SV-2LB-filter semiautomatic ***oke meter, which is produced according to the national standard GB/T11798.5-2001 and GB3847-83, can be used to detect the ***oke 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 h***e the test result of exhaust concentration by the black granule on the filter paper (unit: Rb ).
SV-2LB, equipped with Nixie tube, is easy to operate by “Prompt lamp” and separately displays the lasted three test result and the ***erage of them.
Addition: The strong point of SV-2LB: Air compression is not needed while it works.
