Robust And Easy To Use Handy Digital Densitometer
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.
Technical Specifications:
Range: | 650Cd/m - 320 000 Cd/m |
Density: | 4.50D - 5.00D |
We strongly suggest HUA-100 work with HFV series LED viewers. With HFV-2008, the maximum density of HUA-100 would be > 5.00D. | |

Program Mode
1. Enter into Program Mode:
Keep Zero button pressed down, then turn on power switch(1), until 8 arrows appears, then release the Zero button. It means you have entered into Program Mode.
2. F-x function
After entered into Program Mode, you will see F- x(x=0,1,2 or 3).
F0: original data, suit to our local market.
F1: suit to China market
F2: suit to U.S market (default)
F3: Null
Short press the Zero button, factor x will be turn between 0-1-2-3-0.
Note: the factor will save automatically
3. Advanced calibration function
In the F-x interface, long press Zero button, after display A.0B(A,B=0,1,2 …or 9), release Zero button.
Short press the Zero button, factor B will turn between 0,1,2,3,…9,-9,-8,-7…-1,0.
Long press the Zero button, factor A will turn between 0,1,2,3,…9,0, and save the previous factor B.
In previous version, we can only set 1 factor (from -0.05 to +0.05),this factor will be valid from 0.00-5.00 H/D.
Now, we can set 20 factors (from -0.19 to +0.19), each factor be only valid for corresponding density range, see the table below:
With the help of this function, we can just calibrate several certain density ranges,
for example:
So we can set corresponding factor as below:
After that, you will get the right measurement. for most of case, you don’t need to calibrate,because we already have F0-F1-F2-F3 mode.
