A classic case of Anhui Zhongke Intelligent High-tech Co., Ltd.

Since 1992 successfully developed the first intelligent leak detector with independent intellectual property rights, through the unremitting efforts of the company's technicians, the sealing performance testing products have formed a series of products with many varieties, models and functions from low pressure, medium pressure to high pressure. There are differential pressure and flow detection methods, among which the high-pressure leak detector is the "Tenth Five-Year Key Project" undertaken by our company in Anhui Province, and passed the acceptance of experts in 2004.

This series of products have won the national new products, the second prize of scientific and technological progress in Anhui Province and the second prize of excellent products of the provincial government.

Four patents have been applied for this series of products, and one invention patent has been authorized. From 65438 to 0988, our company successfully developed the first accelerated elevator test in China, which rewrote the history that there was no special elevator safety testing equipment in China and promoted the development of the industry. In the field of elevator operation safety detection, in order to meet the market demand, the company successfully developed the first portable speed limiter tester in China on 1995. These two devices have become necessary measuring instruments for national quality and technical supervision institutions and special equipment inspection institutions.

In 2005, the speed limiter tester and elevator acceleration tester were approved by the Ministry of Science and Technology as the supporting units of the national key promotion plan of scientific and technological achievements. In 2006, the company successfully developed DGZ wire rope tensile testing machine.

Seven patents have been applied for this series of products, including 2 invention patents, 5 authorizations and 2 authorizations.
