INTRODUCTION
The DAFM4 Anemometer/Psychrometer is designed with 6 HVAC/R
parameters in one instrument. These are included in a portable, battery-
operated instrument for measuring humidity, air temperature, dew point,
wet bulb, air velocity and air volume. The small vane probe includes
sensors for velocity, temperature and humidity all on a telescoping
extension, making in-duct and surface measurements possible.
FEATURES
• Measures air velocity, temperature, and relative humidity (RH%)
• Calculates wet-bulb temperature, dew point, and air volume
(CFM, CMM)
• 0.7” Small diameter air vane on 39” long telescoping probe
• Timed accumulative average for air volume with one hour maximum
• Min/Max and Hold
• English/Metric Scales
• Fast response
• Auto-power off (can be disabled)
• Low battery indicator
INCLUDED
• DAFM4 Meter
• Remote telescoping mini-vane probe
• Battery (1 x 9V)
• User manual
• Hard carrying case
