Experimental realization of cold 85Rb atom interferometers and their applications in precision measurements are reported in this paper. Mach-Zehnder and Ramsey-Bordè type interferometers were demonstrated. Detailed descriptions of the interferometers are given including manipulation of cold atoms, Rabi oscillation, stimulated Raman transitions, and optical pumping. As an example of using atom interferometers in precision measurements, the quadratic Zeeman shift of hyperfine sublevels of 85Rb was determined.
