Kyowa KMC120Ωsingle axis KMC Concrete Embedded Wire Strain Gauge
Made in Japan
Manufacturer: Kyowa Electronic Instruments Co., Ltd.
This strain gauge is used to measure the self-shrinkage and self-stress of cementitious materials, and can measure the self-shrinkage of high-strength, high-fluidity concrete immediately after it is placed. It is effective for examining cracks in cement-based materials. Normally, a T thermocouple is attached near the gauge, but the H4 type has a built-in thermocouple.
