BDO-320 dissolved oxygen/temperature sensor

• Introduction

The dissolved oxygen sensor uses fluorescence method to measure dissolved oxygen. The emitted blue light shines on the fluorescent layer, and the fluorescent substance is excited to emit red light. The oxygen concentration is inversely proportional to the time it takes for the fluorescent substance to return to the ground state. By using this method to measure dissolved oxygen, there will be no oxygen consumption during the measurement, the data is stable, the performance is reliable, there is no interference, and the installation and calibration are simple.

• feature

The sensor adopts a new type of oxygen sensitive membrane, which has good repeatability and stability; Breakthrough fluorescence technology with low maintenance costs; Hard texture, fully enclosed design, improves durability; Small drift, fast response, and reliable results; The on-site installation of sensors is convenient and fast, achieving plug and play functionality; Can be calibrated directly in the air without the need for zero point calibration; Default RS485 communication interface, standard Modbus protocol for easy integration.

• application

Widely used for dissolved oxygen monitoring in sewage treatment plants, water treatment plants, water stations, surface water, aquaculture, industry and other fields.
