Srpski језик 1. Measure the opacity of motor vehicle exhaust using the principle of split flow measurement;
2. Compliant with Chinese national standard GB3847-2018 Limits and measurement methods for emissions from diesel vehicles under free acceleration and lugdown cycle;
3. Applicable for environmental authorities, test centers, auto manufacturers, workshops, etc.
☞ Adopting the "air curtain" protection technology to prevent the optical system from being contaminated by the exhaust. Constant temperature control in the measurement room to prevent condensation of moisture in the exhaust, which may affect the measurement results;
☞ Equipped with functions, e.g. real-time testing and free acceleration testing;
☞ Equipped with oil temperature testing function;
☞ Large LCD screen with clear fonts;
☞ User-friendly interface with graphical display;
☞ Equipped with RS485 interface for communication with external computers;
☞ Optional built-in micro printer;
☞ Optional speed analyzer to measure engine speed.
