GasLab SAN-100 Micro Carbon Monoxide Monitor
User Manual
The GasLab SAN-100 is a wearable, personal safety meter designed to monitor ambient
concentrations of carbon monoxide (CO) in real time. CO gas poisoning is the most common
type of fatal poisoning in the world.
Features
•Silicone boot and metal clip are light and comfortable to wear.
•Electrochemical sensor, no consumable parts.
•Displays peak CO level until reset.
•Lithium-ion rechargeable battery. USB Charging port.
•Runs 10+ days per charge.
Applications
•Heating and Ventilation. CO is produced by oxygen-starved combustion in improperly
ventilated fuel-burning appliances such as oil and gas furnaces, gas water heaters, gas
ovens, gas or kerosene space heaters, fire places and wood stoves.
•Internal Combustion Indoors.CO is produced by all internal combustion engines. This
makes the SAN-100 useful in garages, car parks, venues, repair facilities or job sites where
cars, trucks or machinery is run indoors. Portable power generator use indoors.
•Fire Fighters. CO is produced naturally in trace amounts by the partial oxidation of methane
in the atmosphere, volcanoes and forest fires.
Please take a moment to read these instructions before use. They will provide you with
all the necessary information for the correct use of your carbon monoxide monitor.

Theory of Operation
The SAN-100 Carbon Monoxide Monitor uses an electrochemical sensor to determine the
concentration of carbon monoxide in air. Air reaches the sensor by diffusing through the vent
holes (see item 6 below). Normal air movement is enough to carry the sample to the sensor.
Device
1. OLED display
2. Power button
3. Indicator LED
4. Micro USB charge port
5. Vent holes
6. Clip
7. Silicone boot
OLED Display
1. Carbon Monoxide concentration
2. PPM – parts per million
3. Battery Charge Indicator
4. Peak (max) reading
Note: The peak reading on screen displays the highest concentration of CO detected since the
peak was last reset. To reset the peak reading, press Power button to restart the device.
OPERATION
Plug the USB cable into the meter and a 120VAC wall adapter. It will take approximately 2
hours to receive a full charge. Once the meter is charged, it can run 10+ days before
recharging.
Press the power button to turn on the meter.
When the meter is first turned on, it performs a 3 second countdown for device warm up, then
enters normal display with current carbon monoxide readings displayed. The device starts
taking measurements when powered on and updates readings every 3 seconds.
The OLED display will turn off automatically after 120 seconds of inactivity to conserve battery
power. However, the sensor will continue to monitor the CO level. Briefly press the Power
button to view the display.
Hold down the Power button for 3 seconds to turn the meter off. This will conserve the battery’s
charge until you need to use the meter again.

Low Battery Alarm
The meter continuously measures the rechargeable battery voltage. If it drops to a critical level,
the low battery alarm will sound until the battery is recharged or the battery power is depleted.
Note that the meter can continue to monitor CO levels while charging.
CO SENSOR CROSS-SENSITIVITY
Electrochemical sensors are cross-sensitive to specific gases other than the target gas of
interest. While cross-sensitivities are limited, as much as possible by sensor design, some
interactions still exist. The table below shows the most common cross-sensitivities.

If the meter is exposed to one of the above gases, it will clear itself if you expose it to normal
outdoor air for 30 minutes. Do not expose the device to the fumes of inorganic solvents (e.g.,
paint fumes) or organic solvents.

CLEANING AND STORAGE
The front panel and case can be cleaned with a mild solution of detergent and water. Apply
sparingly with a soft cloth and allow drying completely before using. Do not use aromatic
hydrocarbons or chlorinated solvents for cleaning.
TROUBLESHOOTING GUIDE
Symptom / Issue
Possible Cause / Resolution
Device does not power ON
Make sure the power supply is connected properly and
that there is power at the outlet. Use the supplied adapter.
Verify that your meter has had enough time to charge
before turning it on.
Reading does not change In fresh air, you will rarely see CO levels above 1%. This is
normal.
CO RECOMMENDED LEVELS
•< 1ppm Average CO level in fresh air
•9ppm Maximum recommended indoor CO level (OSHA)
•25ppm Maximum TWA Exposure for 8 hour workday (ACGIH)
•50ppm OSHA long-term workplace exposure limit
•50-100ppm Symptoms of mild CO poisoning include headaches and dizziness
•700ppm Life-threatening CO levels
