The CALin provides its user with the ability to perform both vertical and horizontal linearity tests to verify the performance of an ultrasonic (UT) instrument. UT instrument verification is typically required by code (such as ASME Section V) to be conducted on a periodic basis. Due to its small size and minimal time to operate, it is envisioned that owners will use the CALin more frequently to confirm instrument performance as well as to use it as a system troubleshooting tool.
Other benefits of the CALin include providing a better test of instrument linearity as it removes operator variability which normally exists between a calibration block and a manually applied transducer. It is traceable to NIST via its factory calibration. It is compatible with a range of UT instruments regardless of original manufacturer. Lastly, the CALin is being offered at a special price to promote its introduction for orders received by December 31, 1998.
