Ideal for measuring all parameters, including airflow volume and enthalpy of evaporation, needed to install, test and fine-tune the performance of an HVAC/R system.

Ideal for HVACR technicians and contractors, the DAF3009 offers the ability to measure eight HVACR-related parameters in one handheld device that is small and light enough for one-handed operation.

The DAF3009 can measure all parameters associated with installing, testing and fine-tuning the performance of an HVACR system:

• Airflow Volume (in CFM or CMM)
• Air Speed (in ft/min, m/sec, km/hr, mph or knots)
• Enthalpy (in Btu/lb or kJ/kg)
• Ambient Temperature
• Dew Point Temperature
• Wet Bulb Temperature
• Wind Chill Index
• Relative Humidity
• The instrument not only can measure air speed and airflow volume, but also can track and calculate the maximum, minimum and average values recorded over a measurement “session.” A session begins when the device is powered on and ends five minutes after the final measurement is made (when the Auto Power Off function activates). This capability is helpful for a variety of purposes, such as determining the fastest and slowest fans in a group or the average of a group of fans.
