Optical Densitometers

Trans-4V : Optical Densitometer with Built-In Light Source

Trans-4V is a battery operated hand-held black and white transmission densitometer with a build0in light source. Both Trans-4V and Trans-4(E) have achieved the accuracy and stability, not so far offered in portable / field densitometers. The instrument size and shape makes it an ideal portable instrument for use in laboratory, plant or in the field.
