Scope Kerosene smoke point tester is based on the standard gb / t382-83 (91) "determination of the smoke point of kerosene" design and manufacture. The maximum height for the determination of the lamp with kerosene and jet fuel smoke point, that the sample in a standard fixture, smokeless flame under specified conditions of, expressed in millimeters. Features 1, kerosene smoke point tester uses millimeter scale background, you can clearly read the data 2, the entire instrument is compact structure, complete 3, kerosene smoke point tester using plug-type structure, more convenient to replace the wick 4, kerosene smoke point tester using a special glass observation window, easy to operate 5, kerosene smoke point tester simple operation, high measurement repeatability Technical parameters 1, the scale: ruler should on the black glass with white flags, their white or black stripes central 2 mm will be divided into bisecting vertical ruler. Ruler measuring range should be 50 mm, 1 mm division. Every 10 mm on the digital standard, with each 5 mm long marking. 2, wick catheter: top wick catheter should be exactly at the same level with the zero on the scale. 3, the lift base: total distance of not less than 10 mm stroke, moves smoothly and evenly. 4, ? reservoir oil: oil reservoir mainly by oil storage body, wick pipes and air ducts, etc., whose critical dimensions conform to gb / t382, oil storage body diameter size ?21.25 ± 0.05, length of 109.0 ± 0.05; wick tube diameter ?4.7 ± 0.05, length of 82.0 ± 0.05; air duct diameter size ?3.5 ± 0.05, length of 90.0 ± 0.05.
