompted, insert the strip gently but firmly into the Analyzer
  6. Only when prompted, apply the sample on to the end of the strip.
  7. When the analysis is complete, the test result will be presented.

**Updating your Sentia™ Analyzer: The Sentia™ analyzer will need to be connected to WIFI briefly every three months in order to automatically acquire the latest calibration data for the Sentia™ Free SO2 test strip batches, although we recommend you connect whenever convenient.

How It Works

The Sentia™ system measures free SO2 directly by a modern, miniaturized version of the  technique of voltammetry. There is no need to add reagents; the system is pre-calibrated to work directly on the sample when applied to the strip.
