MainFeatures:

Used to measure vehicle emissions of HC, CO, CO2 and O2 gas concentrations, automatic calculation shows that air-fuel ratio λ, can be the engine combustion performance and emissions of pollution in a comprehensive test. Use of advanced foreign technology, import the key components assembled. With a high-brightness digital display, automatic zero, linear automatic data processing, auto-alarm when the gas line blocking, fault diagnosis wher the unit automatically and print testing date, time functions, with built-in printer (or the analog output interface or RS -232A digital serial communication interface), can be freely idling and dual idling measure, with convenient operation, accurate measurement data, work stable and reliable characteristics.
