Patent ID: 11137352

Abstract:
The invention relates to a portable device for estimating at least one parameter characteristic of a polymer material, characterized in that the device comprises at least one infrared source, each infrared source being capable of emitting towards the polymer material a spectral line, representing maximum emission energy, selected in one of the wavelengths 10 μm, 9.5 μm, 7.2 μm, 6 μm, 3.5 μm, 2.7 μm or in one of the wave numbers 1,000 cm−1, 1,050 cm−1, 1,350 cm−1, 1,700 cm−1, 2,900 cm−1, 3,700 cm−1, at least one infrared detector, capable of receiving infrared radiation, which is reflected by the polymer material in response to the spectral line, a unit for determining the parameter characteristic of the polymer material as a function of the energy present in said spectral line in the infrared radiation, having been reflected by the polymer material and having been received by the infrared detector.
