HPC501 Automobile exhaust gas analyzer is used to measure the concentration of HC, CO, CO2, O2 and NOx in the exhaust gas of automobiles, automatically calculate and display the air-fuel ratio λ, and can comprehensively detect engine combustion performance and emission pollution. Adopting foreign advanced technology and imported German movement. It has high-brightness digital display, automatic zero calibration, automatic data linearization processing, automatic alarm when the gas path is blocked, and automatic diagnosis of the unit when the fault occurs. The instrument is suitable for the detection of engine exhaust components of gasoline, LPG, CNG, alcohol and diesel fuel. , Optional built-in printer (or Bluetooth, RS232, analog interface), meet the new national standard GB18285-2018 and the US BAR-97 standard, meet ISO3930 or OIMLR99 class I accuracy, can perform free idle speed, double idle speed measurement and multi-condition measurement, It has the characteristics of convenient operation, accurate measurement data, stable and reliable work.
