The HHEM-SD1 meter comes with a multi-function probe that is used to make air speed, humidity and light measurements. Surface temperature and sound level are made using optional accessories. Several features and capabilities enhance the meter’s versatility, among them are automatic temperature compensation for measurements made by the anemometer, a Type K or J thermocouple input, the ability to hold readings and display maximum or minimum readings, and an automatic power off function that extends battery life. Because it is microprocessor-based, the HHEM-SD1 can make full use of being portable. Reliability and large storage capacities are enhanced by an SD memory card. Measurements can be made automatically at any sampling rate between one second and one hour. After time-stamping and storing the measurements on an SD card plugged into the instrument, the user can remove the SD card and plug it into to a laptop or desktop computer either directly or via a USB card reader. The data is stored on the card as files with the .xls extension, which can be opened by Microsoft’s Excel application. The HHEM-SD1 has a backlit 2½" diagonal display and is powered by 6 “AA” Alkaline batteries (included) or an optional 9 Vdc AC adaptor.
