PASCO Scientific has unveiled a powerful new graphing data logger, the Xplorer GLX. For $299, the device gives students and teachers ultimate flexibility in setting up a science lab wherever they need it, with or without a computer, the company said. PASCO took the best aspects of a computer–including a high-resolution display, large memory (10 megabytes), an operating system, a file-management system, and direct connection to a printer–and incorporated them into the Xplorer GLX, enabling students to capture data in real time; graph, analyze, annotate, and store a full day’s worth of lab experiments; and print the data by connecting directing to a printer. Because the Xplorer GLX is small and highly mobile, it’s perfect for field experiments, PASCO said. The unit contains four built-in sensors (two temperature, one voltage, and one sound) and four additional sensor ports. A high-resolution, backlit screen (320 x 240 LCD) allows data to be viewed even in bright sunlight or low-light conditions, and a voice annotation feature allows students to relate events to collected data easily during later analysis.
