All thermometers/thermocouples have been tested and found to be within one degree of each other. Only "Bad" part, when I ordered them I found they were shipped direct from China and took a little longer to ship. Does the US stop producing? I've used two of these to monitor my hive's temperature. As far as I know, the bees haven't chewed on the insulation on the wires yet. The wires are thin, easy to route into the hive and easy to attach. The price was good, I didn't need expensive "super scientific" thermometers.
