Processors often have questions when it comes to measuring temperature in their facilities. This article aims to answer several of the most frequently asked questions heard by our engineers. Q: Why can't I use any multimeter for measuring temperature with thermocouples? What errors will result if I do not use a thermocouple temperature meter? A: The magnitude of the thermoelectric voltage depends on the closed (sensing) end as well as the open (measuring) end of the particular thermocouple alloy leads. Temperature sensing instruments that use thermocouples take into account the temperature of the measuring end to determine the temperature at the sensing end.
