chongqing sonny rohl instrument co., ltd (Chongqing Sunflower Instrument co,. ltd) is a focus on thermometer, pressure gauge, sensors and other instrumentation research and development, production, sales of enterprises. The company is located in Beibei District, Chongqing City, which has the title of China's instrument town. Main products include: industrial bimetal thermometers, pressure thermometers, pressure gauges, thermocouple thermal resistance temperature sensors, temperature transmitters, pressure transmitters, level gauges, flow meters, heat sleeves, oven bimetal thermometers, fireplace thermometers, refrigerator refrigerated thermometers, agricultural and horticultural compost bimetal thermometers, etc. The instruments and meters produced by our company are widely used in metallurgy, petroleum, chemical industry, cement, electric power, machinery and laboratory, as well as our daily life and other fields. Our company has the right to import and export, products are exported to Europe, the United States, Australia, Russia, Mongolia, Indonesia and other countries in Southeast Asia.

In recent years, our company has successfully developed 1350 ℃ high temperature thermocouple (metal alloy) for some special application environments such as high temperature circulating vulcanizing bed (CFB) boiler, cement high temperature kiln, anode baking furnace, vaporization furnace, high temperature furnace, forging furnace, sintering furnace (brick/lime, etc.), pulp/paper recovery high temperature furnace, etc, 1200 ℃ wear-resistant thermocouple (metal alloy), high temperature corrosion-resistant thermocouple (corrosion-resistant thermocouple), high temperature wear-resistant corrosion-resistant thermocouple, corrosion-resistant thermocouple, high pressure thermocouple, thermocouple for temperature measurement of aluminum-zinc-copper solution,(CFB) wear-resistant thermocouple for circulating vulcanizing bed, wear-resistant thermocouple for cement rotary kiln, thermocouple for anode roasting furnace, thermocouple for high temperature hot blast furnace, thermocouple for vaporization furnace, thermocouple for carburizing furnace, thermocouple for copper, iron and molten steel, anti-oxidation tungsten rhenium thermocouple, thermocouple for vacuum furnace, Pt100 wear-resistant platinum thermal resistance, corrosion-resistant platinum thermal resistance, K-type nickel chromium-nickel silicon thermocouple, S-type single platinum rhodium thermocouple, R-type platinum rhodium-platinum thermocouple, B- type double platinum rhodium thermocouple and other special thermocouples to meet the needs of various harsh environments such as high temperature, high pressure, corrosion and wear. According to different pressure use environments, our company has developed bellows pressure gauges, vacuum pressure gauges, spring tube pressure gauges, diaphragm pressure gauges, safety pressure gauges, explosion-proof pressure gauges, differential pressure gauges, etc. According to different installation environments, we have developed axial bimetal thermometers, radial bimetal thermometers, universal bimetal thermometers, sanitary bimetal thermometers, flange mounting thermometers and thread mounting thermometers. For long-distance field display requirements, we have developed a 1-25m ultra-long capillary thermometer. In view of the corrosion-resistant environment, our company has corrosion-resistant bimetal thermometer, corrosion-resistant pressure gauge and corrosion-resistant temperature sensor. Product support customized, as far as possible to meet the requirements of different customers on the spot.
