We are a long-term company dedicated to research and development, manufacturingTechnology oriented sales and provision of technical servicesenterpriseThe company has product development capabilitiesdesigner：electronlineHardware and softwareProgrammingAnd analytical chemistry engineers; Having business managementAt the same time, we have long-term exchanges and cooperation with foreign technology companies.

Kelan Company has its own standardized management system and insists on carrying outQC activities. The product complies with the national and industry standards of the People's Republic of China，Using international standards to develop enterprise standards; Implement standardized management in all aspects from product design, production process, to factory inspection and after-sales serviceQC management.

Kelan Company attaches great importance to the continuous improvement of technological products and has established an instrument department and a chemical department in product research and development. The Instrument Department is engaged in the design of instruments, while the Chemical Department specializes in the research of sensor electrodes. It is one of the few technology companies in the industry that has research and development capabilities for both primary and secondary meters.

Kelan's product equipment and sensor electrodes are widely used in power plants, petroleum, chemical, aluminum, metallurgical steel, mining, coking, electroplating, semiconductors, printing, papermaking, textile industry, wine industry, food and beverage, pharmaceutical hospitals, tap water, drinking water, swimming pools, aquaculture aquatic products, biotechnology high-temperature fermentation, education and scientific research, etc. The product is suitable for monitoring or controlling raw water (rainwater and seawater in Rivers and Lakes), high purity water, pure water, domestic water, general aqueous solution and surface water, water used in various industrial production processes, reverse osmosis, industrial sewage and urban wastewater discharge, etc.

Kelan has a wide range of water quality measurement products,oneInstrument productsHaving high, medium, and low gradesAnd configurationSuitable for the needs of different users. With the continuous improvement of user technical requirements, we have developed three generations of products,★2007Since the beginning of the year, it has been put into the market90 seriesOnline water analysis instruments belong to the second generation, including conductivity metersPH meter, ORP meter, dissolved oxygen metersour/Alkali concentration meter、Residual chlorine meter, turbidity meter, sludge concentration meter, interfaceInstrument, hardness tester, chloride ion meter, andMulti parameter instrumenthaveCOD、 Ammonia nitrogen,Total phosphorus, etc; Used by power plants, etcSodium ion measuring instrument, silicate measuring instrument, phosphate measuring instrument, hydrazine measuring instrumentWait.

★2019Since the beginning of the year, we have comprehensively optimized our products and developed a batch of measurement products that meet modern technological requirements.G055 Series of water quality measuring instruments for investmentautonomousThe newly developed generation of instrumentsIt belongs to the third generation product of our companyIt reflects the contemporary domestic moisture contentAnalyzing the level of instruments, there aresingle channel★ Multi channel ★ Multi parameterModular design allows for arbitrary combination and connection.

2、 Sensor electrodeIt is the core part of the instrument, and we have invested in research and development for optimization, forming multiple series of molds.

Conductivity electrode series: with multiple ranges and installation structures;

■P026XX series pH electrode,More than ten varietiesThere are multiple options for application in different tested media and situations;

■The electrode of the 130 ℃ high-temperature sterilization sensor (dissolved oxygen and pH) is used for the fermentation tank of the bioengineering reactor.
■The KL680X digital sensor series adopts optical technology and does not require a display instrument. It directly has a 4-20mA output current and RS485 communication interface. By connecting to terminal display devices such as computers, it can measure display data to meet different needs.

threeChemical instrumentation for power plants：Kelan Company has been providing various water analysis and measurement instruments as well as installation and commissioning services to domestic and foreign power generation companies for 20 years. At the same time, it undertakes the renovation of power plant steam and water sampling devices and the production and provision of related equipment.
