Our thermistors are composed of a semiconductor material that changes resistance with temperature and is molded inside a rugged PVC housing or encapsulated in a stainless steel cylinder. They are available as either a single point probe (single thermistor) or as a string of multiple thermistors connected along a cable. All our thermistors are custom manufactured according to customer requirements for overall cable lengths, number of sensors, sensor spacing and accuracy making them ideal for monitoring temperatures profiles.
