I. Introduction
Carbon monoxide (CO
2
) is one of the most common gases existing in daily life and
industry. Carbon Dioxide, colorless and odorless, is a natural component of air at
approximately 0.03 %. The HAL-HCO201 handheld carbon dioxide meter is a
compact personal monitor that can provide a rapid indication of CO
2
levels at the touch
of a button. The HAL-CO201, based on the most reliable and accurate dual-beam,
non-dispersive infrared (NDIR) sensing technology, features directly displays the
carbon dioxide concentration in ppm or percentage.
Low-power consumption design enables long operation time. Exceptional stability
and patented self-calibration algorithm allow very long intervals between calibration
intervals. The external digital temperature and humidity sensor or pressure sensor,
when applicable, allows compensation or correction for accurate measurement. The
USB port provides capability of downloading stored data and possible continuous,
real-time monitoring of the environment. The HalTech HCO201 Carbon Dioxide
meter makes it easy to take quick measurements of a wide range of CO
2
levels. With
a built-in pump, the HCO201 is a point-to sample instrument and responds very quickly
to ambient changes in CO
2
concentration.
The HAL-HCO201 Carbon Dioxide monitor can be widely used for continuous

epidemic prevention system, as well as air pollution and greenhouse testing.

2.1 Measuring Screen
The Measuring Screen is the main screen of the instrument for sampling testing. This
screen can be run at the default settings. It displays the test result and conditions
according to the unit settings. One may wish to change the settings before a
measurement run by pressing up or down arrow to enter into the Setup Screen. An
example of the Measuring Screen is shown in the Figure 1.

Figure 1 Measuring Screen
Battery Indicator
The battery indicator displays the battery strength graphically. Four bars represent
100% of charge in the battery; three bars 75%; two bars 50%; one bar 25%. No bars
signify a low battery status and simultaneously the alarm will buzz as a warning.
Charging of the battery is necessary at this level and after a few seconds of the warning
sound the instrument shuts itself off automatically.
Time and Date
The current date and time is always displayed in the format of year-month-day and hour:
minute: second, respectively. Date and time can be changed in the Setting screen.
Temperature & Relative Humidity (T and R/H)
Temperature and Relative Humidity automatically displays when an external
temperature and humidity sensor probe is attached.
• Use BACK keypad to toggle the concentration unit between ppm and
percentage if the sampling is not started.
• Push RUN/STOP keypad to start continuous measuring/sampling. During
the sampling process, the backlight will be off automatically.
• Data are logged or current sampling value will be saved every time when
the ENTER keypad is pressed. Push RUN/STOP keypad to stop measuring
and the backlight will be on again.

screen.
Figure 5 Setting Screen
Alarm level setting
The user may turn on or off the excess exposure limit warning. The user may input any
value at the increment of 1ppm between 0 and 5000ppm. For your reference, two
levels of limit for carbon monoxide are in common: 1) Threshold Limit Value (TLV) of
5,000 ppm (9,000 mg/m
3
) as a "ceiling limit" established by The National Institute for
Occupational Safety and Health (NIOSH) or American Conference of Governmental
Industrial Hygienists (ACGIH); 2) Permissible Exposure Limit (PEL) of 5,000 ppm
established by US Occupational Safety & Health Administration (OSHA). All of these
concentrations refer to exposures with durations of 8 hr/day, 40 hr/week for a working
lifetime and all are attempts to establish a "no effect" level. The Immediately Dangerous
to Life and Health (IDLH) limit is 40000ppm.
2.4 Calibration
After turning on the instrument, use up or down keypad to go to the Calibration Screen
(Figure 6). Users may calibrate the instrument at his/her own wish after using for a
certain time of period or suspect degradation of sensor performance.

Figure 6 Calibration Screen - 1
Recommended calibration method is the standard Zero-Span technique. The X
values in the first column represent the concentration of calibrating gas in ppm. The Y
values in the second column represent the response of the sensor to be calibrated. The
values in the third column are calibration coefficients. The default values of K and B are
1.00 and 0, respectively. Factory calibration was performed under the condition of
altitude at the sea level. One can set the altitude from 0 to 5000 feet to correct
variation of CO
2
concentration due to the altitude change. The example of calibration
procedures is described below:
Here we use a zero air and the vapor concentrations of 1000 ppm of carbon dioxide
standard gas cylinder as an example for calibration:
1) Enter into the calibration screen by pressing the ENTER keypad
2) Use up or down keypad to move the cursor to Altitude value if change is needed.
Set the altitude value at the proper height in feet. Press ENTER to confirm the
change.
3) Connect the inlet of the instrument to a glass container and then introduce the zero
air to the glass container
4) Enter into the calibration screen by pressing the ENTER keypad and make sure
that the left arrow pointed at the first row of 0ppm concentration (refer to Figure 7).

5) Press RUN/STOP keypad to start a sampling. Wait for right bottom number stable
and then press STOP key.
6) Connect the inlet to a glass container that is connected a standard CO
2
gas cylinder
(e.g., 1000ppm standard carbon dioxide gas cylinder).
7) Move the cursor to the second row (Refer to Figure 8) and then press the ENTER
keypad. Use or to select the element to be changed. When the
element of the X column becomes highlighted, use or to change the
number and press ENTER to confirm the change. Set the number as the
concentration level of the standard gas concentration to be tested (e.g., 1000ppm).
Then use BACK keypad to return to non-change screen with the cursor pointing at
the second row.

8) Press RUN/STOP keypad to sample, the correspondence value in the Y column will
display the response of the concentration for current liquid standard. Press
RUN/STOP keypad again to stop the sampling after the reading is stabilized.
9) After finished both samplings on standard gases, move the cursor back to the first
row, press and hold the ENTER key for about two seconds. The instruments will
automatically calculate and update the calibration coefficients based on new
calibrations. Press ENTER to save values.
10) After finishing calibration procedures, press BACK to exit.
• To restore the default settings of factory calibration, move cursor to highlight
RESET and then press ENTER to restore factory calibration for coefficients of K
and B. press BACK key to exit.
• One can always bypass the zero-air calibration if it is not necessary. In order
to do so, move the cursor back to the first row after taking the non-zero gas
calibration, press and hold the ENTER key for about two seconds. The
instruments will automatically calculate and update the calibration coefficients
based on new non-zero gas calibration (SPAN calibration) only. Press ENTER
to save values.
