AIRPRO™ AIR VELOCITY
INSTRUMENTS

MOBILE APP, FEATURE SETS, VELOCITY METER,
AND MEASUREMENT PROBES

AirPro™ Air Velocity Instruments are rugged, compact, congurable and highly
accurate measurement devices featuring a Velocity Meter (AP500), Mobile Application
Software (AP-MOBILE), and user-dened Measurement Probes (VT-S, VT-A, VTH-S,
VTH-A and TH-S) and Feature Sets (APFS-B, APFS-A and APFS-P).

Measurements are taken via trusted thermohygrometer or themoanemometer
technology, displayed locally at the meter and simultaneously transmitted,
via Bluetooth®, to your mobile Android or iOS handheld device for use with
AirPro Mobile Application Software. Instrument features are enabled
remotely based on user preference.

Applications

+ HVAC testing and balancing
+ Clean room testing
+ Biological safety cabinet and laboratory fume hood testing
+ HVAC commissioning and troubleshooting
+ Ventilation evaluations
+ Face velocity measurements

Features and Benets
+ Multiple plug and play probe congurations available
+ Stackable probe extensions allow for additional reach
+ High contrast display eases viewing in dimly lit areas
+ Best-in-class air velocity accuracy
+ Long life rechargeable Li-ion battery reduces cost of ownership
+ Calibration certicate included
+ True single-hand operation
