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 60,000 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

Principal of Operation
The CO2 sensor inside this meter uses proven NDIR (non‐dispersive infrared) technology to sense, as a function of
transmitted light, the concentration of CO2 in the air.
Air from the tube inlet port is pulled into the sensor’s CO2 molecule detection chamber by a micro‐pump, then
expelled out the tube outlet port.
The measured CO2 level is shown on the LCD in real time and/or logged into memory with a date/time stamp for
later retrieval.
The meter is factory calibrated to operate within the specified range and precision.
