Exhaust emission measurements for the AU and more

With the mega compaa HG4, you perform the AU efficiently – and benefit from it even further. Because the quick and easy measurement of CO, HC, CO2 and O2 also helps you to reliably identify engine and combustion problems. Real added value for everyday work in the workshop!

The basic version of the mega compaa HG4 is suitable for exhaust emission measurements on petrol engines. It is completed by two additional devices to easily and efficiently measure diesel aggregates: the diesel opacimeter HG4-DMK (up to Euro 5/V) and the particle counter HG4-PCK, with which you can easily and efficiently carry out exhaust emission measurements on Euro 6/VI diesel vehicles.

With the mega compaa HG4 and its add-ons, you are absolutely on the right track and ideally positioned for performing AUs in the future.
