<p>Founded in 1992, Chengdu Zhenghua Electronic Instrument Co., Ltd. is a professional enterprise engaged in R&D and manufacturing of vacuum measurement products. It integrates scientific research, development, processing, manufacturing, sales and service, specializing in vacuum measurement products and auxiliary equipment. The products are widely used in vacuum measurement and control of various vacuum application equipment. After more than 20 years of development, it has achieved a leap from vacuum measuring instruments (vacuum gauges) to vacuum gauge tubes and then to vacuum transmitters. Currently, it has three major product categories: vacuum measuring instruments (vacuum gauges), vacuum transmitters, and vacuum gauge tubes. Guided by market demand, the company has developed about 20 series and 30 specifications of digital and networked vacuum gauges, making it one of the domestic manufacturers with the most complete varieties and specifications. The successful development of vacuum transmitters marks a new measurement mode, overturning the traditional need for gauge tubes to be matched with vacuum gauges. With the adoption of PLC controllers and LCD touch screens in vacuum equipment, installing vacuum transmitters at system detection points and directly connecting to PLC controllers completes vacuum measurement and control, simplifying the system and improving stability. Over the past two decades, the company has developed and produced general-purpose 'Chengzhen' brand vacuum gauge tubes, several of which have obtained patent certificates, becoming a manufacturer with rich varieties and specifications in China. The company adheres to the value concept of 'technological innovation, excellent quality, perfect service' and is willing to establish long-term cooperation with customers in an open, flexible and responsible manner to jointly improve domestic vacuum measurement technology and build corporate reputation and brand.</p>
