Many years of operation experience has shown that in many cases, the acid value of the oil in operation is increased because of the hydrolysis of the oil, so the new oil standard is <.
600 mg/L.
The moisture standard of running oil is 1000 mg/L.
Moisture: Test according to GB/T 7600 method.
Moisture will not only lead to hydrolysis degradation of phosphate ester fuel oil, acid value increase, resulting in the corrosion of system components, but also affect the lubrication characteristics of the oil.
If the moisture content of the running phosphoric ester fuel exceeds the limit, the reason should be found out quickly and effective treatment measures should be taken.
SH103 micromoisture tester (produced by shandong shengtai instrument co., LTD.) adopts the principle of Karl fischer coulomb titration and microcomputer automatic control. Compared with similar products at home and abroad, it has the advantages of high sensitivity, fast electrolysis speed, short balance time, accurate blank deduction, accurate and reliable analysis results, etc.
It is a high quality analytical instrument for petroleum, chemical, electric power, environmental protection, medicine, scientific research and other departments.
The instrument uses 32-bit embedded microprocessor as the main control core, embedded mini-operating system;
The instrument comes with constant current detection, double circuit balance titration function;
The electrolytic tank adopts waterproof and sealed design;
