Product presentation
The pre-treatment process is automatically completed, and the patented color sensor is used to determine the end point of the titration, which is in full compliance with the "Determination of Water Quality Chemical Oxygen Demand Dichromate Method" (HJ 828-2017).
Product Features
The fully automatic analysis of high and low concentrations of chemical oxygen demand in wastewater, surface water and groundwater meets the requirements of the "Water Quality Determination of Chemical Oxygen Demand Dichromate Method" (HJ 828-2017). 105 sample trays and a special flow path system, 16 samples are automatically analyzed at the same time, with all the steps involved in manual experiments such as automatic sampling, liquid addition, heating and digestion, cooling, dilution, titration, etc., which can completely complete the operation of the experimenter. While ensuring the efficiency of sample analysis, save manpower to the greatest extent. The simulated human eye recognition is completely consistent with the classic manual method (human eye recognition), which eliminates the problems of low sensitivity and susceptibility to interference in the single-wavelength photometric method. The unique artificial intelligence AI algorithm automatically uses color mutations to determine the titration end point, which can realize the artificial synchronization judgment and comparison of the titration process. The temperature and time are precisely controlled to ensure the consistency of sample digestion. The temperature control accuracy of each digestion tube is ±1℃, and the digestion time is 2 hours. Record the whole process of experimental parameters and result information, with strong traceability and complete quality control methods. Product performance indicators meet HJ 828-2017 requirements
