What is the difference between a colorimeter and a spectroradiometer?

In water quality testing, colorimeters and spectrophotometers analyze water samples by transmitting light beams of specific wavelengths through the liquid. Colorimeters operate as tristimulus instruments, using three color filters (red, green, blue) that replicate how the human eye detects color changes in treated water samples. Spectrophotometers function as spectral devices, measuring light absorption across multiple wavelengths to quantify contaminant concentrations in water.
