What does opacimeter mean?
measuring opacity
: an instrument (as a turbidimeter or a nephelometer) for measuring opacity.
What does an opacimeter do?
An instrument for measuring the opacity of a body or substance, especially by measuring the amount of light it reflects.
What is smoke meter?
Smoke meters, also referred to as opacity meters, detect and measure the amount of light blocked in smoke emitted by diesel engines from cars, trucks, ships, buses, motorcycles, locomotives and large stacks from industrial operations. US EPA has established Heavy Duty Diesel Test Standards.
What is an opacimeter and how does it work?
The basic principle of the opacimeter is measurement of attenuation of emitting light from the light source, which is transmitted through soot media and consequently absorbed. The measured results are then expressed as opacity (%) or in absorption coefficient in (m−1).
How is smoke measured?
Smoke measurements are made with a photometer system shining vertically through the tunnel near the exhaust end. The percentage of light absorbed by the smoke in the exhaust gases is recorded against time. The area under the curve obtained is taken as a measure of the total quantity of smoke produced.
What is smoke number?
Smoke number is the fractional reduction in reflectance by a smoke filter due to the blackening of its surface by soot. Extinction coefficient is the inverse of the path length over which light intensity decreases by the factor of e (2.718).
How is smoke formed?
Smoke occurs when there is incomplete combustion (not enough oxygen to burn the fuel completely). In complete combustion, everything is burned, producing just water and carbon dioxide. When incomplete combustion occurs, not everything is burned. Smoke is a collection of these tiny unburned particles.

Is smoke a solid or gas?
Gases are substances that are completely in a gaseous state at normal temperatures and pressures. Some liquids or solids have an associated gaseous phase which is called a vapour. Smoke is a fine solid formed by incomplete burning.
What is smoke use?
It is commonly an unwanted by-product of fires (including stoves, candles, internal combustion engines, oil lamps, and fireplaces), but may also be used for pest control (fumigation), communication (smoke signals), defensive and offensive capabilities in the military (smoke screen), cooking, or smoking (tobacco.
