Exhaust gas analyser

BMU 200

Exhaust gas analysis module with infrared technology, to link up to the pc thru serial port or optional bluetooth interface. Its small size and 12 v d.c power supply mean it can be used everywhere in a garage or at roadside inspections. Equipped with proprietary software EmissionPRO® MAHLE, for installation on PC, carries out various operations that help the operator to fine tune the vehicle’s anti-pollution devices:

Gas curve:

The unit automatically saves the gas readings at different engine speeds and plots them on a gas curve. Especially recommended for road tests or test bench tests.

Automatic diagnostics:

The program analyses the gas values and creates a list of individual readings.

Catalytic converter efficiency:

The program guides the user through the test and calculates the efficiency of the catalytic converter for the different types of gas in percent – ahead of and behind the catalytic converter.

Double lambda sensor test:

With its oscilloscope feature, the unit analyses variations in the signal and calculates an operating efficiency value.

Cylinder head leak test:

The program guides the user through the test and, by analysing the gases in the coolant expansion tank, is able to determine whether the cylinder head gasket is leaking.
