this is stupid

Does anyone know what the box is called where you put the liquid that you want testing into? Thanks - it's called a cuvette

colorimeters do not select wavelength, merely a coloured slide that coveres a range of wavelengths, wave length selection is done on a spectrophotometer

how do u select a particular wave lenth in a colorimetr

apparently, the highest a reading can go on a colorimeter in the absorbance setting is 1.00, i.e. all the light is absorbed. however, during my experiments, i managed to smehow attain results of oer 1.00, e.g. 1.72, etc i have heard now, in contrast to what i initially thought, that colorimeters can go up to a reading of 2.00. i would be glad if someone could let me know what this reading shows, and if it is possible?

Sounds like you are talking about absorbance units.

[edit] Different types of devices all called colorimeter

This article mostly talks about the device that measures the absorbance of a solution, but those devices that measure the emittance of a display device (CRT, LCD, etc) or the reflectance of ink on paper are also called colorimeters. It does not give an equal treatment of these devices and is not clear about them at all. I think the introductory paragraph needs rewriting to make mention of all the kinds of colorimeters. ralmin (talk) 22:57, 10 December 2007 (UTC)

How about splitting into absorption colorimeter and tristimulus colorimeter and disambiguating colorimeter? --Adoniscik (talk) 22:05, 11 February 2008 (UTC)
