General Tools RHXL3SD - Handheld Thermometer/Hygrometer Data Logger

The RHXL3SD comes with a temperature-humidity probe that is used to make the first three types of measurement. Surface temperature measurements are made using an optional Type K or J thermocouple.

Several features and capabilities enhance the RHXL3SD’s versatility. Among them are automatic temperature compensation for dew point, wet-bulb and thermocouple measurements; the ability to hold readings and display maximum and minimum readings; and an automatic power off function that extends battery life. Because it is microprocessor-based, the RHXL3SD can make full use of the portability, reliability and large storage capacities that SD memory cards offer. Measurements can be made automatically at any sampling rate between one second and one hour. After the instrument time-stamps and stores the measurements (Temperature and Humidity only) on an SD card plugged into it, the user can remove the card and plug it into a laptop or desktop computer either directly or via a USB card reader. The logged data is stored on the card as files that can be opened by Microsoft’s Excel application. Unit accepts SD memory cards as large as 16 GB. The RHXL3SD has a backlit 2½" diagonal display and is powered by 6 "AA" alkaline batteries or an optional AC adaptor.
