The flue gas ink to measure the telescope is for the environmental protection authorities and industrial and mining enterprises to environment pollution and save energy for prison special apparatus.
This instrument will smoke monitoring by pehr mann flue gas concentration diagram, measuring method transformation through high quality prism telescope distance measurement, therefore it has a small volume, view, ranging far, quick speed, high precision and easy to carry, easy to master many advantages, such as is a kind of monitoring smoke blackness of the ideal instrument.

Second, the main parameter

The telescope magnification 10 x

The telescope objective caliber 50

Pehr mann blackness level 0 level, level 1, level 2, 3 grade, grade 4, 5 levels

Visual observation error is not more than 0.5 level

Three, the structure and principle
The apparatus adopts binocular prism dishes system, and in telescope partition board system has a corresponding dry flue gas concentration pehr mann figure 1-5 levels of gray ladder piece, whole transparent part is for 0 level, through a telescope eyepiece observer left with the class will smoke target gray ladder block comparisons, thus determine blackness standards level.

Four, using method
From skin pocket instruments, degassing eyepiece cover and optical lens cover, then will be monitoring instruments aimed at the chimney mouth, telescope, make the chimney mouth dispel the black smoke clear, can compare determination.Determination should notice the following points:

Viewing of the sun's light (i.e. lighting direct light from the sky or the illuminate of light), and should be side light sight approximate at right angles, should avoid positive light and backlight

In Yin fog circumstance, because the sky background darker, should remember slightly low readings level

The chimney export background do not have hills, trees, and buildings like diablo obstacles

Observe shall represent the normal operation condition, request boiler boiler load keep in full load of 80%, and now is not to add water, not excessive coal balance drum wind release

The observations can not be a standard, can be mastered in the intervals between 0.1-1 minute, ordinal record data (each observation instantaneous blackness), such as smoke blackness in secondary between, estimated to 1 / level 2 blackness value, will ultimately measured values for the average, namely took soot black degrees

Five, maintenance

Instruments should be put in ventilated dry place, and stay away from the soda acid volatile Si or corrosive chemical

In use process, should prevent collisions, instrument appearance and the pattern of rubber also should avoid to contact organic solvents

Far telescope eyepiece objectives, such as interior parts are subject to inspection and to seal, don't arbitrary apart.Lens face such as dust dirt usable lens brush or lens paper dusted off

Every time with finish, beard mesh, optical lens cover respectively good cover, appearance, then wipe it off into the bag
