NHT-6 Diesel Exhaust Emission Gas Analyzer

Features:

NHT6 Opacimeter is a portable intellectual instrument used to test the visible contaminants in emissions (exhaust smoke) from the compression combustion diesel engine. With advanced test technology and excellent parts and components from abroad, it is applicable for environmental protection departments, vhicle test staations, automotive manufactures and workshops.

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. With functions of License Plate Number entry, save, data view.

5. 15 minutes warm-up time, automatic zero reset.

6. With adoption of advanced partial flow technology, measuring unit tests smoke emissions of dieselpowered 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.

7. Equipped with oil temperature measurement probe.

8. Equipped with RS-232C digital serial interface for communication with external computer.

9. The performance meets the requirements of ISO11614 and GB3847-2005.
