KMC Series
Concrete-embedded Strain Gages
Summary
The KMC series gages are designed to measure self-shrinkage and self-stress of cemented materials.
They enable measurement of the self-shrinkage and high-fluidity concrete immediately after placing.
They are also used effectively to check for cracks of cemented materials.
Usually, a T-type thermocouple is installed near the gage, while the KMC series gages of H4 type do not require such the installation since they are equipped with a built-in thermocouple.
