P3782 and P4736 series have a thermal compensation detector element to minimize noise fluctuations caused by ambient temperature
variations. P3782 and P4736 series are well suited for portable analytical instruments.
Features
l Omnidirectional detection
l Custom detectors available
(including window materials not listed in our catalog)
l Fewer adverse effects from abrupt temperature changes
Applications
l Radiation thermometers
l Flame detectors
l Gas analyzers

*1: Measured with 500 K light source (black body) and 1 Hz chopping frequency.
*2: Calculated with portion of input energy from 500 K light source limited to the spectral response range (Sensitivity of other
types is calculated with the entire radiant energy at 500 K.)
*3: Measured under same conditions as *1 and 1 Hz amplifier bandwidth.
