Features summary

The CBL™ 2 data collection device, the second generation of the CBL™ device, is a portable, handheld, battery-operated data-collection device for gathering real-world data. Data collected with a CBL™ 2 device can be retrieved and analyzed by TI graphing calculators. With the CBL™ 2 device and appropriate sensors, you can measure motion, temperature, light, sound, pH, force and much more.

Over 50 sensors from TI and Vernier Software & Technology are available making the CBL™ 2 data collection device ideal for middle school math, science, biology, chemistry, physics and high school math. Students discover how math and science affect the world around them by developing hypotheses, conducting experiments and forming conclusions.
