Diesel Exhaust Smoke meters, also referred to as opacity meters, detect and measure the amount of light blocked in a sample of smoke emitted by diesel engines from cars, trucks, ships, buses, motorcycles, locomotives and large stacks from industrial operations. The smoke meter readout displays the smoke density giving a measure of the efficiency of combustion. This makes the smoke meter an excellent diagnostic tool to ensure proper maintenance of diesel engines for improved fuel economy and protection of the environment.The opacity meter consists of an optical unit mounted inside a measuring head and a separate electronic control unit. The measurement principle is based on light extinction detection.
The collimated beam from the light-source (SLED) is absorbed and scattered by the particulate exhaust emissions. A photodiode determines the light intensity of the attenuated beam and the corresponding opacity value is transmitted to a separate remote display. Partial flow continuous gas sampling combined with a heated and temperature controlled smoke chamber compensates for changes in pressure and test conditions to give you the most accurate readings possible.
The Bridge Analyzer 4 gas analyzer measures Carbon Monoxide (CO), Carbon Dioxide (CO2), Fuel Dependent Hydro Carbons (HC), and Oxygen (O2). The analyzer comes in a hard case with all accessories as a complete, ready-to-use gas analyzer. Turn on the power switch, connect the hose and probe, push the Zero button. When the Zero is complete, the analyzer is ready to measure exhaust emissions gas.
Accessories include a stainless steel probe assembly, easy storing sample line, and a built-in water trap and particulate filters to protect the internal infrared optics of the analyzer.
