Rotating Vane Anemometer
with Data Logging

Comprehensive, professional grade, rotating vane anemometer with 
data logging  and turbulence indication

Features of the AL RVA series Air Velocity
flow and temperature Logger

  • Air velocity - m/sec, ft/min,
  • Airflow - m3/sec, ft3/min
  • Temperature - °C, °F
  •  Auto shut off conserves battery life
  •  Ideal combination of air velocity, volume flow and temperature
  •  Excellent accuracy with fast, effective processing power
  •  Perfect for both on-site checks and unattended monitoring
  • Simply enter area or linear dimensions to read volume flow
  • Ideal for HVAC, process control, laboratory safety, quality assurance, R & D engineers and indoor environment monitoring.
  • Articulated telescoping handle optional
Rotating Vane Anemometer
The RVA series offers a complete airflow measurement system with built in data logging. Fast accurate measurements of air velocity, volume flow and air-stream temperatures are integrated with advanced microprocessor technology to provide powerful processing and data collection. Digital outputs support direct compatibility with micro printers and WINDOWS® software. The standard unit has a 4" diameter vane.
