Powering
the
Meter
This meter can be powered by four (4) AA size batteries (not included) but sampling units can also be powered by
the included 6VDC international wall power supply. These units should NOT be powered using the included USB
cable since it supplies inconsistent voltage to the meter, which degrades sensor accuracy.
If the unit is not going to be used for an extended period of time, batteries should be removed to prevent damage
due to potential battery leakage.
The power switch
on the left side of the meter turns the unit ON/OFF. The LOG switch on the right side of the
meter enables/disables data logging and pump function.
Product
Overview
This portable battery‐powered CO2Meter, Inc. meter is designed to measure carbon dioxide (CO2) in real time in
inaccessible areas for applications such as, but not limited to fermentation vats & barrels, biological incubators,
and CO2 leak detection.
Meters with logging capabilities are designed to record CO2 concentration level data over periods of time. It stores
up to 15,000 collected data points to its internal memory to be retrieved at a later time for analysis. When
combined with our GasLab
®
software, you can also see real‐time data on your computer’s screen. These meters are
ideal for applications such as, but not limited to CO2 monitoring of products with modified atmosphere packaging
(MAP), monitoring of mold production in areas used to store grains, and testing of fire suppression systems.
Its built‐in 1,000 hours sampling micro‐pump (10,000 Hr. optional) ensures reliable operation for persistent
readings based on user‐selected time intervals.
Scientific devices such as this sampling meter require users to have intimate knowledge of the meter’s features,
limitations, operation, required software, and specifications prior to use. CO2Meter, Inc. highly recommends
reading this user’s manual before operating this meter, especially the
Important
Safeguards
section on page 4.

Data
Storage
This meter features an internal memory capable of storing 15,000 data points. Due to the nature of their design,
these meters will need to be initialized before operation and its logging period and real‐time clock will need to be
set under the “Settings” menu.
Logging
Data
Once the GasLab
®
software has been installed and the meter is connected to the computer, you can gather data in a
variety of ways. Data can be collected in real time, data logs can be downloaded from the meter’s memory and
saved to the computer, and data can be reviewed on the meter’s LCD display.

1. Turn the meter ON.
2. The meter must be started at least 1 minute prior to deployment and data logging to allow the CO2 sensor
time to warm‐up and calibrate.
3. Set the logging interval as desired and commence logging by depressing the “Log” button on the right side
of the meter.
4. When data logging is completed, turn the “Log” OFF.
NOTE:
Refer to the GasLab
®
User’s Manual for more information.
Setup
CO2Meter, Inc.’s sampling meters will require minimal setup since they are designed to be portable. The most
important aspect of the setup involves connecting the sampling hoses and ensuring proper setup. The
Instrument
Overview
section on page 8 shows the labeled components of these meters, as referenced throughout the rest of
this manual.
Data
Logger
Models
These models feature an internal memory capable of storing data when not connected to a computer. These units
will allow you to simultaneously read and store CO2 concentration level data. Due to the nature of their design,
these units should be connected to your computer first, before operation, in order to initialize and set the logging
interval and real‐time clock.
Insert four (4) AA size batteries into this unit or connect the unit to the included power supply. In order to initialize
data logging functionality, the unit MUST be connected to the computer with data logging switched to OFF, and the
GasLab
®
software started. Once the unit has been connected, click on the “Configure Sensor” button in the GasLab
®
interface, set the data logging interval and pump periods as desired. We recommend leaving the pump interval to
the default 10‐second period. For the pump period, we recommend 10 or more seconds.
The pump PWM period can also be adjusted for advanced applications, with 1 being full duty cycle, and values
approaching 255 being the shortest duty cycle. The pump mode should always be set to “Data logging” for proper
operation of the unit.
All models have an internal coin cell CR‐2032 3V battery backup for the real‐time clock. This battery is inserted in
the factory for your convenience and should last the lifetime of the product.

In order to use this meter properly, hoses/tubing must be attached to the inlet and outlet barb fittings securely.
The pump will draw air from the inlet by vacuum effect, push it to the sensing chamber through the sensor, and
then exhaust the air outside the meter through the outlet.

1. Install fresh set of AA batteries (Duracell brand recommended) or connect the included power supply.
2. Install filters and tubing included as shown on Figure 6.
3. Turn the meter ON by pressing the power switch once.
4. Turn logging ON by pressing the LOG switch once. Once the sampling process is completed, data can be
downloaded to your computer using our GasLab

software.
Calibration
All units are factory‐calibrated with multiple reference points of gas, and have been verified to be accurate within
their specific functionality before shipment. However, if the unit is severely jolted or otherwise mechanically
disturbed, the sensor can drift requiring recalibration. All calibration procedures follow a single‐point calibration
routine that effectively shifts the zero‐point of the CO2 sensor.
Supply calibration gas to the unit and connect the unit to a personal computer. Open the calibration screen in the
GasLab
®
software. Click the
CALIBRATE
button in the calibration tab for the desired gas, located in the
CONFIGURE
SENSOR
screen. As long as the gas concentration is stable, the unit should instantly reflect the
calibrated value. This can be confirmed by watching the display. To see the calibration value in real time, click in
the
COLLECT

Calibration can be performed using either 100% CO2 calibration gas (typically nitrogen, argon, etc.), or using a
fresh source of air, assumed to be approximately 400ppm.
NOTE
: Refer to the GasLab
®
User’s Manual for complete instructions.
Calibration
Procedure
To calibrate your meter, follow these steps:
1. Turn ON the meter.
2. Expose the meter to ambient air (assumed to be at 400ppm) or supply calibration gas bottle/cylinder
(100% nitrogen or argon) with the appropriate demand regulator.
3. Wait 25 seconds to collect a sample. Write down this value as the “before” value.
4. Click the
CALIBRATE
button after selecting your calibration gas.
5. Wait 25 seconds again. This time, the meter will take a sample and use this data to adjust zero values. The
displayed measurement will show the new calibration value (0 or 400ppm, depending on method used).
6. Disconnect the Calibration gas and wait 25 seconds. All displayed data will now be based on the new
calibration value. Repeat this procedure if the sensor is still operating outside of its specified range or if
readings vary greatly.

These models do not feature Automatic Background Calibration (ABC) algorithm due to the CO2 scale they
measure. To ensure the highest accuracy, we recommend calibrating these units with calibration gas (Nitrogen for
ZERO or CO2), close to the concentration being measured. Alternatively, a 100% or ambient calibration can be
performed.
To perform a calibration, attach the unit to your computer, power it with the wall adapter and either expose it to
atmosphere or supply it with your calibration gas, fed with a demand‐based regulator.
Open the GasLab
