Hc10 Ringman Smoke Telescope/Detailed Information on Measuring Smoke Blackness:

Purpose:This smoke opacity measuring telescope is a specialized instrument used by environmental protection departments and industrial and mining enterprises to monitor environmental pollution and energy conservation. This instrument converts the monitoring of smoke and dust from the Ringman smoke concentration map daily measurement method to remote measurement through high-quality prism telescopes. Therefore, it has the advantages of small size, large field of view, long distance measurement, fast speed, high accuracy, easy portability, and easy mastery. It is an ideal instrument for monitoring the blackness of smoke and dust.

Main parametersTelescope magnification10×Telescope objective aperture50mmRingman Blackness Level0、1、2、3、4、5Grade; Visual observation error ≤0.5level

structural principleThis instrument adopts a binocular prism telescope system, and a corresponding dry Ringman smoke concentration map is made on the telescope reticle1-5A grayscale staircase block with a fully transparent section0level,The observer compares the smoke target with the grayscale step block of that level through the left eyepiece of the telescope, in order to determine the standard level of smoke blackness.

Instructions for useTake out the instrument from the leather bag, remove the eyepiece cover and objective cover, then align the instrument with the monitored chimney mouth, adjust the telescope to make the black smoke emitted from the chimney mouth clear, and then compare and measure. When measuring, attention should be paid to:1）The illumination light during observation (direct sunlight or sky illumination) should be side light, approximately at a right angle to the line of sight, and avoid front light and backlight.2）In cloudy conditions, due to the dark background of the sky, readings should be taken at a slightly lower level.3）There should be no dark obstacles such as mountains, trees, or buildings on the background of the chimney exit.4）When observing, it should represent the normal operation status of the boiler and require the boiler load to be maintained at the rated load80%Above, water should not be added to the coal at this time, and excessive air should not be blown to balance the release.5）Observation cannot be based on one time, the interval between each observation can be0.1-1Within minutes, record data in sequence, such as smoke and dust opacity between level two, which can be estimated0.5The level of blackness value will be measured and the average value will be taken, which is the blackness of the smoke and dust

maintenance：1）The instrument should be placed in a ventilated and dry place, away from volatile or corrosive chemicals such as acids and bases.2）Prevent collision during use, and avoid contact with organic solvents on the surface and patterned rubber of the instrument.3）The internal components such as the telescope objective and eyepiece have been inspected and sealed, and should not be opened arbitrarily. If there is dust or dirt on the mirror surface, it can be wiped off with a lens brush or lens paper.4）After use, cover the eyes and objective lens, wipe the surface clean, and put it into a bag.
