 VELOCITY, VOLUME AND EXCEPTIONAL VERSATILITY
The Airflow AV2 air velocity and volume flow meter represents the latest advance in hand
held vane anemometers. The unique combination of air velocity and air volume flow
readings at the push of a button, provides the user with unrivalled versatility and choice
from a single anemometer.
AV2 is extremely user friendly with all functions accessed from the logical front switchpad.
The large clear LCD display can be read at a glance and incorporates on-screen function
indicators to ensure all measurements are easily understood. Once the operators choice of
metric or imperial display is selected the next option available is to choose the mode of
reading. Two modes are offered: CONTINUOUS or AVERAGING.
In CONTINUOUS reading mode, spot measurements are easily taken with updated readings
continually displayed until the READ button is pressed to hold the last indicated value.
In AVERAGING reading mode, time saving scanning measurements are possible with
readings constantly updated to display the running average value. By pressing the READ
button in this mode the average reading for the duration of the test is held.
Both CONTINUOUS and AVERAGING mode have a maximum test period of 180 minutes, at
any time during which the operator can ‘HOLD’ either the latest or average values on the
display. The versatility of such a wide time span allows the operator flexibility to quickly
scan, traverse slowly or even leave the vane sensor in position in the airstream for short
term monitoring.
However, the really exceptional feature of AV2 is the ability to measure directly not only air
velocity but also to instantly display actual AIR VOLUME FLOW. By simply entering the area
of the grille, duct or opening to be monitored, direct readings of air volume will be displayed,
in either m³ sec or cfm.
An analogue output is also incorporated as standard so that measured values may be
downloaded onto a compatible printer or data logger such as the AirflowTM AM2.
The instrument is equipped with an industry standard 100mm (4") diameter rotating vane
sensor. A compact, interchangeable 35mm (1.4") diameter rotating vane sensor is also
available as an optional extra. AV2 is supplied complete in an impact resistant, protective
case to withstand the rigours of on-site use, which has compartments for both sensors, a
spare battery (not supplied) instruction booklet and telescopic extension handle. Designed
with site testing in mind the telescopic sections provide rigid support and extend to 1.1m in
length. The tip incorporates a lockable ‘all angle’ swivelling joint for easy and accurate
alignment of the vane sensor to the airstream in even the most awkward positions.
An extremely helpful option is the AIRCONE kit. An inexpensive kit containing a circular and
rectangular moulded hood for air balancing which simply clips onto the vane probe to
provide direct air volume flow readings from grilles, linears and diffusers.
Calibrated to an Internationally recognised standard the AV2 is supplied with a FREE
TRACEABLE CERTIFICATE OF CALIBRATION and a reply card is also included for
purchasers to register with our FREE annual calibration reminder service.
All AirflowTM instruments, including the AV2, are designed to help meet the stringent
requirements of the Control Of Substances Hazardous to Health (COSHH) and Building
Regulations in the UK.
For our UK customers the reminder card service ensures valid certification for COSHH,
ISO9001 and Quality Assurance requirements.
