    ST106BW intelligent water-cooled COD reflux digestion instrument
     
    Introduction:
    Chemical oxygen demand (COD) is a must-test item in surface water, industrial wastewater, domestic sewage and other waters. It is an important indicator reflecting the pollution of water quality by oxygen-consuming substances, and it is also one of the key indicators for the state to implement total emission control. One. The "Water Quality Determination of Chemical Oxygen Demand Dichromate Method" (HJ828-2017) is currently recognized as a more accurate and reliable detection method. However, the reflux digestion process of water samples is a process with strict temperature and time control, and poor mastery will cause deviations in the analysis results. 
    Our company extensively listens to users' opinions and introduces this instrument with reference to the HJ828-2017 method. The use of temperature-controlled electric heaters instead of high-power electric furnace heating, automatic circulating water cooling instead of tap water cooling, automatic temperature control, automatic countdown of 120 minutes in the micro-boiling state, automatic shutdown after digestion, etc., realize the operation method and the national standard method. Key operation, automatic digestion, energy saving and consumption reduction, simple to use and convenient to operate, but also avoids technical disputes caused by non-national standard method for COD measurement.
    Features:
    1. Fully comply with national standards
    The instrument design is completely based on the national standard HJ828-2017 "Water Quality Determination of Chemical Oxygen Demand Dichromate Method", with precise temperature control, thorough digestion, and good parallelism;
     2. One-key start, automatic digestion in the whole process, unattended
    With just one button to start, each digestion unit will automatically heat up to the set temperature according to the set program, automatically count down to reflux, and automatically stop heating;
     3. The heating is uniform, the digestion is complete, and the operating parameters are visible throughout the process
    Original PID temperature control program, uniform heating, complete digestion, the real-time heating temperature and remaining working time of each digestion unit can be monitored through the LCD display and change in real time.
     4. Humanized design, easy to operate
    The reflux condenser can be raised and lowered automatically with one button, the digestion zone is designed to push and pull, and the digestion bottle is easy to take out. The 7-inch LCD touch screen is on the right side, and all partition operating parameters can be monitored in real time throughout the process.
