Main Features:

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, linearautomatic

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 Bluetooth / RS232 interface), can be freely idling and dual idling measure,

Multi-mode measurement，with convenient operation, accurate measurement data, work stable

and reliable characteristics.
