Features
The OMEGA™ HHF-SD1 combination hot wire and standard thermistor anemometer with SD card data logger has multiple features that make it suitable to use in such applications as environmental testing, balancing of fans/motors/ blowers, air conveyors, clean rooms, and flow hoods. What sets the HHF-SD1 apart from other hot wire anemometers is that it incorporates a real-time SD card data logger.
The HHF-SD1 measures velocity, and air temperature, and has an input socket that accepts a Type J or K thermocouple that can be used as a highly accurate thermometer. The integrated hot wire and standard thermistors provide fast and accurate readings-even at low velocities. The HHF-SD1 is innovative and easy to operate. Download data from the SD card into an Excel spreadsheet without the need for special software.

Useful for outdoor wind monitoring
Has worked as advertised for us. Anything that outputs a .csv rather than some proprietary filetype is worth it as far as I am concerned.

Can I know its frequency response range?
Thank you for your inquiry about the anemometer. The response time is instantaneous when measuring air flow and to data log, it is user define to record in various times:
0, 1, 2, 5, 10, 30, 60, 120, 300, 600, 1800 or 3600 seconds (0
seconds to 1 hour)

Hi, ihave 2questions:1)when i put aKthermocouple tomeasure velocity and low temperature does itaffect the measurement of velocity because the device normally works from 0 to 50°C,2)would it also give a temp/veloc vs time plot when i put this thermocouple.
Thank you for your inquiry. If you plan to measure below or at lower temperatures, it will not measure accurately and it will not provide a velocity plot.

How many hours of continuous measurement can Hot Wire Anemometer with Real Time Data Logger (Item# HHF-SD1) do while logging. Can it be set to take measurements only at certain intervals e.g. every 10 seconds?
Thanks for your question. This model can be set for one of the following sampling times: 0, 1, 2, 5, 10, 30, 60, 120, 300, 600, 1800 or 3600 seconds. The length of time this unit is able to record depends upon the sampling time selected and the size of the SD card being used. Also, depending on the sampling time and how long you intend to record for, you may want to get a 9-VDC adapter to power the unit PART # ADAPTER-SD.

Hi, May i know is this a Constant Temperature Anemometer (CTA)? Could this be able to measure air velocity (or possibly other turbulent properties) in a high turbulence condition (Turbulence intensity 5%)?
Thank you for your inquiry. This anemometer is not CTA, as it can do temperature compensation. Also, this meter is meant for turbulent applications.

Does this product come with a certificate of calibration?
Yes, there is an option to include a NIST Certificate and that part number is HHF-SD1-CAL-3.

Can we write our own software to automatically read data from the instrument? Where can we find the commands?
Thank you for inquiry about the hot wire anemometer and would advise if you can compose an email and send it to flow@omega.com and can provide the information.

When taking velocity measurements, the meter will show increasing velocity until about 3100 ft/ min. As air speed increases beyond this, the measurement will decrease and a '-' sign appears at the far left. What does this mean and how to fix?
Measurements are coming close to the upper measurement limit for this device (3940ft/min). But for why the measurements would start decreasing and '-' code, I don’t have an answer. The unit will need to come back for evaluation.

What frequency range is this able to measure? What is the format of the output, a time series or does it provide any FFT outputs?
Thanks for your question. The HHF-SD1 does not measure frequency; it measures velocity and temperature and it only has a serial communication output RS232.
