Kyowa GTI-E201-1MPS GTI-E201-S Plate type soil pressure gauge
Made in Japan
Manufacturer: Kyowa Electronic Instruments Co., Ltd.
Model: GTI-E201-1MPS
Measures subsoil pressure without disturbing the ground at the installation site.When installing the soil pressure meter, measurements can be made by simply drilling and inserting a bore hole at the soil pressure measurement point, without extensive excavation, shaping, or backfilling of the installation site. Earth pressure can be measured without disturbing the condition of the soil pressure measurement location.
Features
No need for extensive open excavation and backfilling during installation

For correct use
●This device is made of a thin metal plate, so do not hit it with sharp objects or corners.
●The instrument can be inserted using a gas pipe, etc., but a jig is also available.
●When using by inserting, please use it on the ground with N value of 5 or less.
remarks
The mainland pressure gauge is a jointly developed product with the Regional Geoenvironmental Research Institute.
