GGC-12E intelligent water-cooled COD reflux digestion instrument

Usage Instructions：

Chemical Oxygen Demand (COD) is a mandatory measurement in water bodies such as surface water, industrial wastewater, and domestic sewage,It is an important indicator reflecting the pollution status of water quality by oxygen consuming substances, and is also one of the key indicators for implementing total emission control. And the "Determination of Chemical Oxygen Demand in Water Quality - Dichromate Method"（HJ828-2017）It is currently recognized as a relatively accurate and reliable detection method for measuring results. However, the reflux digestion process of water samples is a process with strict temperature and time control, and poor control can lead to deviations in the analysis results.

Our company has extensively listened to the opinions of users and launched this instrument in accordance with the HJ828-2017 method. By using temperature controlled electric heaters instead of high-power electric furnaces for heating, automatic circulating water cooling instead of tap water cooling, automatic temperature control, 120 minute automatic countdown for micro boiling state, and automatic shutdown after digestion, the operation method is in line with the national standard method, with one click operation, automatic digestion, energy saving and consumption reduction, simple and convenient use, and also avoids technical disputes caused by non national standard COD measurement.

Technical advantages:

● Fully compliant with standards

The instrument design is completely based onHJ828-2017Determination of Chemical Oxygen Demand for Water Quality The standard of "Dichromate Method",comply withGB11914-89《CODDetermination of Dichromate Salt MethodAccurate temperature control, thorough digestion, and good parallelism;

● One click start, automatic resolution throughout the process, and unmanned operation

Just one click start, each digestion unit automatically heats up to the set temperature according to the set program, automatically counts down for reflux, and automatically stops heating;

● Uniform heating, thorough digestion, and visible operating parameters throughout the entire process

original creationPIDThe temperature control program ensures uniform heating and thorough digestion. The real-time heating temperature and remaining working time of each digestion unit can be monitored and changed in real time through a LCD screen.

● Humanized design, easy to operate

The reflux condenser tube can be automatically raised and lowered with one click, and the digestion area compartment is designed with a push-pull mechanism for easy access to digestion bottles. It also features a LCD touch screen for all functionsaloneThe operating parameters can be monitored in real-time throughout the entire process.
