Ringelmann black Meter

First, use Determination of the smoke telescope Mexican environmental authorities and industrial and mining enterprises for environmental pollution and energy conservation to monitor special equipment.

This instrument will monitor smoke on the Ringelmann smoke concentration measurement method graph prism into the telescope through high-quality long-distance determination, it is small, a large field of view, ranging far, fast, high precision and easy to carry, easy to master and a series of advantages, is an ideal of black smoke and dust monitoring equipment.

Second, the main parameters 10 × magnification telescope 50mm objective lens diameter telescope Ringelmann black grade 0, 1, 2, 3, 4, 5 Visual observation error is not greater than 0.5 Third, the structure principle The instrument uses the prism binocular telescope system, and in the telescope on-board system, a corresponding partition of dry Ringelmann smoke concentration level grayscale steps in Figure 1-5 blocks, the transparent part is 0, the observer through the telescope objective lens to the left with the gray dust ladder block comparison to determine the standard level of blackness.

Remove the instrument from the bottle, degassed eyepiece cover and lens cap, and then align the instrument is monitoring the chimney, adjust the telescope so that the chimney emitting smoke clear determination can be compared.

Should note the following determination: Observed when the illumination (ie, sun's direct light or light from the sky light) should be the side edge, and the approximate right angles to the line of sight to avoid a positive light and backlight In overcast fog case, because the sky background is dark, slightly lower reading level should be remembered Do not exit the chimney background mountains, trees and buildings, obstacles like Diablo Observe the normal operation of the boiler should be representative of the state, the load required to maintain the boiler in the rated load of 80% or more, this time not to add water, coal, shall not be excessive blast Dilute value, and finally averaging the measured values, that is, the blackness of the smoke V.

Maintenance Instruments should be placed on dry air, and stay away from acid and other volatile or corrosive chemicals trunk In use, should be to prevent the collision, appearance and pattern of rubber equipment should also avoid exposure to organic solvents Far from the telescope objective lens, eyepiece and other internal parts are inspected and sealed, not any apart.

Dust and dirt can be used if the mirror lens brush or lens paper wiped Completion of each use, shall present, lens cap cover, respectively, appearance wipe clean, then put the bag Six complete sets of equipment 10 × 50 binoculars for determination of black smoke 1 set Manual 1 1 bag of desiccant Leather 1 Belt 1 Quality certificate 1
