Digital Universal Dissolved Oxygen Instrument Tester With Salinity Compensation
Brief Description
Dissolved oxygen is closely related to the partial pressure of oxygen in the air, atmospheric pressure, water temperature, and water quality. Dissolved oxygen value is a basis for the study of the self-purification ability of the water body.
DUC series dissolved oxygen digital universal analyser, is a single parameter controller, within each dissolved oxygen analyzer, a set of embedded software is pre-installed to adapt to different dissolved oxygen digital sensors. By accessing different types of dissolved oxygen digital sensors, to achieve the measurement needs of different scenarios.
The connected sensors upload the detected data in a special encrypted communication method to ensure that the DUC controller can collect high-precision data in a more stable manner. The DUC displays the collected data on the controller's display in real-time for easy reading by the user.
The protective grade of the DUC dissolved oxygen instrument shell is IP66, which can effectively isolate the pollution of the external environment and the invasion of the corrosive gas. Rich output configurations are available to meet the different detection needs of many applications.
Product Advantages
The dissolved oxygen instrument configure with RS485
Modbus RTU, RS485 allows multiple devices to be connected to
the same bus and perform data transmission and control through
serial communication protocols, making the integration between
devices simpler and more flexible. RS485 uses differential signal
transmission, which can resist electromagnetic interference in
industrial environments and ensure stable data transmission. RS485
can support relatively long communication distances, allowing
devices to be distributed in distant locations while maintaining
reliable communication.
The dissolved oxygen analyser has 2 settable SPST multi-function relays and 2 high-precision 0/4~20mA current outputs.The interface is a two-wire RS485.
The dissolved oxygen digital universal instrument has the salinity and air pressure compensation function.
Applications
Aquaculture industry, sewage treatment plant, boiler feed water, condensate, and other industrial industries.
