Product review (3 stars): Non-matching thermometers
It's a nice product, but the one they sent me had thermometers that disagreed by a little over 1 degree C. this difference will result in an RH reading being off by 10 to 15%, making the unit of little value..
I could just adjust my wet bulb reading by 1.2 degrees C, and then calculate RH, but I really expect the product to come from the factory with the thermometers at least matching, if not accurate.
I contacted the manufacturer and was told they wouldn't honor the warranty because it wasn't purchased through an authorized distributor.
Is Amazon operating on the black market?
