1. A method performed in a coating testing system for automatically determining the polymerisation of coating material, the method comprising:
positioning a near infrared spectroscopy, NIR, spectrometer probe adjacent to a wire to acquire NIR spectra, the wire comprising a polymer coating, wherein the spectrometer probe is maintained at a fixed distance from the wire, such that the spectrometer probe does not contact the wire, and a fixed orientation relative to the wire;
acquiring NIR spectra of the polymer coating using the probe; and
performing chemometric analysis on the acquired NIR spectra in order to measure the polymerisation of the polymer coating,
wherein the probe is a reflection probe.
