1. Introducing Sentia™
How Sentia™ works
The Sentia™ system analyzes a sample applied to a Sentia™ test
strip
*
. The sample is applied after the test strip has been inserted
into the Sentia™ analyzer's strip port. The sample mixes with dried
reagents inside the strip and the analyzer detects the free sulfur
dioxide levels. The result is then displayed on the analyzer screen in
units of either parts per million or mg/L (user selectable).
Up to one thousand records can be stored in the analyzer’s memory.
You can list the records and download them to an external device for
external review and analysis.
Quality control
The Sentia™ analyzer has a number of integrated quality-control
functions:
 A check of components and functions is performed every time
the analyzer is turned on.
 During the test, the strip’s integrity is monitored. The strip’s
temperature is also controlled to ensure test results are
reproducible.
An error is reported if the analyzer fails any of the above checks.
Warning and error messages are described in Section 7
(Troubleshooting) on page 30.
