Great wireless digital thermometer

I purchased 2 of these temp meters to wirelessly monitor fridges that I repair. I particularly like the large digital display for the remote sensor that can be easily read from quite a distance and the long range that Ecowitt have with there products ( I have their weather station which is brilliant also). They typically are also very accurate.
