1. OVERVIEW
1.1. General Description
Thank you for purchasing the IEQ Chek™ indoor environmental quality monitor. The
IEQ Chek™ is an easy-to-use, portable, information-recording device for monitoring
trends that pertain to indoor air quality.
The IEQ Chek™ is a battery-powered, portable, indoor air quality monitor and
information recording (data logging) instrument designed for both intermittent and
continuous operation. Its intended use is for indoor environments. A basic instrument
includes a multi-line LCD alpha numeric display, audible alarm, rechargeable
batteries, temperature and relative humidity sensors, and operation manual.
The IEQ Chek™ is equipped with top-mounted temperature and relative humidity
sensors to aid in verifying readings providing a comprehensive indication of air quality.
Information readings can be written to a plug-in (and removable) flash card to protect
your recorded information. The sample rate can be adjusted using the supplied
software or through the instrument menu. The instrument may be hand held, stood
upright on a flat surface, or fastened to a wall for permanent or semi-permanent use.
The IEQ Chek™ series of instruments are
manufactured with plug-and-play,
interchangeable sensor modules to allow for
the testing of multiple gases. The
specifications listed in this manual indicate a
wide array of supported sensors. These
sensors may be changed in the field and
operated within minutes (accurate readings
will require more time as each sensor type
has different warm-
up/stabilization periods
before they are able to perform to published
specifications).
NOTE: Calibration and repair are available at
our manufacturing facility and through some
of our authorized and trained distributors.
The IEQ Chek™ can reliably record time-
based information, which can be downloaded
via the USB port located on the right side of
the instrument. Any computer running
Microsoft Windows XP or higher (with an
available USB communications port) can
accommodate
the optional IQ Chek™
software.
If after reading the manual you have any
questions, please contact our service
department for technical support.
