Rated 2 out of 5 by bob1 from Not even close I've installed one of these so far. It read 84 F. I checked it with two accurate (expensive) and they both read 71 F. Apparently I need to calibrate it. I hope the rest are a little closer.

Rated 1 out of 5 by IBS Guy from Troublesome Product Constantly read high. Was told by customer support that the unit could handle 18 volts DC maximum despite the fact that the documentation said 24. Changed to a 15 volt supply and still had the same problem. Used a heat gun on the unit and noticed the board had a 90° hot spot on it. Maybe the RTD was picking some of that up. In the end I went with something else.
