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.The main technicalparameters:1Measurement scope 0-10 Rb 2accuracyNot exceed  FS ±33Repeatability: Not exceed FS ±2 4StabilityNot exceed FS ±2/h5Resolution 0.1 Rb 6Environmental condition temperature0~40 Relative humidity20-80 Air pressure70~105kPa power AC 220V±10%50Hz7Preheat time 5min8Sampling system swept volume330ml±15ml swept actuation time1.4S±0.2S tightness of extracting pump The air infiltration capacity is not exceed 15ml in one minute.filter specificationwidth:40mm,thickness0.18mm,Equivalent pore diameter: 45um, air permeability :3000ml/cm2.min, brightness: 85Sampling tube: cylinder: 5mm, length:  5m.
