CS4773D Digital Dissolved Oxygen Sensor
Dissolved oxygen sensor is a new generation of intelligent water quality detection digital sensor independently developed by twinno. Data viewing, debugging and maintenance can be carried out through mobile APP or computer. Dissolved oxygen on-line detector has the advantages of simple maintenance, high stability, superior repeatability and multi-function. It can accurately measure DO value and temperature value in solution. Dissolved oxygen sensor is widely used in wastewater treatment, purified water, circulating water, boiler water and other systems, as well as electronics, aquaculture, food, printing and dyeing, electroplating, pharmaceutical, fermentation, chemical aquaculture and tap water and other solutions of the continuous monitoring of dissolved oxygen value. -
CS4760D Digital Dissolved Oxygen Sensor
Digital Dissolved Oxygen Sensor based on the fluorescence method is a modern, high-performance sensor for continuous DO measurement in water and wastewater. Unlike traditional polarographic or galvanic sensors, it uses an optical principle: a luminescent material is excited by blue light, and the decay time or intensity of the emitted red light is directly related to the oxygen concentration. This method requires no electrolyte, no membrane replacement, and has no oxygen consumption, significantly reducing maintenance and calibration frequency. The sensor features a built-in digital output (RS-485, Modbus RTU), automatic temperature and pressure compensation, and anti-interference design for stable readings even in low-flow or low-oxygen environments. It is widely used in aquaculture, municipal wastewater treatment, surface water monitoring, and industrial process control. With its durable construction, fast response, and long-term stability, the fluorescence DO sensor ensures accurate and reliable online monitoring for critical water quality management.
