Ideal for applications where common vane anemometers won't fit, the pitot tube included with the HD350 allows navigation into difficult ducts and other HVAC applications in order to measure air velocity, air flow and overall pressure inside ventilation.
A dual function instrument, the HD350 is capable of showing testing results simultaneously and can show a pressure, air velocity or air flow value plus a temperature reading at the same time. It also includes multiple testing units and when measuring pressure users can choose between psi, mbar, inH20, mmH20 and Pa measurement modes, while air velocity measurements can be calculated in ft/min, m/s, km/h, MPH and knots. Both CFM and CMM air flow measurements are also possible and temperature can be calculated in either Celsius or Fahrenheit.
The HD350 also contains the ability to log testing data and can store up to 99 readings in each mode for easy recall at a later date. It is also possible to send this data over to PC by connecting a USB cable to the device and porting it into the included software package.
Additional functions of this device include MIN/MAX/AVG parameter calculation, relative time stamping, data hold, auto power off and a backlit LCD screen for using the meter in darkened areas.
