Concrete Temperature Monitoring

[moskey]

Does anyone have experience with multiple methods of monitoring temperature in mass concrete? What has worked the best/worst? How do the prices compare with each other? What method is recommended?
I am looking to purchase some equipment to monitor internal temperatures in mass concrete. I have a little experience with thermocouples, and from what I've been told have a margin of error of +/- 3 degrees. I recently found a product called intelliRock. The margin of error with this is +/- .001 degree C. My only reservation on this is that it is rather expensive.

Thanks!

I don't know much about measuring the temperature of concrete, but I'd be willing to bet that 3 degrees is close enough and 0.001 degrees is ridiculously accurate and completely unnecessary.

Actually, when the specs hold you to a 35 degree difference between the core and the edge of the mass concrete, +/- 3 degrees is too great of a margin of error. That is why I am pursuing something more accurate.

We've used a data logger with thermocouples and they seem to work quite well.
