Oakton hygrometers provide a high degree of accuracy and reliability. This 5 Inch wall mountable unit provides the convenience of being able to monitor both temperature and humidity. Digital temperature display uses a solid state temperature detector. The natural hair-bundle hygrometer provides an exceptional degree of accuracy across a broad range (+/- 4% from 20-90%RH). Many units provide high accuracy through mid range (25-65RH), but few provide this degree of accuracy through so broad a range. This is our choice when accuracy is of paramount importance.
