The YSI 9300 direct-reading photometer is an instrument that measures color intensity. Light is passed through a test tube containing the sample solution, and then through a coloured filter onto a photodetector. Filters have been chosen so that light of a specific wavelength is selected. When the solution is completely colourless, all of the light passes through the sample. With coloured samples, light is absorbed and that which passes through the sample is proportionately reduced.

In 9300 test procedures, the direct-reading photometer is used to measure the colour which is produced when chemical reagents are reacted with the sample. In these tests, the color intensity produced is proportional to the concentration of the parameter under test.

The photometer is pre-programmed with calibrations for each test parameter. Different test procedures are carried out at different wavelengths to optimise the sensitivity of each test. The required wavelength is selected automatically by the instrument.

The calibrations are accessed by entering a unique program number at the start of each test procedure. This enables the instrument to select the appropriate wavelength filter automatically and allows the photodiode response to be converted to a concentration reading. The instrument thus displays a direct-reading of the test result.

The photometer is ideally suited for general analytical applications. The instrument can be used as a laboratory or field photometer for standard analytical methods or for comparison of coloured solutions.

You can rely on the accuracy and reliability of YSI's 9300 photometer. Just choose the reagents for the parameters of interest and start getting results today.
