The surfaces roughness tester is a small handheld instrument, for shop floor use and mobile measure, it operation simple, function overall, measure fast, accuracy stability, take convenience. This tester applies to production site and can be used to measure surface roughness of various machinery-processed parts. This tester is capable of evaluating surface textures with a variety of parameters according to various international standard. The measurement results are displayed digital/graphically on the color graphic LCD display, And output to the printer.
NG-SR200-T and NG-SR300-T System
Surface roughness testers offers a linear roughness measurement. This is done by tracing a mechanical tip along a surface to measure roughness along an arbitrary line. As the equipment evolves in sophistication, manual contact methods may be replaced by last, optic and other testing processes for faster and more user-friendly results. Contact our quality consultants today to help identify which surface roughness testing system would be the optimal solution for your testing needs.
The surface roughness values are normally displayed in Ra, which is the average absolute deviation from a central line of a surface. Additional values include the Rq, which is the root mean square of the deviation. There is a vast number of other testing scales depending on your specific requirements. A more advanced surface roughness tester may offer more testing scale options.
After the test, the data collection system is processed with digital filtering and parameter calculation system via a DSP chip and the measuring result can be read on LCD screen or simply printed through printer and communicated with PC.

LeebGen3000 is a non-destructive precision metal hardness tester developed according to the latest industry standards. LeebGen 3000 is equipped with features which provide the instrument with a combination of a user-friendly interface and exceptional test result accuracy. This in turn allows for ease of operation and an accurate conversion display of virtually any metal hardness testing value.
Welcome to our most advanced and cost-effective Ultrasonic Hardness Testing System. This portable machine is all you need and more!
Telebrineller - Measuring Brinell Hardness anywhere in the field, the plant or the laboratory. A test bar of known BHN (Brinell Hardness Number), approximating the hardness of the specimen to be tested, is selected. Consistent accuracy is maintained when the test bar BHN is within + or -15% of the specimen BHN and is of the same general material.
Certified Test Blocks are a requirement as a reference material for any type of hardness testing. At NextGen, we understand the importance of a Test Block to ensure the accuracy of your hardness testing procedures.
