沈陽天星
沈陽天星試驗儀器有限公司是專業生產便攜式硬度計的企業，我們生產的便攜式洛氏硬度計、表面洛氏硬度計、韋氏硬度計、里氏硬度計、渦流測厚儀等產品廣泛應用于金屬熱處理、淬火、金屬加工等行業，用于測試不銹鋼、鋼管、冷軋薄鋼板、鋼帶、鍍錫板、鍍鋅板、鋁型材、銅管、硬質合金、量具、刃具、刀具、沖壓件等產品。

PHR系列洛氏/表面洛氏硬度計改變了傳統的金屬硬度測試概念，可以象千分尺一樣使用，實現了硬度計的小型化、輕便化。儀器重量只有臺式硬度計的百分之一，精度與臺式硬度計相同。W-20系列韋氏硬度計主要用于測試鋁型材的硬度，也可測試銅管、銅板帶和經過熱處理退火的不銹鋼帶、冷軋板、冷軋鋼帶的硬度。韋氏硬度計十分適于在生產現場使用，特別適于在不銹鋼帶、冷軋鋼帶、銅帶的生產過程中對退火帶材產品進行不停機的在線硬度檢測，測試過程只需要1秒鐘時間。

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.
