Precision means accuracy. A precision instrument is a top quality one that is super-accurate. You can get an instrument that will just do the job, or you can spend extra money and get a precision instrument that will be perfect. Many measuring devices are precision instruments because they must be totally accurate.
A precise instrument. It is not necessarily accurate.

No. Accurate relates to how close the actual measurement the instrument measures. Precise relates to how much detail the instrument gives when measuring. They are independent to each other: An measurement can be precise and accurate (eg the value of π is 3.141592654) An measurement can be precise and inaccurate (eg the value of π is 1.733677432) An measurement can be less precise and accurate (eg the value of π is 3.14) An measurement can be less precise and inaccurate (eg the value of π is 1.73).
Interferometry is a measuring instrument that uses an interference pattern to make accurate measurement of waves. This instrument uses optical, acoustic, and radio frequencies.

A very accurate mass spectrometer is needed.
Yes, but then there is no point in using an instrument that is that accurate!
