Flawed, a little annoying, but usableWe bought this because it records B-type TCs. The power adapter does not provide power, so it's batteries only. Power it off, power it back on, the date is reset, and it is tedious to re-enter it. It can be programmed with the date automatically if connected via cable to a PC running the software, but that's a pain, especially for a portable unit. Otherwise, it does its job. It does remember what recording interval and type of TCs, just not the date and time. Data downloads fine - rename the ending .CSV and it opens in Excel.

meter fine, software awefulMeter has been adequate but the data-logging software has been useless. This meter has driver issues connecting to computers in the first place. I have only found it to work on 2 of the 5 computers that ti have installed it on. Not sure why. My IT department has not figured it out either. Software is not stable on computers that will connect. program crashes frequently especially every time you plug in or unplug a thermocouple wire. Have been trying to log temperature overnight and cannot get software to run long enough to do so.

Does the job2nd one I have purchased, gets a lot of demand for use on thermal qualification. Does what is needed for an ad-hoc "I need to log temperature on this point" and its known downsides aren't really a problem. Data is spit out in a CSV compatible format, just ignore the filename extension (or copy/paste from notepad++).
Full disclosure on downsides:
-PC interface works, but it a bit dated and data download is slow (might take a minute rather than being instant)
-Chews through batteries on longer tests (eg. 24hr), power adapter is recommended
-Does not remember the date after power-off. I treat it as a stopwatch from power-on
-Not really useful to log once every 2 seconds due to refresh rates on multiple thermocouples not exceeding this. I usually just set it to once every 10 seconds anyways since parts I test change temperature sluggishly.
