For sale: Photronix Delta III transmission densitometer. $35.00 Excellent condition, fully functional with original instructions and power supply. Very compact and easy to store; 9.5" long, 7" wide, 6.5" tall. This densitometer was made in the sometime in the early 90's. This is a transmission (film only) densitometer. It does work well and the readings are consistent, yet measurements of a step wedge are off and there are no user calibration instructions. The original calibration has likely drifted with age.
