Guangzhou Yangcheng Science & Technology Enterprises Co., Ltd.
was established in 1987. We are a multi-industry enterprise group
with several hundred million RMB of annual sales in the industries
of electrical measuring equipment, industrial and domestic
automation engineering, biology engineering, and business trade. We
have 464 employees today, among which 156 staffs engaged in the
manufacture and business of electrical measuring equipment.
In 2002, the electric measurement department of the company
separated and set up a wholly-owned subsidiary Guangzhou GENY
Electric Co., Ltd. It is a Hi-Tech company specialized in electricity measuring equipment.
Nowadays, we are one of the biggest and leading manufacturers of
electrical measuring equipment in China. We have sold more than
7000(Seven Thousand) sets of energy meter test benches and more
than 10000(Ten Thousand) sets of portable calibrators in the China
market so far.
In the domestic market of electric measurement products, our
marketing occupation share is around 30%. Many state-owned
large-sized utilities and power-supply bureaus are our constant
clients. It is due to the excellent quality of our products and the
good after-sales service that we offer.
During the past years, we have made great efforts in exploring the
overseas market, which yielded fruitful results. Today our products
reached many places in the world(over 30 countries)and our important customers include Actaris, Landis&Gyr, EATON, Schlumberger, Secure Meters, EMCO, NAMJUN, LEMZ, etc.
