HHF1000 SERIES
Handheld Air Velocity/Temperature Meter

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:
• Fixed 12 inches long Probe
• Telescopic probe adjustable from 10 to 36 inches
The unit powers from a 9V battery or a 9Vdc adapter.
The following table shows all the models of this product:

Important considerations before installation
The HHF1000 air velocity/temperature meter is not explosion
proof, nor is it Intrinsically safe. Do not use for flammable or
hazardous gases, or in Hazardous areas.

Introduction 1
NOTE:

The HHF1000 series air velocity/temperature meter is intended for use with
clean air or Nitrogen ONLY. Do not use with other gases, as it will produce an
un-calibrated and non-linear display measurement. In addition, air carrying dust
or oil (such as found in blower/compressor systems that utilize oil) can lead to
coating of the sensor and thus inaccurate readings. Refer to the Maintenance
section (page 4-3) for information on cleaning the sensor.
The HHF1000 is a bi-directional device, meaning the air flow in the forward or
reverse direction provides the same readings.

Section 2 - Installation
1. Install the 9V battery in the battery compartment of the case. You can remove
the battery door to get to the compartment.
2. Remove the protective cap from the sensor tip.
3. Run a length of straight pipe before and after the flow sensor probe. The
amount of upstream straight pipe required depends on the type of obstruction
which is immediately upstream of the flow sensor. See Table 1 (on next page)
for specific requirements. Downstream of the flow sensor, in all situations, run
5 diameters of straight pipe regardless of the downstream obstruction.
4. Align the sensor probe with the air flow. Make sure the air flow is
perpendicular to the sensor window. The score line on the sensor tubing
is another way of aligning the sensor to the flow stream. The score line
starts from the center of the sensor window and as a result it can be aligned
properly.
5. One way of installing the sensor probe into a flow stream is to utilize a
compression fitting such as Omega’s SSLK-14-14 stainless steel compression
fitting with Teflon ferrule, which allows adjustment of the insertion depth of
the probe.
6. Turn on the power switch and start measuring air velocity & temperature.
