Light brightness is measured with a device called a photometer. Direct reading photometers are often expensive and difficult to use. However, if we
only need to know when two light sources are...
The solution to be analyzed is discharged through atomizer to the chamber.The components get flamed and the light produced by the flame is absorbed through a optical sensor and causes change in the...
