Can someone educate me with regards to "temperature compensated" thank you There are various types of temperature sensors. The kind called a "thermocouple" uses a very specific alloy of wire. Accurately measuring temperature with one of these sensors requires that the measurement circuit know the temperature at the point that this alloy is connected to copper. (This is misleadingly called the "cold-junction" temperature.) Cheap devices omit this cold-junction temp measurement and are less accurate as a result. |
