Our Company

Yancheng Aoding Instrument Manufacturing Co., Ltd. is located in the beautiful and rich coastal city.Since it established, the company has cooperated with famous universities and research institutes in Jiangsu, Shanghai and other places.

From the components to the final assembly, the factory has gone through strict screening and process quality control, ensuring that the products can be operated safely, reliably and with high quality to the user. The goal we have been pursuing: accurate product measurement, reliable operation, simple operation, low maintenance, little spare parts, convenient installation and good service.

Our products in the global market has been used successfully for more than 10 years, as the industry leader, we will continue to provide a reliable instrument and professional services to global customers, and constantly improve the technological innovation and product quality to meet the needs of different customers.

Product Description

DO-6383YG dissolved oxygen sensor adopt fluorescence measurement of dissolved oxygen and emit blue light on the screen. The fluorescent substance is stimulated to emit red light. The oxygen concentration is inversely proportional to the time when the fluorescent substance returns to the ground state. The dissolved oxygen measured by this method does not produce oxygen consumption when measured, the data is stable, the performance is reliable, the interference is not exist, the installation and correction are simple.

The product is widely used in wastewater treatment plants, waterworks, water stations, surface water, aquaculture, industrial and other fields of dissolved oxygen monitoring. The configured waterproof high-performance controller can easily receive the data measured by the sensor. The user can also realize the 4-20mA analog output through the interface configuration and calibration of the controller. It realize relay control, digital communication and other function.
