KM Series
Embedded Strain Gages
Summary
The KM series gages are designed to be embedded in mortar or concrete for the purpose of measuring the internal stress.
To ensure better adhesion to mortar or the like, the KM series gages feature a specially treated surface.
They also provide suitable waterproofness and elastic modulus for the intended purpose.
