Portable Digital Densitometer HUA-100
Instruction:
The HUA-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 HUA-100, with a
extremely wide light
range of between 650Cd/m and 320 000 Cd/m , 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.
Measurement:
1. Turn on HUA-100's power switch(1), then "--.--" appears which
indicate waiting for
Zeroing.
2. Place HUA-100 on a film viewer. We strongly suggest work with
LED film viewers,
such as HFV-2008, HFV-2009, HFV-2010 etc.
3. Keep the HUA-100 on the viewer, pressed down the Zero adj(2),
keep it down until
0.00 indication appears, then release the Zero adj(2).
4. Place the area of the specimen that you want to measure, then
put Measuring Spot(3)of HUA-100 on the area of the specimen.
5. Digital reading shows density of the specimen.
6. Short Press of Zero adj, the back light will turn on or off.
