Gauss meter field strength meter and the difference in our everyday gauss meter and Changjiang Yi often confuse our object has been to them as a class of products, it is used to detect the magnetic field, not just customers, we sell who will also confusing to introduce it at different points between the two products have? 1 is not the same as the detection of Gauss magnetic field intensity meter is detected, the DC / AC motor test, measurement and classification magnet, the magnetic field distribution of the test, the speaker quality control, tool remanence measurement, laboratory applications, non-destructive testing applications, power plant / substation interference magnetic field measurement. Signal Level Meter TV signal strength is detected, the main level, electrical, radio frequency and other television detection. 2 units of different units of gauss meter mT, Gs, Oe, kA / m. Strength Meter unit is dBμV and Hz I choose what kind of hardness of it, this has become our common problem, the foundry industry is our longest hardness see a device that I was in a number of cases Choose what kind of hardness, it is in the hardness, Rockwell or Brinell hardness tester? This is a problem, come I'll take you into the hardness of the hall, so we can better understand the hardness, you know choose Leeb hardness tester, Brinell hardness, Rockwell hardness and under what circumstances. Hardness often divided in the hardness, Rockwell hardness, Knoop hardness, Brinell hardness, Shore hardness, Shore hardness, Barcol hardness, Mohs hardness, Vickers hardness tester, Webster hardness tester, micro hardness tester. Because of different durometer hardness measurement principle is different, so the scope is different. In the selection of the hardness of the timing must be based on actual needs and to achieve results to select the application. The following describes the different types of hardness characteristics and differences. 1, Rockwell hardness for ferrous metals, nonferrous metals and nonmetallic materials hardness testing. Rockwell hardness indentation is small, there are localized measurements shall be measured by averaging the number of points for finished products and sheets. 2, Knoop hardness (HK) suitable for hardness testing of high hardness of the material (usually more than HV1000 hardness hardness measurements). 3, Brinell hardness tester for measuring annealing, normalizing, quenching and tempering of steel, cast iron and non-ferrous metal hardness, indentation hardness due to the large cloth, not the non-destructive testing, and therefore does not apply finished and flakes. 4, Shore hardness widely used in rubber, plastic hardness measurement. 5, Brinell hardness tester for measuring annealing, normalizing, quenching and tempering of steel, cast iron and non-ferrous metal hardness, indentation hardness due to the large cloth, not the non-destructive testing, and therefore does not apply finished and flakes. 6, Barcol as a special measure fiberglass products, enhance or increase specific detection tool hard plastic, aluminum and aluminum alloys, brass, copper and other soft metal hardness. 7, Vickers hardness tester is more suitable for measuring small, thin specimen surface after the coating treatment of bleeding parts, such as nonferrous metals, IC thin, thin plastic, foil, coating, surface coating, laminated metal, heat treatment of carbonization layer and hardened layer hardness measurement. 8, Webster Hardness (HW) applies to aluminum products Vickers hardness measurements. 9, micro-hardness material determination of small, micro-hardness thin specimen, surface coatings and other specimens infiltration and determination of glass, ceramic, agate, precious stones and other man-made hard but brittle.
