Main technical features
1. Two methods(RON and MON)can be switched quickly. 4 sample tanks are configured.
2. It supports both interpolation and compression ratio measurement.
3. The software monitors all kinds of test parameters in real time clearly.
4. Equipped with a large capacity air conditioning unit DW30AU with two levels of temperature control, to supply dust-free, dry and constant temperature air.
5. It can save and print the test results. It supports LIMS network.

Original technologies
1. Signal transformer--Ensures the interconvertibility of the knock sensor.
2. Precision rotary encoder--No need to adjust the spark angle mechanically.
3. Ambient pressure compensation module--Automatic compensation.
4. DW30CU heat sink--For heat dissipation, no need to maintain daily.
5. ONManager® software--High integration, easy to use on the colored LCD.
