| Message: | Main Features
1. DSHB131 can measure both of gasoline’s octane value and diesel’s cetane value;
2. Rapid and precise measurement, user-friendly operation, larger screen with Chinese language, EL background light make it’s easier under dark environment, Chinese menu is also available;
3. Tree years quality guarantee for circuit board: we promise for free replacement within three years for any non-artificial quality problems. The sensors adopt full-sealed design with alloying metal. External cover has high strength, shock resistance and water/dust/moisture proof performance. As well as sponge inside.
4. Upper and lower limits pre-setting are available, the monitor will display when it’s over the limit, which is convenient for the users.
5. Auto-off function can save energy and realize low power consumption. There are 4 reliable batteries for recycling charging.
C:Measurement Theory
The theory of octane and cetane detector is based on the measurement of insulate-magnetic permeability and feature of electro-magnetic induction. By detecting the dielectric medium of oil and comparing with the data model, the detector can measure out the value of octane and cetane. The precise sensors can measure out parameters fluctuation of the tiny mediums, then get the result of octane and cetane.
