Abstract An intensity scale photographic sensitometer, type KS-2, at tong exposure time levels, has been designed and built. The possible exposure times by this sensitometer are 1/10-10 seconds on automatic operations. For exposure times, longer than 10 sec., a time switch has been prepared. The shutter is a focal plane type and made of two metal plates drived by a weight and control-led by electromagnetic mechanisms. As the time standard, a rotating wheete which is drived by a constant speed synchronous motor has been used. The size of test films is 48×120mm.
