Description of Product
The Length Comparator is designed for accurate measurement of dimensional changes in cement and concrete specimens during laboratory testing. It is widely used to evaluate length variation in accelerated soundness tests and to monitor shrinkage or expansion of standard 40 × 40 × 160 mm prisms as well as specimens of other sizes.
Built with a rigid steel frame and available with either an analog or digital dial gauge, the instrument provides precise and repeatable measurements. The adjustable upper anvil accommodates different specimen dimensions, making it a reliable solution for cement, concrete, and construction materials testing laboratories.
