QualityWorX data management and analytics for the CTS Sentinel C28

CTS and Sciemetric have now made it possible to collect, store and analyze data from a selection of CTS instruments using QualityWorX.

Turnkey Package to Get Started

Customers can now connect several CTS Sentinel C28 instruments at a time using the QualityWorX CTS DataHub, a quick and easy turnkey platform for collecting and analyzing data, without requiring complex IT support or set up.

Scalable Database Options for Broader Data Collection

Want to collect data from more CTS instruments or to aggregate leak test information with data from  other tests? Scale up to a QualityWorX database solution to cover as many stations as you need. Learn more about QualityWorX.


Current QualityWorX customers can now add CTS Sentinel C28 data to their database!

Contact your sales representative to talk about connecting Sentinel C28 instruments to your QualityWorX database.
