Section 1 - Introduction
The HHF1000 series handheld air velocity/temperature meter measures
and displays air velocity mass flow and air temperature of clean air flows in
ducts & pipes, while producing very little pressure drop in the flow stream.
The HHF1000 series can be used in research & development labs, HVAC
applications, and other manufacturing processes. The sensor design is based
on three RTD elements, one measures the air temperature and the other two
measure the air velocity. The air velocity is measured based on the heat loss from
the RTD velocity sensor as it cools down by the air flow.
The HHF1000 series offers many standard features such as dual display of air
velocity & temperature, high & low alarm indications for air velocity, volume
air flow measurement, USB PC interface with a Windows based PC interface
software. The HHF1000 displays the air velocity in feet per minute (FPM), meter
per second (m/s), miles per hour (MPH), and kilometer per hour (Km/h). The
air temperature is displayed in ºF & ºC. The volume air flow is displayed in
Cubic Feet per minute (CFM) and Cubic meter per minute (CMM). The sensor
probe is 12" long as standard. The 304 Stainless steel sensor tubing is provided
with inch marks for ease of insertion depths. The sensor probe comes in two
different versions as follows:
The unit powers from a 9V battery or a 9Vdc adapter.
The following table shows all the models of this product:
