Product review (5 stars): This is much better accuracy that on other hygrometers that I have purchased ...
I already had two of these units that I bought at a local guitar store, and then bought three more from i-Tronics. These items arrived very quickly. Placing the five units that I now have next to each other, three read the same, one reads 1% less humidity, and one reads 1% more humidity. The temperature reading are the same for all five. This is much better accuracy that on other hygrometers that I have purchased in the past, usually for more money that the TermoPro units cost. I would recommend these units to anyone, and would recommend purchasing them from i-Tronics because of their excellent service.
