24V RS485 Digital COD Meter For Measuring The Chemical Oxygen Demand
Brief Introduction
COD is an important indicator of organic pollution in water bodies, which can reflect the degree of pollution in water bodies. The higher the COD, the higher the content of reducing substances (organic matter) in the water body, and the reducing substances can reduce the content of dissolved oxygen in the water body, causing aquatic organisms to die from oxygen deficiency, and the water quality to decay and smell.
The DUC2-COD-H-D is a digital universal COD meter specially designed for the measurement of the chemical oxygen demand. It is a single parameter controller. A set of embedded software is pre-installed to adapt to different DRFN COD digital sensors;
2 high-precision 0/4~20mA current outputs with a maximum load of 1000 ohms;
The enclosure protection grade is IP66, can effectively isolate the pollution and corrosive gas from the external environment;
The COD meter has a two-wire RS485 interface, the communication protocol is MODBUS RTU, and supports JSON text data format;
DUC series COD meters can meet a variety of installation methods, such as wall-mounted installation, pipe clamp installation, panel installation, and provide accessories required for installation.
Advantages Of The COD Meter
Menu password can be set to facilitate user's data confidentiality;
Clock and historical data recording functions to meet higher data management requirements;
3.2-inch display screen and a 128*64 black and white graphic dot matrix LCD liquid crystal display, with reasonable interface settings and simple operation;
The display backlight of this instrument provides a choice of always-on and energy-saving modes, which users can set according to their needs;
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.
Users can query related information such as the working status and the serial number of the connected sensor via the analyzer.
Applications Of The COD Meter
River water, surface water, process water, sewage treatment plant, industrial wastewater, drinking water.
