Portable Digital

Densitometer DT-100



Handy portable type densitometer

High Accuracy +/-0.03 D

No warm-up time

Program Mode for custom calibration

Extremely wide light range of between 650 Cd/ m2 and 320,000 Cd/ m2

Light illuminated 4 digit LCD display with low battery indicator

Long life due to its low power consumption

Rugged design, whole alloy aluminium


The DT-100 is a robust, easy to use, portable densitometer for measuring the transmission

density of x-ray film. The unit has been designed for using in one-site mobile darkrooms,

laboratories and offices.


The DT-100, with a extremely wide light range of between 650 Cd/ m2 and 320,000 Cd/ m2,

has a density measuring range from 0D to 4.5D with an accuracy to within 0.03D over an

aperture of 3mm in diameter.


The operator simply places the film on the viewer (emulsion side up), places the probe on 

the film where the reading is required and the reading will appear on the 4 digit LCD screen

with white light illuminated display. And a low battery warning indicator is provided on the

digital display.


DT-100 comes complete with its own battery in a handy sturdy portable smart bag, ready

to use straight away.


Technical Specifications:



650 Cd/ m2 - 320,000 Cd/ m2

(5,000Lux – 1,000,000Lux)




0.00 – 4.50 D*


* We strongly suggest DT-100 work with FV series LED viewers.


With FV-200S, the maximum density of DT-100 would be >5.00D.
