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 Smoke on the left eyepiece to target and block the gray ladder compared to the standard level of determination of blackness.

The use of methods
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

Observations can not be a subject, each time interval can be controlled by between 0.1-1 minutes, followed by recording data (each observation instant blackness), as black smoke and dust in between the two can be estimated to 1 / 2 blackness 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
