The Casio EA-200 Data Analyzer is a fast data collection device that connects to the Casio FX-2 Graphic Calculator. While there are only three Casio sensors, the full range of everything you can measure is made up by the established Vernier range.

Pros: a good way forward for maths people using Casio calculators. A great way for science and maths to work together. Uses the well established range of Vernier sensors.

Cons: No track record in science

Verdict: it’s never been clear to me at least whether Casio is really here and serious. If the kit appeals, be sure to get all you need as I fear that when it’s gone, it’s gone.
