Profile: Quality Thermistor, Inc. specializes in providing thermistors. Our products include negative temperature co-efficient (NTC) temperature probes, miniature NTC sensors, surface mount thermistors, NTC thermistor elements, and positive temperature co-efficient (PTC) thermistor elements. Our miniature thermistors are ideal for measuring temperature in confined areas. The micro tube thermistor is an epoxy filled polyimide tube. The low thermal mass of the temperature sensor allows for a very fast thermal time response. Our thermistors are used in biomedical, air flow sensors, medical and instrumentation applications. Our negative temperature co-efficient thermistors exhibit a non-linear, decreasing electrical resistance with increasing environmental temperature. Our thermistors exhibit a non-linear increasing electrical resistance with decreasing environmental temperature. We are ISO 9001:2000 certified.
