A temperature sensor with the features of "ultra-compact," "high-speed response," and "non-contact." It is ideal for medical, healthcare, and wearable devices.
<Thermometer> ●ET-3H Achieves a more compact design than conventional products! It features very small temperature measurement errors due to the high-precision classification of thermistor characteristics. ●FT-ZM A unique product from SEMITEC! Created through the thin-film technology of thermistors that is not found in other companies! The characteristics of the thin-film thermistor "FT series," being "thin" and "compact," allow for surface contact with the measurement part, achieving a 70% increase in response speed compared to the conventional "ET-3H." <Catheters> ●Fμ Sensor Offering ultra-small sensors with diameters of 0.5 mm and 0.3 mm! This is a small and high-precision thermistor sensor created through thin-film technology and microfabrication technology. The development of the thin-film thermistor Fμ series not only allows for miniaturization but also incorporates trimming technology to ensure uniform thermistor characteristics, achieving high precision (characteristic tolerance ±0.3%). This product has a proven track record in medical (catheter) applications. <Ear Thermometer> ●Thermopile It can detect infrared radiation emitted from the eardrum, allowing for non-contact body temperature measurement! It is used in "ear thermometers" and also in forehead thermometers commonly seen during the COVID-19 pandemic.
