  • Measures air velocity in m/sec, ft/min, km/hr, knots or mph
  • Measures air volume in m3/min or ft3/min
  • Measures temperature °C or °F
  • 55mm LCD display with backlight and function indicators
  • Data hold and min/max hold for airflow and temperature
  • Low battery indicator
  • Auto power off after approx. 20 minutes of inactivity – can be user disabled
  • Average calculated from the last 10 airflow readings
  • Standard ¼" camera bush for tripod mounting
  • Supplied with hard carry case, telescopic probe, AC/DC power adaptor and battery
