1. The non-dispersive infrared method is used to measure CO, HC and CO2 in motor vehicle exhaust, and the electrochemical principle is used to measure O2 and NO. The excess air coefficient λ is calculated according to the measured CO, CO2, HC and O2 values; 2. The instrument is small in size, easy to operate, accurate in measurement and reliable in work. It is suitable for automobile factories, motorcycle repair shops, etc.
☆ instrument platform a full set of imported components, small size, easy to operate, accurate and reliable measurement; ☆ with automatic zero calibration function, high degree of automation;
☆ Instrument interface image design, menu type operation, more convenient to use;
☆ Multi-stage filtration system design can avoid the pollution of the sensor caused by long-term use;
☆ Communication with PC through RS-232 serial port;
☆ The exhaust emission detection process can be carried out on a single machine under idle speed and double idle speed processes;
☆ Optional external or built-in micro printer, with direct printing function; In line with the international standard ISO 3930 or OIML R99 class I accuracy requirements.
