Cosber Exhaust Opacity Meter

KYD-6 Opacity Meter:

KYD-6 Opacity MeterSmoke 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 and locomotives 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.

Main characteristic :

  • Split structure, separated measuring unit and control unit for easy operation.
  • Large LCD screen, Chinese or English interactive menu, with opacity reading and light absorption coefficient reading, simple,
  • Direct and convenient operation.
  • With functions of free acceleration test and measurement of transients, automatic process of test data and display of measuring results
  • With functions of License Plate Number entry, save, data view.
  • 15 minutes warm-up time, automatic zero reset.
  • With adoption of advanced partial flow technology, measuring unit tests smoke emissions of diesel-powered vehicles directly. “
  • Scavenge air curtain” technology prevents the optical system from being polluted. With constant temperature control in the sample cell, it can avoid condensation and influence of accuracy due to change of temperature.
  • With functions of data printing and communication with host computer. Serial RS-232C interface or RS-485C interface can be selected.
  • The performance meets the requirements of ISO11614 and GB3847-1999.
