model：jx-c7048
brand：shanghai jingxin
specifications ：set
introduction：it is suitable for the determination of chemical oxygen demand (cod) in surface water, domestic sewage and industrial wastewater. it is suitable for the analysis of a large number of environmental samples and has good application and promotion value.
product description：
water quality cod automatic intelligent analysis workstation jx-c7048, automatic sample processing, no need to manually transfer samples. avoid contact with harmful substances such as mercury, potassium dichromate, and concentrated sulfuric acid. intelligent location identification, intelligent process control, intelligent observation of results, automatic processing of reports and uploading to the lims system. in full accordance with the "hj828-2017" standard. the independent pipeline is used to add liquid to prevent cross-contamination; the graphite is heated, and the sample response is consistent; the use of human eye bionic design, digital processing of color changes makes color judgment more accurate
application: it is suitable for the determination of chemical oxygen demand (cod) in surface water, domestic sewage and industrial wastewater. it is suitable for the analysis of a large number of environmental samples and has good application and promotion value.
fast titration: with the new bionic color titration method, results can be obtained quickly and accurately.
machine memory function: after power off, restart the software, the software will judge the status of the experimental task by itself and continue to complete the task until the end of the experiment.
software humanization function: task pause and task continuation can be turned on at any time during the experimental steps, which is more suitable for users' usage habits.
stable performance: the gantry structure is adopted, which completely avoids the problems of poor repetitive positioning, falling cups, and colliding cups of existing products on the market.
automatic calibration function: automatically add various reagents to calibrate the concentration of ferrous ammonium sulfate.
chloride coarse measurement function: use a simple and fast way to estimate the chloride ion content in water samples.
sample addition: samples can be added at any time without waiting for the end of the experiment.
sample information import function: quickly import sample information, avoid individual editing of sample information, and improve work efficiency.
overall sealing: perfect protection measures to avoid injury from harmful gases and hardware movement in the experiment. the overall sealing avoids the pollution to the environment during the test process, and also avoids the environment to cause pollution to the experimental process.
