Product Description

Main Function 1.Split structure, separated measuring unit and control unit for easy operation. 2.Large LCD screen, Chinese or English interactive menu, with opacity reading and light absorption coefficient reading, simple direct and convenient operation. 3.With functions of free acceleration test and measurement of transients, automatic process of test data and display of measuring results. 4.*0 minutes warm-up time, automatic zero reset. 5.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 micro printer and RS***2C Serial interface to communicate with external computer. ***** performance meets the requirements of ISO****4 and GB********5.
