沈阳天星试验仪器有限公司是专业生产便携式硬度计的企业，我们生产的便携式洛氏硬度计、表面洛氏硬度计、韦氏硬度计、里氏硬度计、涡流测厚仪等产品广泛应用于金属热处理、淬火、金属加工等行业，用于测试不锈钢、钢管、冷轧薄钢板、钢带、镀锡板、镀锌板、铝型材、铜管、硬质合金、量具、刃具、刀具、冲压件等产品。

PHR系列洛氏/表面洛氏硬度计改变了传统的金属硬度测试概念，可以象千分尺一样使用，实现了硬度计的小型化、轻便化。仪器重量只有台式硬度计的百分之一，精度与台式硬度计相同。W-20系列韦氏硬度计主要用于测试铝型材的硬度，也可测试铜管、铜板带和经过热处理退火的不锈钢带、冷轧板、冷轧钢带的硬度。韦氏硬度计十分适于在生产现场使用，特别适于在不锈钢带、冷轧钢带、铜带的生产过程中对退火带材产品进行不停机的在线硬度检测，测试过程只需要1秒钟时间。

Tianxing Testing Instruments Co. Ltd.
Shenyang Tianxing Testing Instruments Co. Ltd. is a professional manufacturer of portable hardness testers. Our products include portable Rockwell hardness testers, portable superficial Rockwell hardness testers, Webster hardness testers, coating thickness gauges and some other products. Our products are widely used in the metal industry for heat-treatment, hardening and machining inspection.

Our products are capable of testing stainless steel sheets, cold-rolled steel sheets, steel strips, steel pipes, tinned steel sheets, galvanized sheet, aluminum alloys, brass, carbides, measuring tools, cutleries, cutting tools, stamped parts and other metal products.

PHR Series portable Rockwell hardness testers have brought a revolution to the traditional means of hardness testing. Weighing only one hundredth of a bench-top Rockwell tester, they can be easily used like a micrometer.

The portable Rockwell hardness testers have the same precision as the traditional bench-top testers, and are very easy and simple to use. Vertical testing force is no longer required, and it takes only 10 seconds to complete a single test.

W-20 Series Webster hardness testers are mainly used for testing aluminum profiles. They can also be used for testing the hardness of copper pipes, sheets and strips, and heat-treated stainless steel strips, cold-rolled steel sheets and strips.

Webster hardness testers are very suitable for use on the production sites. The testing takes less than one second. For instance, they can be used for on-the-machine hardness inspection of stainless steel strips, cold-rolled steel strips, copper strips without having to stop the production line.

Shenyang Tianxing Testing Instruments Co. Ltd., formerly Shenyang Tianxing Institute of testing Technology founded in 1993, has produced testing instruments for over 14 years. Our high quality products and reliable after-sale services have been widely recognized by our industrial customers. Many of our products have become dominant testing instruments in their fields in China, and many popular models have been shipped to wholesalers and customers abroad.

We have posted and will continue to post technical articles on metal hardness, hardness conversion tables, technical standards and other useful information for your reference. You are welcome to download these documents or request a brochure for free.
