1、适用范围：测量用汽油、LPG、CNG及洒精作燃料的汽车发动机废气中碳氢化合物(HC)、一氧化碳(CO)、二氧化碳(CO2)、氧(O2)的含量和氮氧化物(NOx)的含量。也可给出过量空气系数λ的数值。
MainFeatures:
Used to measure vehicle emissions of HC, CO, CO2, O2 and NOx gas concentration, 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 where 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.
