Metrix Plus 1.5 V Digital Rubber Hardness Tester has an indenter present in it, loaded by a calibrated spring that measures the intender's penetration depth under the load. Digital Rubber Hardness Tester is ideal for measuring the degree of softness and hardness such as Neoprene, Nitrile Rubbers, cast resins etc. It has a testing pin beneath the digital LCD, which penetrates the rubber material to measure its hardness and flexibility. The more significant number on the 1.5 V Digital Rubber Hardness Tester LCD Display indicates the rubber material's high rigidity, and the low number indicates the rubber's softness. The device is provided with an average value calculation function for easy statistical analysis.
