Air/fuel ratio counter and RPM data recorder KOSO with BOSCH® LSU 4.9 sensor

Air/fuel ratio indicator and RPM data recorder with BOSCH® LSU 4.9" sensor. The Koso DL-03A with BOSCH® LSU 4.9 sensor shows the air/fuel ratio, has a RPM data recorder, and can optimize driving performance thanks to the associated reading capacity. A tachymeter, a digital voltmeter and 5 different lights are also integrated. A special feature of the DL-03A is the heating screen, which optimizes the visibility of the displays in cold weather. Large digits and light background lighting also facilitate reading. The meter is easy to use, compact, lightweight and can be mounted on many vehicles such as snowmobiles and UTVs.
