METER TEROS 10 Soil Moisture Sensing
Preparation
Inspect and verify TEROS 10 components. The TEROS verification clip gives the
best assessment of proper sensor function and accuracy.
The TEROS 10 should read 0.35 to 0.42 m3/m3 on the verification clip. If a
verification clip is not available, test basic sensor functionality in air and
water. The TEROS 10 will read ~0.64 m3/m3 in water and a slightly negative
value in air.
NOTE: The sensors are optimzed to read in soils, therefore the sensor
will not read 100% in pure liquid water. Values above use the mineral soil
calibration.
Installation Tool
Proper installation of the sensors is critical for proper operation. Refer to
the TEROS 10 User Manual for details.
For easy installation, use the borehole installation tool. The installation
tool (shown below) is available for rent from METER Group. Contact Customer
Support for more information.
What is soil moisture?
Soil moisture is a key variable in controlling the exchange of water and heat
energy between the land surface and the atmosphere through evaporation and
plant transpiration.

ATTENTION
For best results, use the latest versions of METER software and firmware
for the computer or mobile device, products, and sensors.
Please use the software Help menu to find updates. Consult the sensor user
manual for more troubleshooting tips.
Installation
Insert Sensor
Auger or trench a hole to the desired sensor depth. Insert the sensor into the
undisturbed soil.
When using the borehole installation tool, load the TEROS 10 as shown. Lower
the tool into the hole or trench with the back of the tool supported by the
far wall. Pull on the lever to activate the jack and insert the sensor into
hole wall.
Check Sensor Operation
Plug the sensor into the data logger and use the SCAN function in the software
to do a quick check of sensor operation before backfilling.
Repack Soil and Protect Cables
Secure and protect cables with PVC casing or flexible conduit and backfill the
trench or hole.
Plug Sensor In and Configure Logger
Plug the sensor into the data logger. Use data logger software to apply
appropriate settings to the sensors plugged into each data logger port.
The TEROS 10 is an analog sensor and will not be automatically recognized on
METER data loggers. Select the right sensor for each port.
