2.2 General Description
Thank you for purchasing our YESAIR, a multi-sensor, battery powered, handheld
air quality detection and data logging instrument designed for intermittent or
continuous indoor air quality monitoring. It can be handheld, fixed to a wall or set
on a desk or tripod.
The YESAIR is available three models:
YESAIR Pump that draws in sample air through a nozzle with an internal pump on
the top of the unit.
YESAIR Diffusion that works by sample air passing through the sensor openings
by natural circulation of air on top of the unit.
Dual Probe that draws in sample air using the internal pump, through an attached
temperature and relative humidity probe and high humidity gas probe. This model
is specifically for CO
2
and O2 sampling in high humidity environments such
incubator chambers and horticultural applications (greenhouses, mushroom farms,
etc).
NOTE: Specific Dual Probe model information can be found in Section 10 in
this manual. The rest of this manual is devoted to the Pump and Diffusion
models and shared specifications of all three models.
The Pump and Diffusion YESAIR models are equipped with a top mounted
temperature and relative humidity sensor to aid in verifying readings, providing a
comprehensive indication of air quality. The Dual Probe model comes with a
handheld temperature/relative humidity probe and a high humidity gas sampling
probe, both of which attach to the top of the instrument.
Sensor readings, battery level and data logging status can be viewed live on the
multi-line, backlit, LCD display. The YESAIR can reliably record time-based
information, which can be downloaded via a USB port. Any computer capable of
running Microsoft Windows 2000 or higher (with an available USB communications
port) can accommodate CETCI’s proprietary YES Viewer Software. The YES
Viewer Software allows users to analyze and graph the data.
In addition to the temperature and RH sensors, the YESAIR can handle up to 5
additional internal plug & play sensors consisting of a maximum of 3
electrochemical toxic gas or oxygen sensors, and 2 high current draw sensors such
as an infrared PID or catalytic sensor, plus 1 remote particulate sensor such as the
YESDUST. Choose from a selection of up to 30 different sensors to best suit your
application specifications. Reference the list of available sensors under 4.2 Plug &
Play Sensor Gas Types.
Most of the sensor modules can be changed in the field and are operable within
minutes (accurate readings will require more time as each sensor type has a
Rev. K | 2018.02 YESAIR Operation Manual

different warm up / stabilization period before they are able to perform to publish
specifications).
An optional gas sampling probe is available with the Pump model. The probe has
a 10 in / 25.4 cm wand and 30 in / 76 cm of tubing that fits onto the nozzle and
allows you to reach into areas that are difficult to access.
Calibration and repairs are available at our manufacturing facility and through some
of our authorized and trained Distributors.
If after reading through this manual, you have any questions, please do not hesitate
to contact our Service Department for technical support.

4 SENSOR SPECIFICATIONS
4.1 Overview
The YESAIR has the capacity for 7 internal sensors – one temperature sensor,
one RH sensor and 5 plug and play gas sensors; plus one remote sensor such as
the YESDUST Particulate Sensor.
The YESDUST is connected via the auxiliary port and is a general purpose
particulate sensor that counts particulates between 1 and 10 microns in size. The
YESDUST uses the YESAIR’s data logging capabilities to record data and adds
this information to the log file along with the YESAIR’s data records. If you would
like more information on the YESDUST please visit our website.
NOTE: Neither the YESAIR nor the YESDUST are intended for use in clean
room applications.
The YESAIR has plug and play smart sensors and placement of those sensors is
an important consideration. With the display facing you, look at the top of the
YESAIR and you will see five gas sensor sockets. The three sockets closest to the
back edge are for electrochemical toxic gas sensors, with SLOT 2 configured
specifically for an Oxygen sensor. SLOTS 4 and 5, towards the front edge are for
CO2, PID or combustible gas sensor types. If a Nitric oxide (NO) sensor requiring
electronic bias within the circuit is used, it must be fitted to one specific sensor
location (left rear position, determined by looking at the front of the instrument).
Two sensors requiring bias cannot be fitted in the same instrument at the same
time. Reference the photo in 9.2 Sensor Location Restrictions.
Sensors can be added or changed as required. However, an instrument that is
configured for Nitric oxide, Hydrogen chloride, Ethylene oxide, Hydrazine or
Formaldehyde cannot be swapped with a different sensor type without hardware
modification and cannot be placed in any other socket than SLOT 1 or 3. If this
change is desired, the unit needs to be sent back to the factory to be reconfigured.
Sticky gas sensors (ie. Chlorine (Cl
2
), Hydrogen chloride (HCl), Ozone (O3),
Hydrogen fluoride (HF), Fluorine (F
2
)) used in the Pump model should be installed
in SLOT 1, closest to the inlet port for calibration. The shorter the distance the
sticky gas needs to travel, the more accurate the calibration will be.
If the YESAIR is ordered with only a couple gas sensors, the unused sockets will
be populated with a dummy sensor plug to ensure a good seal and circulation of
air for sensing purposes. The dummy sensor plugs can be removed and replaced
with gas sensors as mentioned above, and vice versa. To remove a dummy
sensor plug, gently push inwards and turn, releasing the plug from the socket.
See section 9.1 Dummy Sensor Plugs.

NOTES:
1. Not all of the above sensors are available from stock. Delivery time for sensors
ordered will vary depending on which sensors are ordered, how many are
ordered and measurement range desired.
2. Other measurement ranges are available for some sensors. Contact factory
with desired range to confirm availability.
3. Some of these sensors must be calibrated with correlation gases because they
are more readily available. If the customer wishes them to be calibrated with
the exact target gas, extra charges will apply to acquire the specific gas if and
when available. In these cases, customer will be required to take delivery of
the special cylinder of span gas and dangerous goods and shipping costs will
apply.
4. Some of the above sensors have cross sensitivities to other gases (interfering
gases). Please refer to the sensor specification chart before ordering a specific
sensor if your application may have some of the interfering gases present.
