When the QMT107 sensor is extracted, clean the dirt accumulation on
the sensor surface with a soft cloth or sponge using water and mild
detergent. Field repairs are accomplished by replacing the complete
sensor.
Soil Moisture Sensor
Periodic Maintenance
The ML2x sensor is sealed after the factory calibration. It does not
require any routine maintenance and it is constructed of materials
selected for robust field operation. If the measurement rods become
bent in use, they can be carefully unscrewed from the body and
straightened. They have a right-handed thread. Pay careful attention to
the following points:
- Do not remove the cross-head sealing screws. This may damage
the seal and will void the warranty. No internal maintenance or
repair shall be performed by the user.
- Do not remove the sensor from soil by pulling on the cable.
- Do not attempt to straighten the measurement rods while they are
still attached to the probe body. This may break the rods or damage
the case seal.
