With Separate Probe For Measuring The Transmission Density Of X-ray Film Portable Densitometer
Separate probe Densitometer
The HUA-200 is a robust, easy to use, portable densitometer with separate probe 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 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.

Notice: Make sure AA battery have been placed into battery compartment in the right polarity.
Measurement:
1. Long press the power switch (1) for more than 1 second until “-.--“ appears which indicate waiting for Zeroing.
2. Place the probe of HUA-200 on a film viewer.
3. Keep the probe 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 probe of HUA-200 on the area of the specimen.
5. Digital reading shows density of the specimen.
6. Short Press of power switch(1), the back light will turn on or off.
Maintenance:
When “LO BAT” sign appears, replace battery. Be careful to insert them in the correct polarity.
Program Mode: (carefully use it if it is really needed)
1. Turn off the HUA-200.
2. Keep Zero adj(2) pressed down, then long press power switch(1), until “+000”
appears, then release the Zero adj(2) and power switch. It means you have entered
into Program Mode.
3. Short press the Zero adj(2), it will turn between “F0-F1-F2-F3-F0”.
a) F-0: Original data, no Curve Matching.
b) F-1: Black and white film base (lithographic film)
c) F-2: Blue film base(Industrial film)- Default option
d) F-3: Domestic film
4. After the Program, you need to reboot the unit.
Notes: Each HUA-200 is strictly calibrated during factory, and initial factor should be 0.00. If the margin of error exceed ±0.03. First make sure your specimen is valid and trustable, and then you can enter into Program Mode to recalibrate it.
