Venier LabPro...The Vernier LabPro is the only data-collection device that offers you four different ways to collect data. You can use LabPro with a computer, Texas Instruments graphing calculator, Palm handheld, or on its own as a remote data collector. The Vernier LabPro interface is the heart of their data-collection system, offering unparalleled power, versatility, portability, and ease of use at an affordable price. The LabPro has been used in classrooms for over five years as the trusted interface for science and math data collection. LabPro can be used with Windows or Macintosh computers. Our award-winning Logger Pro computer software allows students to collect, display, analyze, and report data quickly, accurately, and easily. LabPro connects to popular TI graphing calculators using the included cradle and cable. Use our EasyData or DataMate calculator software for data collection anywhere in your school or in the field. With the Palm data-collection package (sold separately) and a Palm Powered handheld, you get a portable data-collection system with the power of a PDA. Analyze your data directly on your handheld or upload to a computer using HotSync technology. In remote mode, you can take LabPro to an amusement park and collect data without a computer or handheld attached.
