Brief Introduction
COD (chemical oxygen demand) is a commonly used comprehensive index to evaluate the degree of water pollution. It refers to the amount of oxygen consumed by chemical oxidants (such as potassium dichromate) to oxidize and decompose reducing substances (such as organic matter) in water. It reflects the degree of pollution of the water body by reducing substances.
The DUC2-COD-H-A is a digital analyzer specially designed for the measurement of COD. 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 digital online COD analyzer for wastewater treatment has a two-wire RS485 interface, the communication protocol is MODBUS RTU, and supports JSON text data format;
Mounting method: Wall mounting, pipe clamping, panel installation (hole size 138*138 mm).
Advantages Of The Online COD Measuring Instrument
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.
Applications Of The Online COD Measuring Instrument
River water, surface water, process water, sewage treatment plant, industrial wastewater, drinking water.
