Temperature
The
Profile Probe
has a very low intrinsic sensitivity to changes
in temperature, as in this example:

This relationship is dependent on soil composition (particularly
clay content) and the soil moisture level, see ref. [7].
Electromagnetic Compatibility (EMC)
Europe
The
Profile Probe
has been assessed for compatibility under the
European Union EMC Directive 89/336/EEC and conforms to the
appropriate standards, provided the probe body and moisture
measuring rings are completely inserted into the access tube
within the soil or other material being measured. The cable
connecting the
Profile Probe
to its associated instrumentation
should be routed along the surface of the soil.
If the probe is not installed in this way, some interference may be
experienced on nearby radio equipment. Under most conditions,
moving the equipment further from
Profile Probe
(typically 1-2
metres) will stop the interference.
Profile Probes
installed near to each other will not malfunction
due to interference.
North America
