DataloggerXP software, working in tandem with Crystal Engineering's XP2i Digital Pressure Gauge, allows you to record up to three thousand measurements on an intrinsically safe, fully temperature compensated pressure gauge. With the XP2i's long battery life, you can take measurements for up to three months without the need for external power supplies or battery replacements. The DataloggerXP program and XP2i Digital Test Gauge form an integral data logging solution. The software application handles all of the transfer and saving of data to your computer's hard drive, while the XP2i performs all of the actual data collection. Once measurements have been collected and transferred , DataloggerXP can save the data files directly into a Microsoft® Excel spreadsheet; or, if you prefer, a comma-separated text file. There's nothing else like it!
