SECTION 1

General Description

The Model IAQ10 is a hand-held meter to
measure Carbon Dioxide (CO

), displayed

2

in units of parts per million (ppm). An
NDIR sensor in the top end of the meter
measures gas content by diffusion through
sensing holes.

The IAQ10 ships in a pouch that provides a
small amount of protection to the display
and the sensing holes in the top of the
instrument case. The instrument ships with
batteries (which are not installed), a
calibration sheet, and this Owner’s Manual.

SECTION 2

Theory of Operation: NDIR Sensor

The IAQ10 measures carbon dioxide
concentration by relying on one of the
natural properties of CO

molecules: CO2

2

molecules absorb light at a specific wave­length of 4.26 µm. This wavelength is in the
infrared (IR) range. High concentrations of
CO

molecules absorb more light than low

2

2

concentrations. This technique is called
non-dispersive infrared (NDIR) detection.

SECTION 3

Safety

When using the IAQ10 to check for CO

2

values, make certain that you can safely
raise and hold the instrument while
making measurements. Be especially
careful when working on a ladder.

Observe all necessary precautions so that
the unit does not become caught in moving
machinery or touch any exposed electrical
wiring.

DANGER!
Use with corrosive or other dangerous or
explosive gas mixtures is not recom­mended.

SECTION 4

Setting-Up the Model IAQ10

Supplying Power

The IAQ10 can be powered in one of two
ways: four AA-size batteries or the optional
AC adapter.

Installing the Batteries

Insert four AA batteries as indicated by the
diagram located on the inside of the battery
compartment. The Model IAQ10 is de­signed to operate only with alkaline
batteries. When 15% battery life is remain­ing, the battery indicator will blink,
indicating the batteries need to be changed.

At 0%, “LO” will display and the meter will

shut off within 10 seconds.

Using the Optional AC Adapter

The optional AC adapter allows you to
power the Model IAQ10 from a wall outlet.
When using the AC adapter, the batteries
(if installed) will be bypassed. The AC
adapter is NOT a battery charger.
