Shanghai Qingmiao Optoelectronic Technology Co., Ltd. is located in the Greater Zhangjiang area of Pudong. It gathers multidisciplinary professionals in the fields of optics, electrochemistry, electronics, software, communication, environmental protection, automation, and intelligent control. After nearly a decade of research and development accumulation, it has formed core technologies in online water quality instruments and system integration.

Shanghai Qingmiao Optoelectronic Technology Co., Ltd. registered the trademark "Qingmiao Measurement and Control", which reflects the development direction of combining online measurement technology with wireless remote control technology, integrating big information technology with industrial technology equipment, and achieving lean and intelligent process production.

Through intelligent process control algorithms, feedforward and feedback form closed-loop control, realizing data-driven, real-time, automated, and cloud based processes that were previously controlled by experience.

Based on years of practical experience, a three-tier technology product has been developed with water quality sensors, communication transmission, and intelligent control cloud computing platform as the core, which has been integrated into a comprehensive water quality cloud computing system integration platform.

Widely used in environmental monitoring, circulating water measurement and control systems, water supply and drainage monitoring and control systems, and industrial aquaculture systems.

Shanghai Qingmiao Optoelectronics Technology Co., Ltd. implements a multi parametric, serialized, differentiated, and integrated product strategy in sensors and online analytical instruments.

Differentiated Product Strategy: Online Standard Five Parameters ph、 On the basis of conductivity, dissolved oxygen, and ORP instruments, we will focus on developing online low range turbidity meters, residual chlorine analyzers, ammonia nitrogen analyzers (ion selective electrode method), blue-green algae sensors, chlorophyll sensors, and water oil sensors.

Multi parametric product strategy: Dissolved oxygen multi parameter analyzer (Do, pH, temperature), ammonia nitrogen multi parameter analyzer (ammonia nitrogen, pH, temperature).

Series product strategy: Disinfection process control series and water oil sensor series

Disinfection process control series: residual chlorine, total chlorine, chlorine dioxide, ozone analyzer, covering the main disinfection field process control instruments.

Water oil sensor series: ppb level water oil sensor for surface water, ppm crude oil water oil sensor, ppm refined oil-water oil sensor.

Integrated product strategy: Wireless measurement and control system for circulating water, with cooling circulating water treatment equipment as the core, integrating online monitoring of pH, conductivity, hardness, turbidity, temperature difference, etc., controlling water pump circulation and fan cooling to achieve remote unmanned energy-saving and emission reduction of cooling circulating water
On duty control.
