Portable Hardness Tester Warranty

Product description: SU-400 Super Hardness Tester is a  multifunctional  portable hardness tester combining dynamic rebound Richter scale measurement method and static ultrasonic dimension measurement method. SU-400 can not only support ultrasonic manual HP-1K, HP-2K, HP-5K, HP-10K probes and electric MP-300, MP-500, MP-800 and MP-1000. SU-400 has two functions. It can be used to measure thin and rough samples by ultrasonic method, and it can also be used to measure rough samples by Richter method. On one machine, not only the problem that Richter hardness tester can't measure the samples of electroplating layer and hardness layer is made up by ultrasonic method, but also the problem that ultrasonic wave can't measure the hardness of coarse-grained materials is made up by Richter method.Use of ultrasonic hardness tester:1. No damage to the surface of the workpiece to be tested, simple operation, good stability and high testing accuracy;2. The matching test bracket has the advantages of fast batch detection speed, simple operation and high test accuracy for finished small workpieces;3. It can detect metal flakes, small pieces of metal thin layers (including nitrided layer, carburized layer and electroplated layer), special-shaped pieces, immovable large workpieces, etc.4. Conversion of cloth, Brinell，Rockwell，Vickers; The measured workpiece with uneven hardness distribution can be averaged by multi-point accumulation;5. Hand-held probe can be used to directly detect the workpiece.6. The difference between ultrasonic hardness tester and desktop hardness tester: after the Brinell and Rockwell tests, the indentation is obvious, and the sample needs to be reprocessed or scrapped, which is suitable for sampling inspection. The indentation of ultrasonic hardness tester cannot be directly observed by naked eyes and is suitable for full inspection. The test time of table hardness tester: Rockwell 25 seconds, Vickers 50 seconds, Brinell 60 seconds, and ultrasonic hardness tester 2 seconds at the earliest. Vickers hardness tester has high requirements for operators, and ultrasonic hardness tester is simple to operate with one key. The desktop instrument is heavy and suitable for laboratory, and the ultrasonic hardness tester is portable and suitable for field testing.

Ⅰ.Product Introduction: Sinowon Roller Ultrasonic Hardness Tester SU-320R is a customized ultrasonic hardness tester specially developed by Sinowon for the plate making industry. SU-320R solves the problem that other portable hardness testers such as Leeb hardness testers cannot accurately detect the hardness of the copper and chrome plating layers of the plate roller. At the same time, due to the use of ultra-low force probe MP-200, it can accurately detect the hardness of the plate roller without leaving obvious test indentations on the plate roller.Ⅱ. Under what circumstances is it better to use an ultrasonic hardness tester?1.Full inspection or large-scale sampling is required. The single measurement cycle of the ultrasonic hardness tester only takes 2 seconds, which is 15 times the measurement efficiency of the traditional desktop hardness tester and 50 times that of the Brinell and Vickers, which can greatly improve the measurement speed and efficiency.2. The sample is relatively large and is not suitable for direct detection by a desktop hardness tester: Because the ultrasonic hardness tester is a portable hardness tester, it can solve the problem of on-site measurement of the hardness of large workpieces.3. Do not want the tested sample to leave obvious test indentations:Since the test force of Brinell and Rockwell hardness testers is relatively large, a large indentation will be left after the test. After the test, the product cannot be assembled and used or needs to be processed again, and the customer requires the manufacturer to perform hardness testing. The ultrasonic hardness tester uses a small load test force and uses a diamond Vickers indenter. The test indentation requires a microscope of 200X or more to be clearly distinguished. The indentation is not easy to be observed by the naked eye, thus solving the above problems.4.It is necessary to measure the hardness of the surface coating of large products: Since traditional portable hardness testers such as Leeb hardness testers cannot measure the hardness of the surface coating of most products, and ultrasonic hardness testers use a small load test force, after calibration, the surface coating can be measured for hardness without damaging the finished product, thereby adjusting and controlling the production process of large products and effectively ensuring the production quality of the products.

With the rapid development of the automotive industry, the material performance requirements for automotive parts are becoming increasingly stringent. As an advanced material testing equipment, the innovative application of Sinowon Micro Hardness Tester in the automotive industry not only improves the accuracy and efficiency of material testing, but also greatly promotes the quality control and R&D innovation of automotive products. Hardness testing is crucial in the automotive industry to ensure that aluminum parts meet the required standards, prevent tool damage and extend the service life of parts.1.What is a Micro Hardness tester:Micro Hardness testers have been widely used in the development, research, actual testing and quality management of metal materials.Hardness in special fields, especially Vickers hardness and Knoop Hardness as substitute properties to replace other material properties.It is often used to measure the hardness of each phase in the material or an extremely thin layer on the metal surface (such as electroplating layer, nitriding layer), etc. Its value can be expressed by Mohs hardness HM, Vickers hardness HV or Knoop hardness HK. During the measurement, the sample must be ground and polished to a bright surface, and then exposed to the micro structure after erosion, and then tested and observed under the Micro Hardness tester.2.Working conditions: The Micro Hardness tester should work within the temperature range of 20℃±8℃, and the humidity should be kept within the range of ≤70%. It is strictly forbidden to use it in an environment with dripping water or dust, let alone in an environment with corrosive gas and radiation. The Micro Hardness tester should be fixed in a fixed position and is not suitable for frequent handling or carrying.3.Sinowon Micro Hardness tester device composition: The Micro Hardness tester consists of a host, a micrometer eyepiece, various test benches, a standard hardness block, various indenters, an objective lens, a leveling angle, etc.The micrometer eyepiece is used to observe the metallographic or micro structure, determine the test site, measure the diagonal length, collect data, etc.; the hardness tester host completes the switching between the eyepiece and the indenter, applies the load at the determined test site, completes the movement of the platform to find the image point, etc.; the related accessories are mainly for the clamping and stabilization of the specimen, etc.4.Main uses of Micro Hardness tester: Micro Hardness tester is mainly used to measure tiny, thin specimens and brittle hardware. By selecting various accessories or upgrading various structures, it can be widely used for various metals (ferrous metals, non-ferrous metals, castings, alloy materials, etc.), metal structures, metal surface processing layers, electroplating layers, hardened layers (oxidation, various infiltration layers, coating layers), heat treatment specimens, carburized specimens, quenched specimens, tiny parts of phase inclusions, glass, agate, artificial gems, ceramics and other brittle and hard non-metallic materials. Multi-point measurement with precise positioning in fine parts, deep testing and analysis of indentations, testing and analysis of infiltration layers, testing of hardness gradients, observation and research of metallographic structure, measurement and analysis of coating thickness, etc. It is an essential testing instrument for laboratory quality inspection departments, quality control of metrology institutes, and material research.5.Working principle: The Micro Hardness test is to press a diamond tetrahedral pyramid indenter with an angle of 136° between two opposite faces into the sample surface under a certain test force. After maintaining the pressure for a certain period of time, the test force is removed, the diagonal length of the indentation is measured, and then the corresponding table of diagonal length and Micro Hardness value is checked to obtain the Micro Hardness test value.
