The IM-108 is a small high range survey meter employing an ionization chamber—it seems to have been the predecessor to the IM-174/PD

The IM-108/PD has two controls. One is an "OFF"—"SET" knob used to turn the instrument on and off and to zero the meter. The other control is a lever switch that is used to check the battery condition and to activate the zero adjust function. When the lever switch is held in the "Check" position, the instrument's sensitivity is increased and the rectangular label on the top of the unit (titled "Increased sensitivity meter correction.") indicates the exposure rates that apply. For example, when the lever is in the check position and the reading on the meter scale is 50 R/hr, the actual intensity is 5 R/hr.
