The HHF1000 series handheld air velocity/temperature meter measures and displays air velocity and air temperature in research and development labs, HVAC applications, and other manufacturing processes. The sensor design is based on three RTD elements, one measures air temperature and the other two measures air velocity due to the heat loss from the RTD sensor as it cools down by the air flow. The sensor probe is offered in two configurations, fixed probe and remote telescopic probe. The HHF1000 series offers many standard features such as high and low alarm indication, USB PC serial interface with a Windows based data logging software, adjustable display response time, volume air flow readout, and atmospheric pressure compensation. The HHF1000 displays the air velocity in different Engineering units such as FPM, m/sec, Miles/Hour, and Km/ hour. The air temperature is displayed in ºF and ºC.
