Weihai tiangang instrument co., Ltd. Founded in 1993, with a registered capital of 40 million Yuan, is a company specializing in heat meters ( cold and heat meter ) research and production enterprise. the company has a strong technical force of the scientific research team, a complete set of modern management systems, as well as the manufacturing of advanced equipment and excellent technology. years company always adhere to the "quality first, reputation first" principle, after a positive innovation, industry pioneer, has developed into a fixed assets of more than 35 million Yuan, plant more than 3,000 square meters of heat meter manufacturer.

company since 1999 started producing heat meters, has developed a single-stream, stream and ultrasonic calorimeter, and make the corresponding production permit, in 2004 the company passed 9,001:2008 quality management system certification ISO, 2005 I self research and manufacturing of heat flow measuring device to inject 500 m³/hour, This is the first domestic large-diameter heat flow measuring device, 2008 heat meter products produced by our company successfully through the CE certification, in 2009 our company production of reflection type ultrasonic heat meter, and no magnetic flux heat meters and passed the construction Department of Shandong province new product identification. the following is my company's product development process:
