Accurately measure temperature through flames and combustion gases. The Advanced Energy Impac® IPE 140/39 pyrometers are specifically designed for non-contact temperature measurement of metal parts in flame-heated furnaces. It features a narrow spectral range of 3.9 µm that eliminates the influence of humidity and CO2. The IPE 140/39 can also measure glass temperature if limited glass penetration is necessary (e.g. glass drop). Utilize to avoid measurement errors caused by partially cooled down surfaces.
