目前，在电解槽铁碳模块组装质量的检测都是通过用直流焊机通入大电流测试的方式进行估量，因为电流输出不稳定。所以测量结果不能直观反应模块的组装质量。由我公司与中铝公司共同研制生产的高精度铁碳压降测试仪采用新型电力电子技术，电流输出大，可达到1000A的大电流。仪器采用7寸触摸屏。智能化操作。用户只需要设置测试电流，仪器通过程序自动恒流输出大电流。当达到所设置的电流后，设备自动测量出模块的电阻及模块的电压降，从而快速准确的判断出模块的组装是否合格。

电解槽电极(阳极炭块、阴极炭块）质量的好坏，电解槽投产后的各项经济指标影响较大。在组装电极时，由于材料本身的差异（主要是阴极糊料、磷生铁），或者组装工艺、组装人员组装水平的差异，zui终造成电极组装质量的巨大差异。组织质量不好的电极，其电阻较大导电能力差，在后期生产过程中的损耗就高，从而造成大量的电能白白的浪费，降低工厂的经济效益。另外提高电极钢棒头的焊接质量，减小焊缝的压降同样具有节能降耗的重大意义。

PRS-200T铁碳压降测试仪可以直接测得电极组装后的电阻及压降，并在液晶屏上显示出实验电流、电阻、电压降。该仪器测量准确、操作方便、性能稳定，是一款针对性很强的仪器。用户通过该仪器可以及时、方便的掌握电极组装后的详细数据，从而判断组装质量的好坏，以便于及时修正组装材料或者修改组装工艺，加强组装质量的控制工作。

PRS-200T高精度铁碳压降测试仪可以直接检测铁碳模块（阳极炭块、阴极炭块）及钢棒头焊接的组装质量，从而选用合格的铁碳模块可以为用户节约了大量的电费。采用定制的测试线及测试夹具，让测试更加方便、快速。减小了一线工人的工作量。

At present, the testing of quality of electrolytic cell Iron carbon module assembly is estimated by DC welder with big current test for the current output is unstable. Therefore, the measurement result cannot directly reflect the assembly quality of the module. The anodic casting quality tester developed and produced by our company and Aluminum Corporation of China adopts the latest power electronic technology with big current output which up to 1000A. The instrument adopts 6 inch touch screen LCD. Intelligent operation. The user only needs to set the test current. The instrument will automatically output big current through the program at constant current. When the set current is reached, the device will automatically measure the resistance and  the voltage drop of the module. So as to quickly and accurately determine whether the assembly of the module is qualified .

The quality of electrode, anode carbon block and cathode carbon block, of electrolytic cell is good or bad will greatly affect various economic indexes after the electrolytic cell is put into operation. In the process of electrode assembly, due to the differences in materials which mainly cathode paste and phosphorus iron or the differences in the assembly process and the assembly level of the assembler, the quality of electrode assembly will be eventually vary greatly. The electrode with poor organization quality has a relatively large resistance and poor conductivity, which will lead to high loss in the later production process resulting in a large amount of wasted electric energy and reducing the economic benefits of the factory. In addition, it is also have great significance of energy saving and consumption reduction to improving the welding quality of electrode steel rod head and reducing the pressure drop of welding seam.

The instrument can directly measure the resistance and voltage drop after electrode assembly and display the experimental current, resistance and voltage drop on the LCD screen. The instrument is accurate in measurement, easy to operation and stable in performance, which is a highly targeted instrument. Through this instrument, users can timely and conveniently grasp the detailed data after electrode assembly. So as to judge the quality of assembly is good or bad, which can strengthen the control of assembly quality by modify the assembly materials or process timely.

PRS-200T anode casting quality tester (iron carbon pressure drop tester) can directly detect the casting quality of iron carbon modules (anode carbon block and cathode carbon block) and the welding quality of steel rod head, so the selection of qualified iron carbon modules can save a lot of electricity for uses. customized special test wire and test fixture will be adopted to make the test more convenient and fast. It reduces the workload of the front-line workers.

Anodic casting quality tester (iron carbon voltage drop tester) is suitable for high precision measurement of iron carbon module combination and voltage drop and other testing occasions requiring big current, small resistance and low voltage, such as steel bar welding quality test.

1. Test current: It could adopt the biggest DC constant current source up to 200A which customizable below 2000 A to make the measurement results more accurate. It adopts the most advanced power technology, which can be stable output for a long continuous time. And thus overcome the pulse power only instantaneous output which resulting in inaccurate test data.

2. Display mode: Current, resistance and voltage will be displayed by six half color LCD.

3. Strong anti-interference capability The use and measuring precision of the instrument can not be affected under the magnetic interference environment even though in the strong magnetic interference environment of electrolytic aluminum plant.

4. High intelligence This instrument adopts ARM control with the functions of date clock, data storage, automatic printing and so on. The instrument will control the output automatically.

5. The test speed is fast. The test of time is only 3 seconds for once. This can improve the work efficiency.

6. Easy to use: The operation interface is simple and the measurement data is intuitive. The built-in paper front change printer can print the data in Chinese.

7. Long service life: The LCD with wide temperature line Chinese is adopted to solve the problem that LCD is easy to fail in high position and direct sunlight environment. All components adopt high precision resistance to effectively eliminate the influence of ambient temperature on the measurement results. The use of aviation connectors enhances the anti-vibration performance.
