What's the difference between the extech ea11a and the extech tm100?

Hello Daniel,The EA11a can accommodate Type K probes, while the TM100 can accommodate Type J and K. As well, the TM100 has a wider temperature range and tighter accuracy spec's. Data sheets for both are available here:http://www.extech.com/resources/EA11A.pdfhttp://www.extech.com/resources/TM100data.pdfBest Regards

can it measure water temperature?

Yes, you can measure the temperature of anything with it, just need the appropriate probe for what and how you're measuring. There are hundreds of different probe types available that will connect to this unit.

I am having issues where the sdl200 will "freeze" after a couple hours of data logging. it will start working again if i stop the logging. any fix?

The manufacturer answered that you can visit their website and find Tab "Support" -> "Service & Support" -> "Technical Support" and there you can find the number of Technical Support and ask them questions about your item. Thanks
