This equipment is used to ignite the engine exhaust measurement, measurement object for the discharge of exhaust HC, CO, CO2, O2, and NO concentration.The technical requirements of the specifications, features, and performance of the equipment meets the ISO3930OIML R99 and JJG688 related provisions, the detection accuracy level reached . Applicable to a simple transient conditions (Vmas) and steady-state conditions (ASM) system equipment for measurement of GB18285HJ/T289 condition equipment and technology required to meet the special analysis instruments.

MQW-511Suitable for spark ignition engine exhaust emissions of HC, CO, CO2, O2 and NO gas concentration measurement;

MQW-411Suitable for spark ignition engine exhaust emissions of HC, CO, CO2 and O2 gas concentration measurement.

 

  The device uses the non-dispersive infrared absorption principle (NDIR) the use of imported the HORIBA optical platform measuring CO, HC, CO2 concentration; using electrochemical sensors measuring O2, NO concentration.

 The device comes standard with speed, oil temperature interface engine speed and oil temperature can be measured.

 Standard RS232 interface to facilitate the detection line networking, data transfer and print statements.

 The sampling channel loading filtration system, efficient separation of oil and water in the exhaust gas and impurities from the sample gas sampling channels into line with the detection of high-precision sampling platform requirements, in order to ensure measurement accuracy and stability.

 Full Chinese menu operation, LCD liquid crystal large screen display.

 The device can automatically calculate and display the engine air-fuel ratio λ value, providing automatic zeroing, license plate number, input and time display function, provides smart search function of 500 measurement data storage and access to and license plate number.

 The motorcycle test mode.

 Optional external printer, directly print test data.
