The CellaTemp® PX 15 has a narrow-band filter with a spectral sensitivity from 4.6 to 4.9 microns. Thus, it detects the temperature of the near-surface region of the glass. Thickness variations or different types of glass has no influence thanks to the wavelength. Also, there is perturbation due to atmospheric influences such as changes in humidity.
