The Smoke Opacimeter is capable of automatically measuring the opacity of smoke emitted by a diesel engine. It adopts advanced partial flow technology, allowing the measuring unit to directly test smoke emissions from diesel-powered vehicles. The "Scavenge air curtain" technology prevents optical system pollution. Constant temperature control in the sample cell avoids condensation and ensures accuracy, unaffected by temperature changes.

Features:

• Split structure with a separated measuring unit and control unit for easy operation;

• Large LCD screen featuring a Chinese or English interactive menu, providing opacity and light absorption coefficient readings for simple operation;

• Functions include free acceleration tests, measurement of transients, automatic processing of test data, and display of measuring results;

• Includes features for license plate number entry, saving, data storage, and viewing;

• 15 minutes warm-up time with automatic zero reset;

• Includes data printing and communication functions with the host computer through a serial RS-232C interface;

• Performance meets the requirements of ISO11614 and GB3847-1999.
