Our high-performance dual-wavelength sensors offer unequalled performance for accurate and repeatable measure-ments on kiln applications. These sensors can operate properly when the target energy signal is diluted over 99% by such things as dust and smoke. To effectively measure targets through flames, the 1400 and 4400 Series are recommended. These single-wavelength sensors utilize a very narrow band 3.8 micron filter that provides unequalled performance with measurements through flames.
