Brief introduction: HY - 31 ultrasonic hardness tester, leading technology, easy to use, high precision, breaking the foreign products in the domestic product and price monopoly for many years. HY - 31 portable ultrasonic hardness tester is using the ultrasonic vibration principle to measure the hardness of a new type of intelligent instrument, it is mainly used for measuring metal rockwell hardness (HRC), bring their own transformation function, can be converted to the corresponding brinell (HB), vickers hardness (HV), according to the value with storage capabilities, is currently the portable hardness tester of the smallest dimple hardness tester. Y - 31 ultrasonic hardness tester can be adapted to any shape size of the workpiece, in machinery processing, steel, automotive, aerospace, petrochemical, electric power, heat treatment, mold, gear, supervision, inspection and scientific research and teaching in areas such as widely used Technical parameters: Measuring range: 20-70 HV HRC 70-100 - HB 100-540 Display precision: rockwell hardness display, display precision is 0.1 HRC Show value accuracy: + / - 1.0 HRC (HRC for 50-70, conform to and higher than the national standard JB/T9377-1999) HV/HB according to German standards for HV/HB + 5 (3%) Load: 10 nf + 1 nf Head specifications: 136 ° diamond indenter Instrument use power supply: AC 100-240 - v 50/60 hz DC 6 v provided by the built-in rechargeable battery Dimensions: 180 x 95 x 40 mm Weight: 700 g
