目前，在電解槽鐵碳模塊組裝質(zhì)量的檢測都是通過用直流焊機通入大電流測試的方式進行估量，因為電流輸出不穩(wěn)定。所以測量結果不能直觀反應模塊的組裝質(zhì)量。由我公司與中鋁公司共同研制生產(chǎn)的高精度鐵碳壓降測試儀采用新型電力電子技術，電流輸出大，zui大可達到1000A的大電流。儀器采用7寸觸摸屏。智能化操作。用戶只需要設置測試電流，儀器通過程序自動恒流輸出大電流。當達到所設置的電流后，設備自動測量出模塊的電阻及模塊的電壓降，從而快速準確的判斷出模塊的組裝是否合格。

電解槽電極(陽極炭塊、陰極炭塊）質(zhì)量的好壞，電解槽投產(chǎn)后的各項經(jīng)濟指標影響較大。在組裝電極時，由于材料本身的差異（主要是陰極糊料、磷生鐵），或者組裝工藝、組裝人員組裝水平的差異，zui終造成電極組裝質(zhì)量的巨大差異。組織質(zhì)量不好的電極，其電阻較大導電能力差，在后期生產(chǎn)過程中的損耗就高，從而造成大量的電能白白的浪費，降低工廠的經(jīng)濟效益。另外提高電極鋼棒頭的焊接質(zhì)量，減小焊縫的壓降同樣具有節(jié)能降耗的重大意義。

PRS-200T鐵碳壓降測試儀可以直接測得電極組裝后的電阻及壓降，并在液晶屏上顯示出實驗電流、電阻、電壓降。該儀器測量準確、操作方便、性能穩(wěn)定，是一款針對性很強的儀器。用戶通過該儀器可以及時、方便的掌握電極組裝后的詳細數(shù)據(jù)，從而判斷組裝質(zhì)量的好壞，以便于及時修正組裝材料或者修改組裝工藝，加強組裝質(zhì)量的控制工作。

PRS-200T高精度鐵碳壓降測試儀可以直接檢測鐵碳模塊（陽極炭塊、陰極炭塊）及鋼棒頭焊接的組裝質(zhì)量，從而選用合格的鐵碳模塊可以為用戶節(jié)約了大量的電費。采用定制的測試線及測試夾具，讓測試更加方便、快速。減小了一線工人的工作量。

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.
