Detailed Product Description

SV-2LB-filter semiautomatic Smoke meter, which is produced 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-2LB, equipped with Nixie tube, is easy to operate by Prompt lamp and separately displays the lasted three test result and the average of them.

  Addition: The strong point of SV-2LB: Air compression is not needed while it works.
