UEI DAFM3B Digital Air Flow Meter

The DAFM3B anemometer/psychrometer is designed with six HVAC/R essential parameters in one instrument. Conveniently combined into a portable, battery-operated instrument for measuring relative humidity, air temperature, dew point, wet bulb, air velocity and air volume

Features

• Measures air velocity, temperature and humidity
• Calculate wet bulb, dew point, and air volume (CFM, CMM)
• Up to 1 hour accumulative average
• Handheld size, easy to carry
• English / Metric scales
• Auto power off selectable
• Low battery indication
• Professional remote vane
• Protective twist cap for temperature/humidity sensor
• 1 year limited warranty
