Laoyinghaina LY-NDVIS gas instrument

LY-NDVIS transmission smoke meter module is a split-flow high-performance smoke meter module independently developed by It can meet the technical requirements of JJF 1482-2014,JJG976-2010 and other standards,and has opacity N,absorption coefficient K and There are three readings of the standard optical channel effective length absorption ratio Ns,and it supports N value calibration,smoke temperature calibration and other functions.

The module works based on the physical principle of light attenuation. A beam of light is obscured by particles in the exhaust gas. The intensity of the beam is related to the concentration of particulate matter. The relationship can be expressed by the Beer-Lambert law. Opacity N is also called the absorption ratio,which represents the ratio of the absorbed light flux to the incident light flux when the light emitted from the light source passes through a dark channel filled with smoke.

The transmission smoke meter developed by integrating this module can be used to measure visible pollutants emitted by compression ignition engines or cars equipped with compression ignition engines; it is widely used in motor vehicle testing stations,automobile manufacturers,and automobile repair shops.,environmental protection agencies and other places.

The opacity parameters are accurately measured,the performance is reliable and stable,and it meets the national standard requirements. It has a built-in accurate and reliable temperature control system that can work under different environmental conditions. It has low maximum power and average power,small size,light weight,simple interface,and high integration. sexual characteristics.
