Yueqing Liushi Hongxing Instrument Factory specializes in manufacturing temperature controllers, refrigeration controllers and digital time relays. Hongxing was established in 1997. Since 1997, our products (especially temperature controllers) have consisted of more than 60 series in more than 500 specifications. Hongxing products are exported to more than 70 countries and regions, and the good quality of Hongxing products is recognized by users globally.Hongxing Instrument Factory has advanced manufacturing and testing equipment. In particular, Hongxing pays attention to the development of technology; Hongxing's 'Research and Development Center' has a very effective and efficient engineering team. In our two sub-departments under the R&D center, more than 80% of engineers hold senior engineer certificates. During product design, all engineers use computer assisted design software such as CAD, ProE, Protel, and EDA, and we fully use micro-processors (Motorola, Microchip, Atmel, and Philips chips) to design products, to boost product performance and quality. Hongxing has passed ISO9001:2000 quality system certification, CE certification and RoHS certification, and we have passed the National Food Industry standard, National Food Machinery Quality Inspection Committee Center certification, and Product Quality Inspection of Guangzhou certification. Since 1998, Hongxing has carried out the 'Based-MCU PID Temperature Controller Project'. The PID series controllers have high precision and accuracy in measurement and control, and high stability, and they have been favored by users. Hongxing is dedicated to becoming the leader in the temperature control field. We have developed series of temperature controllers, humidity controllers, time relays, current and voltage meters, pressure meters, flow meters, counters, and temperature and humidity sensors.Hongxing holds strong technical design capabilities, developing high-performance automation and control products. With the spirit of "Looking forward to the future, Creating the brilliant brand of Hongxing", we will supply higher quality products and better services to global customers, and warmly invite all customers to visit Hongxing!
