Indicated error: co: f+5%(relative error: 0-10%) Co2: f+5%(relative error: 0-20%) Hc:f+5%(relative error: 0-4000ppm) f+10%(relative error: 4001-10000ppm) O2: f+5%(relative error: 0-25%) No: f+5%(relative error: 0-5000ppm) 6. Environmental condition: petrol temperature: f+2f¦(relative error) Engine speed: f+1.0%(relative error) Temperature: 0f¦-40f¦ Humidity: f_80% Atmospheric pressure: 60-105kpa Power: ac 220vf+10%, 50hzf+1hz 7. Preheat time: 10 minutes 8. Method of sample taking: Tail gas: taking directly, and the length of sample pipe and probe are 5m and 900mm Petrol temperature: put the probe into the hole of lubricating oil gauge of engine, and the length of probing is the length of oil gauge. Then seal it with stopper in order to avoid the leakage of oil. The pipe length is 5m Engine speed: the result is available at the point no more than 20cm from the high voltage coil of engine 9. Display method: lcd large screen display 10. Optional configuration: gas temperature and engine speed 11. Main features: built-in printer, and computer network communications, 30 minutes automatically suggest zero. Idle and idle-two measurement methods, plates imported functional group can store 500 measurements, natural gas, liquefied petroleum gas and petrol fuel three choices. Carton
