Abstract
An improved portable colorimeter is described in which there is a cap member detachably secured to a housing. The cap member can be placed in one position for enclosing the cell compartment for protection of the colorimeter during transport and storage. The cap can be placed in a second position over the cell compartment for preventing ambient light from entering the cell compartment during testing. In one embodiment the cap member rests in grooves adjacent the cell compartment during testing.
