Main Features:

Used to measure vehicle emissions of HC, CO, NOx gas concentration, using 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 Bluetooth / RS232A interface), can be freely idling and dual idling measure, with easy

operation, accurate measurement data, work stable and reliable characteristics.
