What is the moisture content stipulated in the new fuel oil standard?

Moisture: Years of experience with resistant fuels have shown that in many cases the acid value of the oil in operation is increased due to the hydrolysis of the oil, so the new oil standard is & LT;
600 mg/L.
The moisture standard of the operating oil is 1000 mg/L.
Moisture content: test according to GB/T 7600 method.
Water will not only lead to the hydrolytic degradation of phosphate ester resistant fuel, increase of acid value, cause the corrosion of system components, but also affect the lubrication characteristics of the oil.
If the water content of the phosphate anti-fuel exceeds the standard, the cause should be identified quickly and effective treatment measures should be taken.
SH103 trace moisture tester (produced by Shandong Shengtai Instrument Co., LTD.) adopts The principle of Karl F. Coulomb titration and adopts microcomputer automatic control. Compared with similar products at home and abroad, SH103 trace moisture tester has the advantages of high sensitivity, fast electrolysis speed, short balance time, accurate deduction of blank, accurate and reliable analysis results, etc.
It is a high quality analytical instrument for petroleum, chemical industry, electric power, environmental protection, medicine, scientific research and other departments.
The instrument adopts 32-bit embedded microprocessor as the main control core and is embedded in the mini-operating system.
The instrument has constant current detection, double circuit balance titration function;
The electrolytic cell adopts waterproof sealing design;
Support multiple calculation formulas, in line with the standard GBT11133 and ASTMD 0304.
Technical parameters:
Carl, -- Hugh coulomb's law, to determination of trace moisture of different materials, in line with the GB/T11133, this trace moisture meter and the success of the application of this method, and used the micro computer control, its fast analysis speed, high precision, Chinese LCD color screen display, automatic printing, double CPU design, blank current deducted automatically and instrument fault self-diagnosis function, menu selection, and other functions, to achieve a better operation and use, has simple operation, automatic analysis instrument.
