PWRW33400型柴油總污染物含量測定儀
本儀器按照GB/T33400測定中間餾分油，柴油及脂肪酸甲酯中總污染物含量的試驗(yàn)方法制造，適用于測定中間餾分油，柴油及脂肪酸甲酯中總污染物含量的試驗(yàn)。
方法概要
稱量一定量的試樣，在真空條件下用預(yù)先稱量的濾膜過濾，將有殘留物的濾膜洗滌，干燥并稱重。用濾膜的質(zhì)量差計(jì)算總污染物含量。
適用于20℃運(yùn)動黏度不大于8 mm2/s，或40℃運(yùn)動黏度不大于5 mm2/s的樣品的污染含量。粘度過大需要將已經(jīng)稱重的樣品用溶劑進(jìn)行稀釋。

PWRW33400 Diesel Total Pollutant Content Tester
This instrument is manufactured according to the test method for determining the total pollutant content in middle distillate oil, diesel oil and fatty acid methyl ester in GB / T33400, and is suitable for the test for determining the total pollutant content in middle distillate oil, diesel oil and fatty acid methyl ester.
Method summary
Weigh a certain amount of sample, filter with a pre-weighed filter membrane under vacuum, wash the filter membrane with residue, dry and weigh it. The quality of the filter membrane is used to calculate the total pollutant content.
It is suitable for the pollution content of samples with a kinematic viscosity of 20 ℃ not more than 8 mm2 / s, or a kinematic viscosity of 40 ℃ not more than 5 mm2 / s. If the viscosity is too high, the already weighed sample needs to be diluted with a solvent.
