Features:
Flowrate feature makes simple calculations of volumetric flow rate when the user inputs the duct shape and size, K factor or horn size
Velocity measurements are made from the thermal sensor or a Pitot tube
Automatic conversion between actual and standard velocity readings
Direct calculation of dew point and wet bulb temperature - no psychrometric chart needed (Model 8386 only)
Heat flow function calculates heat transferred after a heating or cooling element (Model 8386 only)
Stable digital display when measuring fluctuating flow
Backlit display is easy to read in poor lighting conditions
Switchable from Imperial to metric units via dip switch located on rear of unit (all units shipped reading Imperial units)
40-inch telescoping probe with etched length marks to make duct traverse measurements easier
Optional portable printer provides hard copy documentation of your measurements
