Kelan Technology·THSHKELAN·Introduction

The team of Shanghai Kelan Instrument Technology Co., Ltd. (hereinafter referred to as Kelan) has been engaged in this industry since 1998. It is a company that has long been committed to research and development, manufacturingTechnology oriented sales and provision of technical servicesenterpriseThe company owns productsresearchSend designerAnd business management. The company's headquarters is located in Pudong New Area, Shanghai, and its branch is established in Wuxi High tech Park, Jiangsu Province.

Kelan Company implements standardized management system and insists on carrying out QC activities, conscientiously implementing national and industry standards; Standardized management and QC analysis management are implemented in all aspects of product design, production process, testing and inspection, as well as after-sales service.

Kelan Company focuses on continuous optimization of product technology, with product research and development departments including instrumentation, chemistry, and equipment renovation departments for power plant chemical water vapor systems. The Instrument Department is engaged in the research and production of instruments, while the Chemical Department develops sensor electrodes; Both primary and secondary meters have the functions of research and development, production, sales, and after-sales service.

Kelan instruments 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, cosmetics, medicine and hospitals, tap water, drinking water, swimming pools, aquaculture, education and research, etc. The product is suitable for monitoring or controlling the discharge of raw water (rainwater and seawater in Rivers and Lakes), high purity water, pure water, domestic water, general aqueous solution, surface water, reverse osmosis, industrial sewage and urban wastewater; Bioengineering high-temperature fermentation; Measurement and automatic dosing control of relevant solutions in industrial production processes.

The conventional instruments used by Kelan for measuring the quality of aqueous solutions include conductivity meters PH meter, ORP meter, dissolved oxygen meter, acid/alkali concentration meter, residual chlorine meter, turbidity meter, sludge concentration meter, interface meter, hardness meter, chloride ion meter, multi parameter meter, cabinet type, etc;

The series of large meters used in power plants include online sodium ion measuring instruments, silicate measuring instruments, phosphate measuring instruments, and hydrazine measuring instruments.

1、 Online industrial water analysis instrument: There are two series of conventional instruments

Kelan Conventional Instruments has developed three generations so far, and currently90 series and G055 series.

（1) 90 series: There are 2007 version and 2023Version, with various installation methods including explosion-proof type.

（2）G055 series: Starting from 2020, it is a newly developed instrument with mold property rights; 4.3-inch color display screen, capacitive touch buttons; Chinese and English menu software prompts for operation; Modular reliability design with functions such as recorders; The highlight is the composite type: it has single channel, multi-channel, and multi parameter combinations,namelyMeasuring the same parameter with one meter can achieve1 to 4 channels; It can measure and display 2 to 5 different parameter values, namely two parameters, three parameters, and five parameters.

2、 Sensors are the core components: multiple series are molded using our own molds

1）P026XXX pH Sensor Series: More than ten varieties are selected according to the characteristics of the measured medium, while continuously developing measuring electrodes for complex media to help users solve special on-site working conditions. The mass production of conventional triple composite pH sensors can provide long-term batch matching for instrument manufacturers.

2）High temperature disinfectable and sterilized electrode（DO dissolved oxygen and pH 130 ℃, used for biotechnology fermentation (reaction kettle fermentation tank);

3) ConductivitysensorSeries:There are four series of electrodes, including D602H, D2022T, D608F/P, and digital electrodes, which are made of different materialsMultiple ranges and structures to meet different on-site needs;

4）Residual chlorine sensor: It has a membrane covered universal and constant voltage principle;

5）Dissolved oxygen sensor: availableMg/L measurement and pure water ug/L measurement in power plants;

6）KL680X digital sensor series: including the use of fluorescence optical technology, without the need for a display instrument, directly with output current

4-20mA and RS485 communication interfaces can be directly connected to terminal display devices. Optical sensors include turbidity suspended solids, sludge concentration, interface meters, and fluorescence based dissolved oxygen; And digital series electrodes: pH, ORP, conductivity, residual chlorine, etc.

Kelan Company has submitted to1) More than 200 domestic and foreign coal power plants provide various chemical instruments and installation and commissioning services, including the renovation of chemical steam water sampling devices and the production of related equipment; 2) Supporting nearly 20 foreign projects, with regional distributors in Vietnam and Hong Kong; 3) We have provided over 50000 sets of online water solution monitoring, analysis, and control instruments and tens of thousands of sensor electrodes for more than 800 water treatment and environmental engineering projects in various industrial process fields.

The achievements of Kelan Company over the past 20 years are thanks to the support and assistance of our customers. We would like to express our gratitude! At the same time, we look forward to continuing pleasant cooperation with new and old customers at home and abroad, and working together to solve practical problems.
