THERMOPILE detectors for THERMOMETRY ISOthermal, Miniature Thermopile Detectors For Ear Thermometry TPiD 1T 0122B, TPiD 1T 0222B, TPiD 1T 0622B Thermopile Detector Product Description As the optimum choice for Ear Thermometry, Excelitas offers thermopile detectors, referenced as ISOthermal detectors. The patented designs provide for superior thermopile performance under thermal shock conditions, and thereby are best suited for ear thermometry. The range consists of the TPiD 1T 0122B as our low-cost version, with the other versions providing higher signals, either because of high sensitivity element designs or larger element area. The physical dimensions of the ISOthermal sensors are equivalent to our TO-46 sensor housings and include a special aperture. All models are equipped with an internal Thermistor as a temperature reference for thermopile temperature compensation to further improve accuracy.
