Model: HNJ-NES
Test method: eddy current
Standards: GB/T 50082-2009
Test index: displacement, temperature, humidity
This equipment is used to measure the free shrinkage deformation of concrete at any time after self-forming, and also can be used for the determination of self-shrinkage deformation of early-age concrete under no external wet exchange conditions. The instrument is manufactured in accordance with the GB/T 50082-2009 [Standard Test Method for Long-Term Performance and Durability of Common Concrete], uses eddy current method.
