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.

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.

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?
Asked by: Dammy
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.
