Aquarium do online digital dissolved oxygen meter analyzerRelated product

Description

Dissolved Oxygen Meter is one of the intelligent online chemical analysis instruments. It is widely used in continuous monitoring of dissolved oxygen, saturation, oxygen partial pressure and temperature .The continuous monitoring data is realized by remote transmission monitoring and recording through the transmission output connection recorder. It can also be connected to the RS485 interface and can be easily connected to the computer for monitoring and recording through the MODBUS-RTU protocol.
