The high-precision Penning-trap mass spectrometer PENTATRAP is currently being commissioned at the Max-Planck-Institut für Kernphysik, Heidelberg. PENTATRAP aims at mass-ratio measurements of single stable and long lived highly charged ions with a relative uncertainty of a few 10⁻¹² through measurements of their respective cyclotron frequencies in the strong magnetic field of a Penning trap. At this precision level, PENTATRAP will, for instance, contribute to electron-neutrino mass related measurements within the ECHo collaboration, which investigates the de-excitation spectrum following the electron capture in ¹⁶³Ho.

The main features including the detection system, the traps and the ion creation part will be presented in the poster.
