i SAFETY ANALYSIS
SUMMARY
No formal safety evaluation of the gauge was performed by NRC.
The device was evaluated when Harrel, Inc. was issued their general distribution license.
However, a registration certificate for the device was issued by NRC on February 10, 1983, based on information submitted in Harrel's general distribution license application.
The Model TG-602 was an earlier design of the Model TG-601 manufactured by Harrel, Inc.
The Model TG-601 superseded the Model TG-602 and, as of the date of this document, the Model TG-601 is still being actively manufactured and distributed by Harrel, Inc. to general licensees.
According to Harrel, Inc., Model TG-602 gauges exist in the field and Harrel,.Inc. is chill providing leak testing and maintenance for these gauges.
