Thanks to a metal heat treatment company for choosing Sinowon ultrasonic hardness tester SU-400

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.
