MODBUS RTU Digital Universal Dissolved Oxygen Tester For The Measurement Of DO
Brief Description
The molecular state of oxygen dissolved in water becomes dissolved oxygen, usually noted as DO, expressed in milligrams of oxygen per liter of water. The amount of dissolved oxygen in water is an indicator of the self-purification ability of the water body.
DUC series dissolved oxygen digital universal controller, is a single parameter controller, within each dissolved oxygen tester, 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 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 tester has 2 settable SPST multi-function relays and 2 high-precision 0/4~20mA current outputs.
Separate controller and sensor setup lists are available for a quick and detailed list of the configuration parameters set.
The interface of the dissolved oxygen tester is a two-wire RS485.
The dissolved oxygen digital universal controller has the salinity and air pressure compensation function.
Applications
Aquaculture industry, sewage treatment plant, boiler feed water, condensate, and other industrial industries.
