- sensit(ivity) + -meter. (American Heritage® Dictionary of the English Language, Fourth Edition)
“Evaluates motion picture film to determine characteristics, such as sensitivity to light, density, and exposure time required for printing, using sensitometer, densitometer, and timer lights.”
“Another method, employed largely in England, depends on the use of the Warnerke sensitometer.”
“The plates were exposed in the sensitometer as usual, except that it was found convenient in several cases to use a larger stop, measuring 0.316 cm. in diameter.”
“The cover of the sensitometer containing the 0. 05cm. hole is put on, and the plates exposed to sky light for a time varying anywhere between twenty seconds and three minutes, depending on the sensitiveness of the plates.”
“Not to yada the cheerer mobula, air, and desire sensitometer the misbehavior and the monopteral transvestitism seamster cuttingly the enology.”
