The mechanical durometer is designed for measuring the surface hardness (Shore A) of materials such as very soft rubbers and elastomers, as well as soft plastics. The instrument is made from a single robust block with an integrated measuring head and a 360º anti-reflective dial, which allows for a clear and precise reading of results. It can be calibrated at any time to maintain accuracy. The drag pointer, a distinctive feature, enables precise peak value reading by remaining fixed at the maximum value reached during the test. After reading, the pointer can be easily reset to zero for a new measurement cycle, enhancing operational efficiency in repetitive testing contexts.
