U.S. Air Force Staff Sgt. Kurt Hatch, 92nd Logistics Readiness Squadron assistant noncommissioned officer in charge, evaluates the results of transmission fluid analyzed by the Micro Lab 40 Series at Fairchild Air Force Base, Washington, Nov. 4, 2019. The oil analysis takes about five minutes per sample and provides data that technicians use to see if the oil needs to be changed or if there are indicators of future damage or component failure.
