I purchased three BALDR Digital Thermometer Hygrometer Monitor Indoor Temperature & Humidity Gauges then placed all of them together next to a reference weather station monitor. Allowing a short time for settling and less than ten minutes later all of the gauges indicated the same temperature and humidity. Afterwards they were placed into different locations within the house indicating the various temperature and humidity readings which I knew were correct. I have observed that these gauges are accurately responsive to indoor environment changes which is important to understand what is going on. So far, so good.

I am using this in my attached heated garage to determine the temperature in the winter
