DIK-D300 Cone Type Multi Soil Moisture SensorNEW!
Main Characteristic
Cone type Multi Soil Moisture Sensor is the first sensor in Japan (According to our research) that is possible to select the measurement frequency to suite the soil, making it ideal for measuring soil with high moisture content. (Patent pending)
It can also measure temperature, EC (electrical conductivity), and tilt angle (selectable on or off) simultaneously. As it can measure moisture while inserting into the soil, it is possible to take moisture values in a soil profile.
We plan to sell a system that can measure soil moisture while measuring soil hardness by using it in conjuction with a digital cone penetrometer.

Q&A
Q: When I want to measure moisture, do I need to insert the entire sensor part (pin part) into the soil?
A: Yes, it is necessary to insert the entire sensor part into the soil. If it is inserted only halfway, the measured moisture value will tend to be lower than the actual value.
