SV-2LZ-- Full automatic Smoke meter, which is made according to the national standard GB/T11798.5-2001 and GB3847-83, can be used to detect the smoke level of diesel car ,the combustion analysis and the research of diesel engine. The instrument cramps out a definite store of exhaust from vent-pipe and get them through a certain area of filter paper. Then you can have the test result of exhaust concentration by the black granule on the filter paper (unit: Rb ). SV-2LZ, equipped with large liquid crystal display screen, is easy to operate by the function of menu prompt and separately displays the lasted three test result and the average of them.
Addition: The strong point of SV-2LZ: Air compression is not needed while it works and only 0.3MPa-0.4MPa compressed air is required when pipeline is being cleaned
