PRODUCT
The 105E consists of a shielded, 24-AWG, type E
thermocouple wire. Its junction is electrically isolated from
the soil (or other media being measured). Electrical isolation
avoids measurement errors due to differences in ground
potential.
Type E thermocouples are comprised of a chromel wire and
a constantan wire joined at a measurement junction. A
voltage potential is generated when the measurement end
of the thermocouple is at a different temperature than the

Overview
The 105E is a thermocouple designed to measure soil temperature. It easily interfaces with our dataloggers.
Benefits and Features
Junction is electrically isolated from the soil, thereby avoiding measurement errors due to differences in ground potential
Compatible with most Campbell Scientific data loggers
Technical Description
reference end of the thermocouple. The magnitude of the
voltage potential is related to the temperature difference.
Therefore, temperature can be determined by measuring
the differences in potential created at the junction of the
two wires.
A reference temperature measurement is required for
thermocouple measurements. The temperature sensor built
into many of our dataloggers' wiring panel typically provides
this measurement.
