Jiangsu zhaolong electrical instrument co., LTD. / Shanghai dragon electrical appliance co., LTD is a professional engaged in the temperature sensor and temperature control instrument production enterprise, is a high-tech enterprise and local brand products, together with the Shanghai university of science and technology development and production of series of thermocouple (resistance) and temperature control electronics. Development of the wireless transmission and measuring temperature control; Company in 2000 through the IOS9001:2000 quality system certification and CE certification. The company independent research and development of energy-saving ac contactor has obtained national invention patent and utility model patents, and 3 c compulsory certification. This product has good energy saving effect, long service life, no noise, walk in front of industry, and participated in the national "ac contactor allowable value of energy efficiency and energy efficiency grade standards, GB21518-2008 standard, is mainly involved in enterprise. Enterprises have a first-class production lines and testing means, implement the whole process of quality supervision. The enterprise has a strong technical development team and patent. Participated in the Shanghai world expo in 2010, is the only enterprise in electric instrument industry. Products include: WR series of thermocouple, WZ series thermal resistance and thermocouple (patent), all kinds of anti-corrosion explosion-proof thermocouple (explosion-proof certificate), wear-resistant thermocouple (patent), armoured thermocouple, thermocouple, end thermocouple, pressure spring integration heat resistance thermocouple. Recently, my company also developed a thermocouple used under special conditions, such as steel, aluminium, zinc, copper water solution such as water and salt bath furnace temperature measuring thermocouple; Cement plant and power plant using thermocouple under special circumstances, high precision, long service life; New anti-oxidation tungsten-rhenium thermocouples, low cost, high temperature, is an ideal product to replace platinum rhodium thermocouple, some products reach the military level. In 2013 the company obtained the national explosion-proof explosion-proof thermocouple, heat resistance production qualification certificate, certificate of national standardization good behavior, province private scientific and technological enterprises and 3 a to ensure conformity confirmation certificate.
