Portable Octane Number and Cetane Meter LOCT-A20 is a portable detector used for octane and cetane number measurement, based on theory of insulate magnetic permeability and electromagnetic induction. It offers 60 ×100 mm sensor and 15 hours operating time duration. The precise sensors can measure out parameters fluctuation of the tiny mediums, to get result of octane and cetane. The interface is use friendly with longer standby-cyclic charging battery. It has external cover with high strength, shock resistance and water, dust and moisture proof performance.
