CBL 2™

An easy way to collect and analyze real-world data.

Features Summary

The CBL 2™ system, the second generation of the Calculator-Based LaboratoryTM system, 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™ 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.
