In our warehouse and lab here in Gonzales, Texas, with a staff of five, we are processing, evaluating, testing, grading and, as necessary, repairing these meters and dosimeters. We also perform extensive preventative maintenance to assure reliable service in the field. Every step in this process is to prepare these meters and dosimeters for eventual successful certified calibration by a top-rated lab specializing in, and equipped for, calibrating these same type Civil Defense radiological instruments.
