Hi there,
I don’t think Seeed is the manufacture of this device and Doubt they have anything additional on it.
What is the issue you have with it?
I believe it’s potted inside and a picture wouldn’t show anything?
You see the listed feature?
● Soil moisture content, electrical conductivity and temperature all in one
● One solution can also be used for fertilizer, and other nutrient solution conductivity matrix
● Electrode using special treatment of the alloy material, can withstand a strong external impact, not
easy to damage
● Completely sealed, acid and alkali corrosion, can be buried in the soil or directly into the water for
long-term dynamic testing
● High precision, fast response, good compatibility, the probe insert design to ensure accurate
measurement, reliable performance
● Perfect protection circuit
