Features 1.NHT-6; take the style (split) measurement method. The "air curtain" protection technology is used to protect the optical system from smoke pollution. The measuring chamber is thermostatically controlled to prevent condensation in the exhaust gas and affect the measurement results. 2. Full Chinese interactive menu prompts. It displays two indications of opacity and light absorption coefficient, which is simple, intuitive and convenient. 3. The control unit is separated from the measuring unit to avoid smoke from contaminating the display and facilitating reading during testing. 4. According to the provisions of GB3847-2005 Compression-ignition engine and the installation of compression-ignition engine visible pollutant limit and test methods for vehicles, the free acceleration test of the vehicle and the new production vehicle. The test program is programmed to automatically process the measurement data and show the peak value of each test. And automatically judge whether the test conditions meet the relevant provisions of the national standards, and complete the complicated test steps in the shortest time. 5. Has the function of real-time test and display instantaneous value. It can measure the visible pollutants in the exhaust gas under steady-state conditions. 6. With engine speed test function, it can be configured with three measurement methods: piezoelectric, photoelectric and battery. The conventional configuration of this instrument is piezoelectric, and the other required devices can be purchased by the user. 7. With engine oil temperature test function. 8. Large screen LCD display, you can adjust the display brightness at will. 9. Equipped with a serial RS232 interface to communicate with external computers. 10. With clock date function and license plate number input function. 11. More than 500 sets of free acceleration test data can be saved and transmitted to an external computer through the serial RS232 interface, suitable for road inspection. Technical Parameters 1.
