AQ EXPERT OPTIONS
The E INSTRUMENTS
’ AQ EXPERT is an extremely versatile Indoor Air Quality (IAQ)
measurement system that meets practically all Air Quality measurement requirements.
It has been designed as a modular system, permitting the installation, in the field, of
most of the various available options. This manual describes the complete instrument
equipped with all the options.
The AQ Expert’s standard capabilities include (1) NDIR CO
2
sensor (0-5,000 ppm),
Ambient Temperature, Relative Humidity, Wet Bulb, Dew Point, Barometric Pressure,
two (2) separate Type K (TcK) thermocouple temperature measurement inputs, Air
Velocity measurements, differential pressure measurements, 1000 internal storage
tags, Bluetooth wireless PC communications, REAL-TIME Data Logging capabilities
using the included AQ GAS Windows
TM
software, USB Cable, and extensive user-
friendly help screens. The available additional gas sensor options and accessories are:
1. AIR QUALITY MONITOR SENSORS*
•
Carbon Dioxide (CO
2
)
– non-dispersive infrared (NDIR) sensor (0-20%)
•
Carbon Dioxide (CO
2
)
– non-dispersive infrared (NDIR) sensor (0-5000 ppm)
•
Carbon Monoxide (CO)
– electrochemical sensor (0-200 ppm OR 0-2000 ppm)
•
Oxygen (O
2
) - electrochemical sensor (0-25%)
•
Nitrogen Dioxide (NO
2
) - electrochemical sensor (0-20 ppm OR 0-1000 ppm)
•
Nitrogen Oxide (NO) - electrochemical sensor (0-250 ppm OR 0-2000 ppm)
•
Sulfur Dioxide (SO
2
)
– electrochemical sensor (0-20 ppm OR 0-2000 ppm)
•
Hydrogen Sulfide (H
2
S)
– electrochemical sensor (0-100 ppm)
•
Formaldehyde (FMH-CH
2
O)
– electrochemical sensor (0-10 ppm)
•
Ozone (O
3
)
– electrochemical sensor (0-5 ppm)
•
Isobutylene (VOC) sensor
– Photo ionization detector (PID Sensor) (0-20 ppm)
•
Isobutylene (VOC) sensor
– Photo ionization detector (PID Sensor) (0-200 ppm)
*Note
: When O
3
(Ozone) sensor is installed the AQ Expert can include O
3
+ NO
2
OR
O
3
+ SO
2
.
The unit can
NOT
have all three (3) sensors (O
3
+ NO
2
+ SO
2
) together simulatenously.
2. OPTIONAL EXTERNAL MEASURING PROBE
Certain applications might have the need for the optional
probe (12” long stainless steel probe with 10’ ft long hose) for
hard to reach places, separate areas, etc. The probe
consists of the stainless steel extraction probe, the sampling
line and a Type K thermocouple for external temperature
measurements with the probe.
