A dissolved oxygen sensor is a detection device used to measure the amount of dissolved oxygen in the water.
Dissolved oxygen sensors are widely used in aquaculture, such as fish ponds, sewage treatment industry, hydrological monitoring, environmental monitoring, and in education and scientific research.
For aquaculture, if the DO level falls too low, the fish will suffocate as a consequence.

DO Sensor, RS485 output supports MODBUS, which can realize network and system integration without a driver.
There is no electrolyte, no interference, and no need for frequent calibration.
No oxygen consumption, no flow limit.
Built-in temperature sensor, automatic temperature compensation.
The water filter membrane, will not adhere to contaminants in the water.
Good stability, high measurement accuracy, and fast response.
