1、 Execution standards

HJ/T 398-2007 "Determination of Blackness of Flue Gas from Fixed Pollution Sources - Ringman Smoke Blackness Chart Method"

2、 Purpose:

XA-The 8001 Lingemann smoke blackness meter condenses the standard Lingemann smoke concentration map commonly used in various countries onto a piece of glass to monitor smoke blackness. By measuring the blackness of flue gas, the degree of air pollution caused by flue gas emissions and the utilization rate of fuel combustion can be analyzed, providing effective monitoring methods for environmental management and energy conservation.

3、 Technical indicators

1. Lingman blackness level 0-5.

2. View magnification of 10 times.

3. Observable distance ranges from 10 to 1000 meters.

4. The aperture of the objective lens is 80 millimeters.

5. Dividing the camera with a magnification of 2 times.

6. The error is not greater than 0.5 level.
