A traditional weather watching instrument with a twist! Perfect for the garden or greenhouse.
This Masons Wet and Dry Bulb Hygrometer is a traditional meteorological instrument ideal for seasoned weather watchers, as well as those new to the hobby. Inspired by the wild flowers of the hedgerows and meadows of Great Britain, our hygrometer features a beautifully designed back plate, and comes with a comprehensive manual and guide to hygrometric conversion.
A wet and dry bulb hygrometer consists of two thermometers. The dry thermometer stands alone, whereas the wet hygrometer extends into a small water tank via a piece of hygrometer wick. Using a conversion table, the dry bulb temperature and the web bulb depression, you determine the relative humidity - a key parameter when assessing growing conditions, both inside and out. It's an ancient art that is quick to get your head around, and helps you get to know your garden better.
The protective roof shields your hygrometer from falling rain, and the detachable water tank makes it straightforward to top up the water for your readings. Use one or both of the mounting hooks for easy installation on a fence post, wall or shed.
