Is a transmitter for a thermocouple. Looks fine, until you pull up the specs ( http://www.prelectronics.com/ ): it's actually a 16 bit ADC, which limits the output resolution significantly (nothing I didn't suspect, but always good to check!).

What resolution are you looking for Ben? 16 bits is not low in my little world. Haven't really studied the spec sheet closely but it looks to me like you'd get at least 0.0091C resolution for the full range with a type T thermocouple. More if you limit the range, the analog resolution seems to be 18bits, wouldn't that be 0.0022C over a range of 150C? Accuracy seems OK too.

My quick take.
