Which parameter is NOT typically measured by the DR 900 multi-parameter colorimeter?

Explanation:
Colorimetric instruments like the DR 900 determine how much of a chemical is present by measuring the color produced when a reagent reacts with the sample. They’re designed to quantify substances such as chlorine residuals, fluoride, and, in some test kits, pH by reading the color intensity with a photometer. Temperature, however, is not a readout of this device. While reaction color can be influenced by temperature and the instrument may apply temperature compensation in its calculations, the DR 900 does not typically report a temperature measurement itself. To know the water’s temperature, you’d use a separate thermometer. So temperature is not a typical parameter measured by the DR 900.
