Handheld Black-White Densimeter Digital Densitometer With Density
Tablet HUA-910
HUA-910 digital black and white transmission densitometer is been
used to measure the light quantity which through the transparent
material(like film base). It has lighting system, acquisition,
measure system and signal processing system. Densitometer use AC
modulation light source to offer stable light.
HUA-910 Summary
1. HUA-910 digital black and white transmission densitometer, equip
advanced detection sensors. It is a kind of high precision
instrument which been tested for thousand times. Small size, light
weight, easy to operation and carry, high precision and stable.
2. HUA-910 digital black and white transmission densitometer, can
measure the density value and density difference. It use computer
to control and process data, therefore HUA-910 has good light and
electrical resistance. Nonlinear fitting technique can rise the
precision. Add LED location aura to help customer locate measure
point. Use metal shell to shield EMI jam.
3. HUA-910 digital black and white transmission densitometer has
been tested before it deliver to customer. Customer can operate it
immediately. Standard density slice can do calibration.
4. HUA-910 digital black and white transmission densitometer can
measure the transmission density which below 5.0D. It is a good
instrument for analysis the quality of X-ray film of pressure
vessel, hull, chemical industry, bridge, hospital.
How to use
1. Turn on the power supply of the densitometer, turn on the power
switch, and the display displays "---", indicating that the
instrument is normal. The measurement can be carried out only after
preheating for 2 minutes.
2. Zero calibration, that is, without placing any sample, press the
measuring arm and press the zero calibration button at the same
time. After the display shows "0.00", release the measuring arm and
the instrument enters the state to be measured.
3. At this time, as long as the tested sample is placed in the
measuring area, aligned with the light hole and pressed down the
measuring arm, the reading of the display is the density value of
the tested sample.
4. Loosen the probe arm and the displayed value remains unchanged.
5. Density difference measurement: measure the reference sample
after zero calibration, loosen the measuring arm after the reading
is stable, and then press the zero calibration button to display
"0.00"; Then place the sample to be compared in the measuring area
and press the measuring arm. At this time, the density difference
between the two samples is displayed.
6. Without any sample, the instrument can enter the normal density
measurement state after zero point calibration.
Matter need attention
1. During zero calibration, no shelter shall be placed under the
probe arm. If there is any shelter, the actual density value of the
measured negative film is inaccurate.
2. The probe and measuring hole shall be kept clean so as not to
affect the accuracy of the probe.
3. The instrument shall avoid strong vibration, strong magnetic
field interference and strong light irradiation.
4. As the calibration standard, the standard density film should be
kept well to prevent mildew, aging, pollution or scratch, and avoid
strong light exposure. The user only needs to enable this
densitometer if he has doubts about the instrument reading.
5. HUA-910 portable black-and-white transmission densitometer is a
high-precision instrument. Attention should be paid to dust-proof,
moisture-proof, acid and alkali proof substances during use and
storage. After the instrument is out of use, cut off the external
power supply, place it in a cool, dry and ventilated place, cover
the light hole and probe, and avoid strong mechanical vibration and
corrosive gas.
6. When the displayed value reading exceeds the specified density
range, the measured value still has reference value.
7. The instrument is delivered from the factory and has been
accurately calibrated. Please do not disassemble it at will.
