Product Name: Intelligent High Frequency Switching Constant Potential Rectifier Trademark: YH Transport Package: Carton Packing Specification: high precision, energy saving Origin: China HS Code: 85043110 Product Description Intelligent high frequency switching constant potential rectifierProduct DescriptionIntelligent electronic instrument is convenient to carry and simple to operate, which can not only eliminate the influence of the IR drop generated by cathodic protection polarization current, but also can eliminate the influence of the IR drop generated by various stray current. It is convenient for field measurement, of which the measurement result can be obtained immediately. What's more, it can collect and preserve the metrical data and is convenient to export the supplying data for analysis and usage.Adopting the untreated chip technology and combining with power measurement technology and method, the intelligent potential measuring instrument can be used to measure the electrode potential value which will eliminate the IR drop of medium in theelectrochemical research work. If equipped with polarization measurement probe, it also can be used in accurate measurement of the cathodic protection potential in the on-sitecathodic protection project and the real-time collection and preservation of cathodic protection reference potential.Main featuresIt has the advantages of high precision, energy saving and high efficiency, high stability, convenient carrying and easy operation.Technology index3.1 Environmental Parameters a) Operating Temperature: -40ºC~+60ºC; b) Relative Humidity: 15%~90%RH; c) Atmospheric Pressure: 86kpa~106kpa3.2 Power Supply a) Li-ion3.6V battery; b) Battery capacity should ensure the continuous work of more than 8 hours.3.3 Potential Measuring Range: 0mv~±5000mv3.4 Potential measurement accuracy should be better than10mv3.5 DC Input impedance is not less than1MΩ3.6 Anti-interference Feature: the interference signal with50Hz, 30V is applied at the input end of the reference potential. The instrument can work normally, and the accuracy of the electric potential measurement should be better than 10mV.3.7 Drifting Feature: the instrument works for 24h continuously, and the accuracy of the electric potential measurement should be better than 10mV.3.8 Measurement and preservation of the potential of the energization and outage: the instrument can carry on the measurement of the potential of energization and outage, and can preserve the measuring potential of energization and outage as a set of data, which the number of the data sets are no less than 250.3.9, Data playback display of the potential of energization and outage: the instrument can make a playback display of the saved potential of energization and outage.3.10 Data collection and storage: the instrument can start and stop the reference potential of the data collection through the button, and store the collected data, of which the collecting rate is not less than 10 /s.3.11 Data export function: using the data exporting software can import the reference potential data (it is not the potential of energization and outage) that are collected and stored in the instrument into the computer, and the imported data can be saved as Excel file format.
