1Description
SGTP-CO is a portable single gas detector designed to detect the presence of CO gas in the ambient
environment. SGTP-CO has a replaceable gas sensor and battery, giving an unlimited lifetime of operation.
When activated, SGTP-CO continuously monitors ambient air for the presence of carbon monoxide (CO)
and alerts the user to potentially unsafe exposure with LED, vibrating, and audible alarms in the event that
gas concentration exceeds alarm set points.
The SGTP-CO is designed for use in hazardous areas and offers reliable and durable monitoring in a
compact, lightweight package. It is also designed to withstand the harshest industrial working conditions
and is simple to operate.
2Warning
Any unauthorized attempt to repair or modify the product, or any other cause of damage beyond the
range of the intended use, including damage by fire, lightening, or other hazard, voids liability of the
manufacturer
Activate this product only if sensor, visual, detection, and audible cover are clear from contaminants
such as dirt and debris that could block the area where gas is to be detected.
Do not clean and rub the LCD screen of the products with a dry cloth or hands in hazardous
environment to prevent the static electricity.
Perform cleaning and maintenance of the products in fresh air that is free of hazardous gases.
Test the response of a sensor regularly by the gas concentration exceeding alarm set point
Test LED, audio and vibration manually.
Gas concentration measurements by the sensor can vary based on the environment (temperature,
pressure and humidity). Therefore, calibration of SGT-P should be performed in the same (or similar)
environment of the device’s actual use.
If the temperature changes sharply during use of the device (e.g., indoors vs outdoors), the value
of the measured gas concentration can suddenly change. Please use the SGT-CO after the gas
concentration value has stabilized.
Severe vibration or shock to the device may cause a sudden reading change. Please use SGT
CO after the value of gas concentration has stabilized. Excessive shock to SGT-P can cause
the device and/or sensor to malfunction
All alarm value is set based on the alarm standard that is required by international standard. Therefore,
alarm values should be changed only under the responsibility and approval of the administration of the
work site where the instrument is used.
Use IR communications in the safety zone which is free of hazardous gases.
Replace the battery and sensor in clean environment, which is free of hazardous gas.

3Caution
Before operating this device, please read the manual carefully.
This device is not a measurement device, but a gas detector.
If calibration and self-test fails continuously, please do not use the device.
Before use, please check the activation date, and if the activation date is past, please do not
use the device.
Clean detectors with a soft cloth and do not use chemical substances for cleaning.
To maintain 24 months lifetime, avoid the below activities except the necessary cases to check
events (Max/Min), lifetime/concentration, and alarm set points. Otherwise, the frequent use of the
button will deplete the battery lifetime less than 24 months.
View a serial number on the label at the back side of the device.

5Activation & deactivation
In a safe environment, when pressing and holding the button for 3 seconds, gas type and
firmware version (ex. v2.2) will be displayed. For 10 seconds countdown, the device will be
stabilized. After stabilization is completed, “V” icon will appear on the display screen and the
device will move to Measuring.
In the event that stabilization of the device fails, will appear on the display
and Measuring mode will not be entered.
In this case, contact your after-sales service
.
To deactivate the device, pleas press and hold the button for three seconds.
Always ensure that the device makes the proper detection response to the pertinent
gas. Verify that debris that could interfere with the detection of gas are not blocking
the area where gas is to be detected

6.1 Measuring mode
When activated, in Measuring mode, gas concentration will appear on the screen.
Oxygen concentration is displayed in percent by volume (%Vol) and toxic
concentration is displayed in parts per million. (PPM).
6.2 Display mode
In Measuring Mode, by pressing button for one second, the following ICONs will appear in
order.
MIN. (min value, only for oxygen) →MAX. (max value) →CLR (clear data) →1st alarm set point →
2nd alarm set point →Firmware version →Remaining calibration day →Calibration Concentration
At the last step, if you press button or do not push any button for a second, the device will return to
Measuring Mode.
6.3 Alarm Activation & Setting Alarm set points
When the gas concentration exceeds alarm set points, or will be displayed and the device will
vibrate, flash (LED), and beep. To remove alarms, move to a clean air location. and then a gas concentration
will decrease, and alarm will stop.
To set the alarm setpoints, please follow the steps below:
-Press the button until the above alarm setpoint is displayed.
-Press and hold the button for three seconds and the first digit of alarm setpoint starts to
blink.
-To increase the value, press the button for one second.
-To save the alarm setpoints, press the button for 3 seconds.
*Ensure that the second alarm set point must be greater than first alarm setpoint.
* Ensure Standard Factory alarm set points vary depending on countries, states, and
companies. Before changing alarm setpoints, please ensure the alarm set points are in
compliance with your local guidelines.

Last 30 events are stored on a device. Once more than 30 events are stored, the log events are removed
automatically in the order starting at Event 1.
Each alarm event records followings: Types of alarms (1st or 2nd) / Alarm concentration in ppm or % / Peak

8Calibration
Initial calibration is performed on all devices prior to shipment. Once received,
calibration should be performed monthly (or quarterly) depending on frequency of use.

Fresh air calibration Standard gas calibration
8.1 Fresh air calibration
When pressing and holding the button for 5 seconds in the calibration mode, ( ), icon and “CAL”
mark will appear on the LCD. And, press the button to initiate calibration for three seconds. When
calibration begins, a countdown (starting at 10) will appear on the screen.
Once completed, icon will appear on the LCD.
If calibration fails, icon will appear on the display.
If this continues, please contact the distributor of the device or the after-sales service.

Calibration should be performed in a fresh-air environment that is free for any influence
of other gases (since calibration is assumed to be performed in an environment with
20.9% of Oxygen). It is also recommended that calibration should be performed in a
space that is not confined.
8.3 Standard gas calibration
When pressing and holding the button for 5 seconds in the calibration mode , icon and ‘CAL’
mark will appear, and when pressing button once again, icon will appear. And then, press and hold the
button for three second to initiate calibration. When calibration begins, a countdown (60 seconds or more
depending on sensor types) will appear on the
