Why should I send my TSI flow meter or flow analyzer to TSI? Can't I use a third-party service?

TSI performs certified, multi-step service with original factory parts for quality service and support you can trust. Only TSI can calibrate your flow device and provide legitimate, NIST-traceable calibration certificates.

Third-party service providers can only verify whether your instrument is measuring within specification – they cannot calibrate it. If a calibration is needed, the third party must send it to a TSI service center.

	TSI Factory	Third-Party
Service turnaround time	5-6 Days	Days to Weeks*
Leak check	YES	YES
As-Found calibration check	YES	YES
