The WAGER Model 6500 Smoke Meter is in full compliance with the requirements of
the SAE J1667 test criteria—the current U.S. standard.
The software supplied with you unit(s) (V5.1 or above) allows the user to apply the
algorithm for ambient conditions (see SAE J1667 document, Appendix B) to convert saved opacity data.
The meter's simple design and portability makes it easy to obtain accurate
measurements. It provides an accurate means (± 1%) of detecting and measuring the
opacity of smoke emitted by a diesel engine.
The use of the Model 6500 Smoke Meter promotes combustion efficiency for fuel
economy and ensures compliance with diesel emission standards set by environmental
air quality codes.
