xls extension, which can be opened by Microsoft’s Excel application. The data logs are stored on the card as files with the. After storing and time-stamping the measurements on an SD card plugged into the instrument (a process called datalogging), the user can remove the card and plug it into to a laptop or desktop computer either directly or via a USB card reader. Measurements can be made automatically at any sampling rate between one second and one hour. The unit has the ability to hold readings and display maximum and minimum readings and an automatic power off function that extends battery life.īecause it is microprocessor-based, the AF-GT-HWA4214SD can make full use of the portability, reliability and large storage capacities that SD memory cards offer. Among them are automatic temperature compensation for measurements made by the telescoping probe or by Type K or J thermocouples. Several features and capabilities enhance the instrument’s versatility. Temperatures can be displayed in ☏ (Fahrenheit) or ☌ (Celsius) units. Air speeds can be displayed in m/s (meters/second), fpm (feet per minute), km/h (kilometers/hr), knots (nautical miles per hour), or mph (miles per hour). The AF-GT-HWA4214SD comes with a telescoping air speed-temperature probe. Balancing velocity profiles in furnaces and refrigerated cases.Measurement of air velocity produced by fans and blowers.Maintenance and repair of air conveyors and flow hoods in clean rooms.For this reason, they are commonly used for precise measurement of low-speed air flows, turbulent flows, or of any flow in which rapid velocity fluctuations are of interest. In the AF-GT-HWA4214SD, the hot wire is located at the end of a telescoping probe where it is paired with a tiny glass bead thermistor that measures air temperature.Ĭompared to other types of anemometers, hot wire anemometers have superior performance. The speed of the air flow can be calculated from the relationship between the metal’s electrical resistance and temperature. Surface temperature is measured by an optional Type K or Type J thermocouple.Īll hot wire anemometers, including the AF-GT-HWA4214SD have at their heart a very thin metal wire that the instrument electrically heats up above ambient temperature. The AF-GT-HWA4214SD is a general-purpose handheld instrument that can make two kinds of measurements: air (wind) speed and temperature (simultaneously). 1-2 Day Lead Time for Fast and FREE Delivery.Powered by six “AA” batteries or optional 9V AC/DC adapter.Accepts SD memory cards of up to 16 GB capacity.Also supports manual data logging and changing of SD card storage location.Automatically logs measurements at sampling time settable from one second to one hour.Displays maximum and minimum readings and holds any reading.diagonal) front-panel green backlit LCD is easy to read
