If channel to channel isolation is poor, like most of Thermal Data Loggers or DAQs in the field, live electricity with high voltage potential would damage the Thermal Data Loggers/DAQs. Good electrical insulation is normally also good thermal insulation. Therefore, customers are capable of connecting a thermocouple to points of interest directly when using Chroma Thermal Data Loggers with highly reliable and accurate measurements. In addition, well-insulated channels also eliminate the need for extra insulation over the thermocouple.
