Thermometer for underground
【Model number：JK5H-42】
Model：JK5H-42
This device sticks a spear into deep sea-bed and is a device measuring the underground temperature at under seabed.
It is located few thermistors in the spear and can measure underground temperature at the same time for longitudinal some points.
In addition, It is possible to measure a thermal diffusion of the underground by heating the heater line in the spear.
The withstand pressure container of the main body assumes it the slim shape that it is easy to treat in a robot hand in consideration of the use with midget submarines such as ROV, and magnet SW to do it has a heater in on forcibly.
t enable the long-term observation in the sea and also observation in the strong corrosion area by using titanium in materials.
