The software costs $85 and the USB temperature probe can be purchased form Vernier Sci. for around $40. Details and more complete description of CT features and requirements are on the website. The manual and a demo version are downloadable for free from: http://curtpalm.com/Software.html. The demo version does not support use of the temperature probe, but one can set the temperature manually to demonstrate the compensation features.
