<P>PROBLEM TO BE SOLVED: To provide a fuel property measurement device capable of measuring properties of a fuel with accuracy under consideration of temperature characteristics of optical properties of the fuel. <P>SOLUTION: A housing 7 of the fuel property measurement device is provided with a detection part 1 for containing fuel whose property is to be measured, a light-emitting element 2, a detecting light-receiving element 3 which receives the light transmitted through the fuel and an auxiliary light-receiving element 4. Based on the output of the auxiliary light-receiving element 4, the temperature of the light-emitting element 2 and the temperature of the fuel are specified. An arithmetic unit 6 stores a function (approximation formula) for measuring the property of the fuel in the detection part 1 based on the relationship between the light emitting amount of the light-emitting element, the light amount of the transmitted light, the temperature of the fuel and the property of the fuel. <P>COPYRIGHT: (C)2012,JPO&INPIT |
