Product description
The NELD-LS730 non-contact laser shrinkage and expansion tester uses imported high-precision laser displacement transducers to perform accurate measurement on the shrinkage and expansion of cement, mortar, concrete and any other materials. This instrument is capable of performing early age free systolic measurements transversely on double-channel specimen and longitudinal on cementitious materials like cement in single-channels.
Imported laser displacement transducer uses laser technology to obtain accurate non-contact measurements of the location and displacement of tested objects.
This product can equip 2 channels while enabling each channel to function independently or for dual-end measurement. This machine possesses multiple functions, state-of-the-art technology, and a wide range of adaptability. It is a highly-accurate one-of-the-kind product on the market that is capable of measuring the shrinkage and expansion of both cement and concrete.
