Airman 1st Class India Brooks, 57th Maintenance Squadron Precision Measurement Equipment Laboratory specialist, delivers a scale in need of calibration to the PMEL Oct. 28, 2013, at Nellis Air Force Base, Nev. Airmen assigned to PMEL are technicians responsible for the repair, calibration and modifications of all measurement equipment in the Air Force. According to the Air Force website, PMEL specialists are trained to calibrate more than 7,000 different pieces of equipment ranging from torque wrenches to aircraft scales.

Tech. Sgt. Jeff Tucker, 57th Maintenance Squadron Precision Measurement Equipment Laboratory section supervisor, places a measurement scale awaiting calibration in the holding area Oct. 28, 2013, at the PMEL on Nellis Air Force Base, Nev. Each piece of equipment is placed in the holding area for a minimum of four hours so it can adjust to the temperature of the laboratory before being calibrated. Some equipment that PMEL aligns, calibrate differently in hot or cool climates. (U.S. Air Force photo by Staff Sgt. Michael Charles)
