N-type thermocouples are used in many applications where temperature measurement is required. They have been proven over time as reliable and accurate instruments for measuring temperatures. The N-type thermocouple has an internal resistance that varies directly with temperature. This characteristic makes it ideal for measuring low temperatures.Type N Thermocouple (Nicrosil / Nisil):  Type N shares the same accuracy and temperature limits as  Type K.  Type N are slightly more expensive.
