CA-2000
is an unique & highly-sophisticated
alcohol analyzer utilizing the
variation of electrical property
value of the oxide-semiconductor
when the alcohol substance is
detected. And, with the development
of new ceramic material combined
with relevant catalyst, it can
selectively analyze the alcohol
concentration to the ppm unit
existing in the human breath.
Our laboratory made it in developing
the highly-selective semi-conductive
sensor reactive to alcohol substance,
which can be differentiated
from the other semi-conductive
sensor products (which are often
affected by other substances
like smokes and smells of food).
Furthermore, it did improve
to the large extent the standby,
response & recovery time
which could be crucial
in measuring gas concentration.
-
Detection mechanism of our unique
semi-conductive sensor
When
the oxide having the property
of n-type conductivity is open
to the atmosphere, it decreases
the number of electron affecting
on electrical property by the
adsorbed oxygen and results
in increasing the resistance.
And, afterwards, if the specific
gas (reducing gas) exists in
the atmosphere, it reacts with
the adsorbed oxygen and increase
the electron in the oxide, resulting
in decreasing the resistance.
So to speak, the electrical
property of the oxide is getting
changed when a specific gas
is exposed from the outside
and our sensor can analyze the
gas concentration from the variation
of quantity.

| ¢Ê Features |
|
1)
Highly reliable accuracy by
the most sophisticated sensor
CA-2000
adopts a highly-selective
semiconductor sensor (reactive
to alcohol substance) designed
by KAIST(Korea Advanced
Institute of Science and
Technology ). CA-2000 is
an unique breath tester
adopting this most sophisticated
technology of sensor.
2)
Stable testing data
3)
Digital type ; It displays by
3 digits (0.xx% BAC/BRAC).
4)
Wide detection range : 0.00
- 0.40% BAC
5)
Long-term stability
6)
Compact & light weight hand-held
device
7)
Short warm-up & response
Time
After
power on, less than 20sec.
of warming up countdown
(200 to 000) is needed to
make it ready for testing.
And, exhaling just for a
few seconds will reach you
to instantly read the testing
numeric digits.
8)
Longer life time : 3,000 times
testing
9)
Quick Recovery Time
The
sensor of CA-2000 can be
purged in 30seconds for
another time of testing.
You don't need to
be too patient to do consecutive
testing.
10)

11)
Sanitary Testing
12)
Alarm Sound
If
you are out of legal limit
range, alarm sound will
be automatically beeping.
It could be customized depending
on the countries.
13)
Compact design and anaesthetic
outlook

|
| ¢Ê How
to Use |
|
1)
Turn on the PWR On/Off switch
Soon
after the power on, CA-2000
will start the countdown
200 to 000 on the display
window. - It is a "Warm-up"
process to make the sensor
and circuit be ready for
testing.
2)
When you hear beep sound &
green lighting is on READY,
please blow into for 3 seconds
till you would hear another
time of "Beep" sound.
N.B.
: 1.In this stage, if you
don't blow within 30 seconds,
it automatically shows OFF
display for turn-off
2.
In case you drink quite
a little (if actual concentration
would be below 0.01% BAC/0.05
mg/lBRAC), it may not be
activated. However, it shows
still 0.00% and you're said
to be in safe range.
3)
Then, the test result (BAC or
BRAC) will be displayed
by 3 digits for 15 seconds at
the same time both READY and
WARN lamps are flickering.
N.B.
: 1. If the BAC / BRAC data
would be over 0.05% / 0.25
mg/l(default setting) respectively,
red WARN lamp will
be flickering along with
"Alarm" sound.
2.
The "Alarm" level
is adjustable pursuant to
the local legal limit.
4)
Finally, it shows "OFF"
for turn-off.
5)
For the successive testing,
try again from No.1 to No. 3.

¢Ê To
get more accurate testing data |
- After
drinking, it is recommended
to test after 30 min.
It is because it takes
30 min. approximately
for alcohol to be absorbed
into blood from the
digestive organs. And
residual alcohol remaining
in the mouth may cause
inaccurate data.
- To avoid
testing under strong
wind or in the closed
room with contaminated
air.
- When
the "BAT LOW"
lamp is lighting on,
it's advisable to replace
9V alkaline battery.
- To attain
more accurate data,
please repeat testing
about 3 times.
