Omega's new RHXL3SD Handheld Thermometer/Hygrometer Data Logger comes with a temperature-humidity probe and a two-GB SD card. It features 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. The large, backlit dual LCD display allows for easy reading, the company says.
