Additionally, as an option, the instrument may be used to determine the compressive strength of the cement using the same algorithms and method found in a conventional Ultrasonic Cement Analyzer (UCA). This testing methodology was included in API10B6 original version but was later removed as it’s patent protected and exclusive to Chandler Ametek. The machine is known as Static Gel Strength Analyzer (SGSA).http://www.skyray-instruments.....net/construction-mat
